4 Our Mission Guhring s mission is to provide customers with the means to take cost out of machining production components by improving machine process times and product quality. Our regionally located application sales engineers work one-on-one with companies to reduce their holemaking costs, thereby enhancing company profitability and competitiveness. Holemaking performance improvements achieved with Guhring tooling are detailed in computer-generated reports that quantify time and cost savings. Our R&D Strengths The competitive edge gained by Guhring customers is driven by our extensive global commitment to research and development. This international commitment addresses customers needs in the automotive, aerospace, heavy off-road equipment and other industries. Guhring simultaneously designs and engineers cutting tools in partnership with machine tool builders to ensure that new machines incorporate the latest tooling technology. New cutting tool geometries, substrate materials and coatings regularly evolve from these Factory of the Future programs. Our Manufacturing Technology Guhring cutting tools are manufactured on customdesigned CNC grinding machines that produce tolerances better than the industry standard. These tighter tolerances contribute to extended tool life, improved tool performance and part quality. Product availability is guaranteed when tied to the Guhring Tool Management Program. Our Standard Product Offering As global leader in cutting tool design and development, Guhring offers the industry s broadest selection of tool substrates, geometries, coatings and sizes. From HSS and HSCO tooling to the latest ultra-fine grain carbide grades, solid to coolant-through, low to high helix, two to multiple flute, bright finish to multilayer coatings, no one offers more. This breadth of selection maximizes our ability to provide ready solutions to customer s diverse holemaking challenges. Our Special Tool Capabilities Often, applications demand taking tool selection to a higher level. Guhring thrives on the opportunity to put our expertise and experience to work in customdesigning the optimal tool for the job. Special tooling can deliver faster cycle times, better hole quality and lower cost. In addition, custom-designed tooling often leads to the elimination of entire machining operations, further enhancing holemaking cost savings. ISO 9001 Certified Guhring was one of the first cutting tool companies to be certified ISO This includes plants in Europe, as well as our Brookfield, Wisconsin manufacturing facility. This certification endorses the superior quality and consistency employed by Guhring throughout the manufacturing process. Attention to detail right from quotation to order entry, engineering, material procurement, manufacturing and delivery is the essential element that differentiates Guhring from other suppliers. 80 % MACHINING COSTS 4% TOOL COSTS 16% COOLANT COSTS Tool & Coolant Costs in relation to Total Manufacturing Costs CONTENTS For more information on Guhring products /distributors, contact Corporate Office at In California, call On the Internet, visit us at 3 Page Terms & Conditions About Guhring Standard Drills Index By Length / Style Micro-Precision Drills HSCO NC Spot Drills HSS Carbide Center Drill-Countersinks HSS Carbide Screw Machine Length Drills HSS HSCO PM NEW!

17 High Performance Geometries New 12xD Series! Also... New Sizes! HIGH PERFORMANCE CARBIDE DRILLS THE POWER OF FIVE To double tool life, increase cutting speeds/feeds, and cut holemaking costs. Improvements in cutting tool performance typically come to the market in slow, incremental stages. A new coating here, a new point geometry there... Not so with GUHRING s new SL CARBIDE high performance drill line. SL CARBIDE combines breakthroughs in everything from coatings to carbide to reconditioning. The end result is drills that last up to two to three times as long as even the best TiN-coated carbide competitor, deliver much higher cutting speeds/feeds, produce near-burnished hole finish, and, ultimately, drive down cost-per-hole to a fraction of what it was. Even better, the SL CARBIDE line is designed to deliver these benefits to the broadest possible range of applications and material types. SL CARBIDE drills are available in lengths up to 10xD, solid to coolant-through, and straight to multiple flute. SUPER-TOUGH DK460UF (K40) ULTRA-FINE CARBIDE. Only carbide substrates have the superior strength and rigidity to take full advantage of today s high performance CNC machines. If carbide is good, GUHRING carbide is even better. Our DK460UF (K40) ultra-fine grain carbide is 50-60% tougher than common carbide grades. It delivers improved cutting edge strength and stability, preventing premature chipping and material loading. The ultra-fine grain size also allows SL CARBIDE tools to be given sharper cutting edges. The end result is significantly improved tool life, better holemaking consistency and broader tool application. HIGH PENETRATION UNIVERSAL POINT GEOMETRY. For universal application, the SL CARBIDE line includes drills featuring the GUHRING selfcentering high performance