13 Blind Hole MolyGlide 4 MolyGlide MOLYGLIDE Coating for Tapping Guhring has developed a new Molybdenum Disulfide-based coating that acts as a gliding agent greatly reducing surface-to-surface friction in machining applications. MolyGlide is a non-stick coating that is perfect for tapping soft gummy materials (aluminum, mild steel, copper, etc.) due to its inherent ability to resist chip welding. MolyGlide acts as a self lubricating agent that stays with the cutting tool. In applications that tend to run at near dry cutting conditions, MolyGlide can extend tool life dramatically. Reduced chip welding can also lead to improved thread surface finish and quality. Guhring offers MolyGlide coated standard taps in both the yellow and black ring styles. In addition, Guhring s Coating Division can apply MolyGlide to any cutting tool upon request. This coating is a soft coating that can be applied to a bright finish tool or on top of an exisitng hard coating such as or TiCN.

This provides our customers with a wider range of holding options and shank designs. For example, many customers prefer the added strength of the oversize shank geometry of the style to the standard straight shank of the or styles. Some customers need the added length of a DIN standard tap while others are comfortable with the conventional dimensions of the standard. Guhring s expansive tap offering provides the broadest range of holding options for maximum flexibilty.

Typical manufacturing prints will call for a 68 to 75 percent-of-thread for the finished part, but in many cases the machinist has a wider latitude of percent-of-thread to fall within. Be aware that increasing the percent-ofthread will increase the strength of the thread but will in many cases decrease the life of the tool. For example, increasing the percent-of-thread from 75% to 100% will increase the strength of that thread by approximately 5%but it will require 3 times the amount of torque to produce the same thread. In general, try to keep the percent-of-thread to the low end of the part tolerance. When trying to find the right tap drill size, remember that Guhring has the widest array of standard off-the-shelf drill diameters in the industry to provide you with the most options. 20 Certain DIN style taps are non-stock items in the USA.

This unique coating combines layers of and TiAIN coating to produce a unique substrate that can withstand cutting temperatures over 147F which is some 30F higher than standard coating. FIREX also imparts a 90+Rc surface hardness to the tool to withstand even the most abrasive wear applications. Cast iron is an excellent application for this revolutionary coating and Guhring offers two series of standard FIREX coated white ring taps for extended tool life. FIREX beats the heat 38 Certain DIN style taps are non-stock items in the USA. Allow 5-7 working days for delivery on non-stock items.

47 X Grooves X Grooves X Grooves ~ X Grooves Guhring s New Form Tap Profile Conventional form taps, produced with standard grinding processes, show traces of microscopic grinding marks on the surface of the tool and thread profile. These grinding marks can have a negative effect on the reaction of the tool and the material to be reformed. Friction between the two surfaces can increase, as well as the heat generated in association with the forming process. Additionally, the tap can require more torque to operate, and lastly, these grinding marks will increase the wear on the tool by encouraging material build-up. Thanks to a special manufacturing process to improve the surface finish of our taps, Guhring s new form taps no longer possess these grind marks. Guhring form taps have an exceptional surface finish quality few manufacturers offer. For the end user, this new manufacturing process provides longer tool life and increased cutting speeds. Tool life can be improved by considerably depending on the material to be machined and the application conditions. A 100% increase in tool life is not unusual Optimized surface of a Guhring Profile Fluteless Tap Surface of a Conventional Fluteless Tap Forming...The Future! Guhring s Tap Catalog 2007 includes two new fluteless tap generations. A. New AICrN Based hard coating, called P-coating in reference to Guhring s Profile-fluteless tap. The coating is ideally suited for cold forming, the process used when producing internal threads through thread