SU point, which reduces the tool s tendency to push material at the chisel edge. The push-pull effect of this unique point design reduces axial thrust loading and heat generation, improves tool centering and life, and provides freer cutting and high penetration rates. At 140, the point angle produces a narrower chip to facilitate chip evacuation at high speeds. Other SL CARBIDE tools include straight-flute drills for accurate, high penetration up to 10xD, and drills with three-flute construction which remove more material per revolution than traditional two-flute drills. HIGH PERFORMANCE FIREX MULTILAYER COATING. Not since the introduction of TiN has a tool coating had such a universal impact on tool performance. The distinctive red-violet colored FIREX coating consists of alternating ultra-thin TiN and TiAlN layers combined to form a super coating that sets the industry standard for cutting tool performance enhancement. Key features of FIREX include: thermal barrier that prevents heat buildup, delivering two to three times the tool life of TiN; universal applicability, much more widely applicable than TiAlN or TiCN; and high density and toughness, with hardness exceeding 90 Rc. ADVANCED MANUFACTURING TECHNOLOGY. Producing drills conventionally requires that the part be moved from grinding machine to grinding machine and re-setup for every machining operation. Ultimately, upwards of 10 different machines can be involved. The SL CARBIDE line, however, is produced on revolutionary new GUHRING US 125/135 Grinding Stations, which enable the production of a drill start-to-finish in just one setup. SL CARBIDE drills can be produced faster to meet higher demand. More importantly, even the most critical tolerances are easier to hold because of the elimination of multiple setups and frequent handling. FACTORY-DIRECT RECONDITIONING SERVICE. Returning the original SL CARBIDE tool to its original quality, condition and performance is of critical importance when it is time for resharpening and recoating. Now GUHRING has made this process as easy and streamlined as getting a new tool, with our new Factory-Direct Reconditioning Service. The same high-precision CNC machines and coating systems are used, and the service is faster, more convenient and more cost-effective than any alternative.

19 High Performance Geometries RT 800 WP INTERCHANGEABLE-INSERT DRILL For Large Diameter Holemaking New Sizes! Now up to mm diam. RT 800 WP ADVANTAGE. The RT 800 WP ultra-fine carbide interchangeableinsert drill revolutionizes large diameter holemaking, delivering feed rates up to 10 times higher than conventional tooling and bringing long-sought improvements in machining cost and performance. The combined benefits of the RT 800 WP s many features enable the tool to outperform both conventional spade drills and carbide-tipped brazed tools across a wide variety of materials. Whereas the straight, Plain Jane cutting edge of spade drills fractures and must be pushed through materials, the RT 800 WP s high performance SF point cuts and pulls itself through the workpiece, providing significantly higher penetration rates, longer tool life, reduced heat generation, and lower required torque and horsepower. The RT 800 WP s coolant-through, semi-helical flute design then delivers improved chip evacuation and further heat reduction. While carbide-tipped tools may feature high performance point geometries, they lack the overall flexibility and cost effectiveness of the RT 800 WP. Brazed tools can only be used to produce on specific hole size, whereas each RT 800 WP body can be used with a range of inserts to produce a variety of hole sizes. In addition, while brazed tools can be reground, some performance is typically lost after resharpening and recoating. By contrast, each new RT 800 WP insert features an original factory point grind and coating. Also, the combined inserts-to-body life, and hence overall tool life, of the RT 800 WP is much greater than that of a brazed tool, further reducing tooling costs and cost-per-hole. Key features of the RT 800 WP include: DK460UF (K40) carbide cutting inserts. This ultra-fine grain carbide was developed in-house by GUHRING specifically for cutting tool applications and is 50-60% tougher than common carbide grades. In particular, it delivers improved cutting edge strength and stability, preventing premature chipping and material loading. The ultra-fine grain size also allows tools to be given sharper cutting edges. Significantly improved tool life, better holemaking consistency and broader tool application are among the key benefits of DK460UF. Aggressive, self-centering 140 SF point. The push-pull effect of this unique point reduces axial thrust loading and heat generation, improves tool centering and life, and provides freer cutting and higher penetration rates. At 140, the point angle produces a narrower chip, which facilitates chip evacuation at high speeds. Designed with a high rake angle, this point is very effective in high alloy steels. Inserts are available in fractional diameters from 11/16 inch to 1 inch and in metric diameters from mm to mm. Durable, nickel-treated HSS bodies are available for drilling depths of 3xD, 5xD or 7xD, with fractional or metric diameter shanks. Coolant-through, semi-helical flute design. These features deliver improved chip evacuation and heat reduction, extending tool life and facilitating higher speeds and feeds. TiN and multilayer FIREX coating. Performance benefits include increased tool productivity, reduced machining friction and heat, and high resistance to edge buildup and galling. 18 For more information on Guhring products /distributors, contact Corporate Office at In California, call On the Internet, visit us at

20 GS 200 U / G HIGH PRECISION THREE-FLUTE CARBIDE DRILLS New Sizes! #5518 now mm GS 200 ADVANTAGE. The GS 200 is a high precision three-flute drill capable of performing first-class drill-reaming in one pass. Whereas carbide tools typically require super-rigid setups, the GS 200 s sturdy design permits use on a broader range of machines, where less strict rigidity and uniform feed requirements are met. Key features include: DK460UF (K40) carbide. Ideal for use in cast iron and aluminum alloys, this ultra-fine grain carbide was developed in-house by GUHRING specifically for cutting tool applications and is 50-60% tougher than common carbide grades. In particular, it delivers improved cutting edge strength and stability, preventing premature chipping and material loading. The ultra-fine grain size also allows tools to be given sharper cutting edges. Significantly improved tool life, better holemaking consistency and broader tool application are among the key benefits of DK460UF. GUHRING is one of the few cutting tool companies that manufactures its own carbide. Manufacturing our own carbide in-house gives us greater control over the entire production process, from substrate procurement to the finished tool. Three cutting edges. The GS 200 s three-flute construction removes more material per revolution than traditional two-flute drills. In addition, the extra flute enables the GS 200 to track straighter while in the hole, vastly reducing runout. The third land produces a burnished-quality surface finish, thereby eliminating the need to ream separately after drilling. The three-flute design also allows the drill to start or end on uneven surfaces and to handle interrupted cuts without deflection. GS 200 U Self-centering 150 U point. Extensive web thinning produces an aggressive, naturally self-centering universal point, eliminating the need for spotting and reducing the drill s tendency to wander. The 150 point angle aids in accommodating the third flute and contributes to the production of narrower chips. Self-centering 130 G spiral point. Sharing many of the benefits of the U point, the G point sports a spiral design which provides top performance when machining gray cast iron, spheroidal graphite iron, malleable cast iron, aluminum alloys, magnesium alloys, brass, steel and cast steel.

Key features include: DK460UF (K40) carbide. This ultra-fine grain carbide was developed in-house by GUHRING specifically for cutting tool applications and is 50-60% tougher than common carbide grades. In particular, it delivers improved cutting edge strength and stability, preventing premature chipping and material loading. The ultra-fine grain size also allows tools to be given sharper cutting edges. Significantly improved tool life, better holemaking consistency and broader tool application are among the key benefits of DK460UF. Rigid, straight-flute design. This design eliminates the spring effect common with helical flutes and significantly increases tool rigidity. As a result, the RT 150 GG can be fed more aggressively, while delivering hole concentricity and straightness up to six times better than standard HSS twist drills and up to two times better than carbide twist drills. Double margin. Hole quality is further enhanced by the RT 150 GG s double margin, which provides minimal deviation from straightness and excellent self-centering performance. This feature enables the RT 150 GG to produce a burnished-quality hole finish, eliminating the need for secondary operations such as reaming or boring. Straight coolant ducts. 120 point. 0 helix. Bright finish with polished flutes to fight chip welding. Available in lengths for drilling to 4xD and 10xD deep. 20 For more information on Guhring products /distributors, contact Corporate Office at In California, call On the Internet, visit us at

22 HSCO Micro-Precision Drills FOR EXTREMELY ACCURATE SMALL DIAMETER HOLEMAKING The continued trend toward increasingly small precision components with increasingly tight tolerances can present daunting machining challenges. To address these needs, GUHRING offers three series of HSCO micro-precision drills in diameters from mm ( in.), both righthand and lefthand cut, and in bright finish and TiN coated. GUHRING MICRO-PRECISION ADVANTAGE. GUHRING micro-precision drills are manufactured on custom-designed machines, which deliver the industry s tightest tolerances (+0.000/ mm). Other features include: M35 High Speed Cobalt Steel. The HSCO grade commonly used for cutting tools in Europe, M35 has a lower cobalt content ( %) than its U.S. counterpart, M42 ( %). As such, M35 is lower in hardness ( Rc for M35 versus 68.5 Rc for M42), but higher in toughness. The difference in hardness may appear slight, but it can greatly affect tool life: The higher the tool hardness, the more brittle the tool. If machining conditions and setup rigidity are less than ideal, which is a constant challenge with micro-precision machining, M35 is much less susceptible to chipping and breakage. Reinforced shank. GUHRING micro-precision drills are manufactured with an oversized, reinforced shank to fight tool breakage. All sizes are covered by three different shank diameters, saving time, improving machining accuracy and reducing the need for attachments. HSS CARBIDE NC Spot Drills Spotting on CNC machines requires a very rigid, high precision tool. Available in HSS and carbide with 90 or 120 points in short or long lengths, GUHRING NC spot drills lead the industry in tool life and precision. GUHRING NC SPOT ADVANTAGE. If you are currently using combined center drill-countersinks, GUHRING NC spot drills can substantially reduce machining times. GUHRING NC spot drills can run at higher speeds and feeds; and since it is not necessary to drill as deep, cycle time is further shortened. In addition, centering and chamfering can still be accomplished in one operation, provided that the spot drill used is larger than the followon drill. Other features include: A very narrow chisel, shorter than that of the follow-on drill. A small, constant web which eliminates the need for thinning even after multiple regrinds. An outer diameter tolerance of h6. Short flute and overall lengths. No body clearance or taper, which enhances tool rigidity.

A few application examples: Challenge 1 Drilling with carbide stepped drills in highly abrasive material resulted in less-than-optimum tool life of 2,500-6,000 holes per tool. Solution 1 Changing to PCD tool material increased tool life to over 77,000 holes! Challenge 2 Drilling and tapping in Si-ceramic material proved highly abrasive. Carbide tools failed. A galvanized diamond-coated tool achieved only 90 holes with a drilling time of 30 seconds per hole. Solution 2 Short PCD drill achieved tool life of 110 holes on average and a drilling time of just 1.5 seconds per hole a 95% reduction! Challenge 3 Reaming of holes for tappet clearance in a V6 turbodiesel AlSi10Mg (Cu) cylinder head required long cutting interruptions in varying planes and directions. Close tolerances, high surface finishes and smaller deviations in concentricity were needed. Solution 3 PCD-tipped step reamer delivered 120,000-hole, 10,000-cylinder head tool life. 24 For more information on Guhring products /distributors, contact Corporate Office at In California, call On the Internet, visit us at

26 HSK Toolholding MODULAR SYSTEMS MAXIMIZE TOOL PERFORMANCE Non-rigid machining environments severely undermine cutting tool performance, shorten tool life, and increase the risk of tool chipping and breakage. While many types of toolholder are effective in reducing concentricity error, only hollow-shank short taper (HSK) toolholding systems provide the rigidity, accuracy and repeatability required for optimum tool performance. TECHNOLOGICAL LEADER. Guhring was among a consortium of leading machine tool builders, cutting tool manufacturers and end-users which worked to develop the German HSK Standard DIN This standard details the design specifications for a rigid, high speed toolholding system offering universal application, automatic and manual tool changes, high radial and axial accuracy, and through-the-spindle coolant. Designed in strictest compliance to the HSK standard, Guhring s GM 300 Modular HSK Toolholding System delivers unsurpassed speed, rigidity, precision and ease of use, enabling manufacturers to realize fully the machining quality and cost savings benefits of high performance tooling, particularly high performance carbide cutting tools. OUTPERFORMING THE COMPETITION. Better suited to high speed machining than conventional steep taper adapters, the GM 300 offer numerous performance advantages: High stiffness and torque transmission, providing more than double the rigidity of conventional V-flange toolholders. Extraordinary precision, achieving radial and axial repeatability within 3 µm. High spindle speeds (20,000+ rpm). GM 300 toolholders feature full taper-face contact and a special internal clamping mechanism. The latter design element causes clamping force and toolholding rigidity to rise as spindle speed increases, whereas the opposite is true with conventional design toolholders. Extreme concentricity that extends tool life and delivers optimum hole tolerance. Shorter shaft length and lighter weight for faster tool changing and less wear and tear on tool changes. BREADTH OF SELECTION. Guhring s standard line of GM 300 toolholders and accessories ranks as the most comprehensive in the industry. Items are available for immediate delivery in both HSK Form A (automatic tool change) and HSK Form C (manual tool change). In addition, we can design and produce toolholders to customer specifications.

27 Coating Services Wear-Resistant Hard Coatings & Lubricating Soft Coatings HIGH PERFORMANCE THIN-FILM COATINGS FOR CUTTING TOOLS & WEAR PARTS The importance of advanced coatings in achieving dramatic gains in cutting tool and wear part performance cannot be overstated. Properly applied, coatings improve many tool and part characteristics. They increase surface hardness, lower the friction coefficient and thermal conductivity, and provide a chemically inert surface. Performance benefits include: significantly increased tool and part life, reduced friction and heat buildup, and high resistance to edge buildup, galling and fissure propagation. Applying the right coating can increase tool and part productivity from 100% to over 1000%! TECHNOLOGICAL LEADER. As a cutting tool manufacturer, Guhring offers a level of technical expertise without equal in the industry. Guhring was the first to introduce TiN coating (Titanium Nitride) to cutting tools in 1980 and has remained a global leader in developing and applying new coating technology to improve both cutting tool and wear part performance. Today, Guhring offers a full range of high performance thin-film coatings to meet customers diverse needs, including: TiN (Titanium Nitride, or S-coat), TiAlN (Titanium Aluminum Nitride, or A-coat), TiCN (Titanium Carbonitride, or C-coat), FIREX (Special Multilayer Hard Coating, or F-coat), and Other advanced hard, soft and combined coatings. Each application presents different performance challenges, and Guhring s advanced coating selection provides application-specific solutions, delivering higher hardness, increased heat and shock resistance, and greater lubricity as required. By effectively matching the right high performance coating to each application, GUHRING COATING SERVICES maximizes tool and wear part productivity and cost effectiveness providing absolute value for money. STATE-OF-THE-ART EQUIPMENT. Coatings are only as good as the process used to apply them. Advanced equipment, special training and experience are vital. LONGER TOOL & WEAR PART LIFE FASTER OPERATING SPEEDS & FEEDS SIGNIFICANTLY INCREASED PRODUCTIVITY Guhring utilizes both state-of-the-art cathodic arc and reactive ion coating systems to deliver superior coating adhesion, uniform thickness and structure, and batch-to-batch reproducibility. Advanced climate control systems maintain optimum facility air temperature, humidity and pressure, while removing dust and other airborne impurities. A customdesigned, fully automated ultrasonic cleaning system maximizes tool and part pre-coating cleanliness, while precision stereo dynascopes enhance both pre- and post-coating visual inspection. Coating adhesion and thickness are closely monitored utilizing calotest and other advanced measuring equipment. UNIQUE APPROACH. What takes place in the coating chamber is widely considered the most critical step in the coating process. However, if tools and parts are not properly prepared, coating quality can be severely compromised. At Guhring, we take the time to prepare each job properly. First, we clean each tool and part thoroughly in our special five-stage ultrasonic cleaning system. Second, we sort each job by tool and part size, geometry and material type to promote optimum coating uniformity and thickness. Properly cleaned and sorted, the tools and parts are then placed in the coating chamber. We monitor the coating process closely to ensure that neither the structural integrity nor geometry of the tools and parts is altered. In sum, Guhring s approach to coating combines high technology with personal attention to detail, resulting in a level of coating quality and service few can match.
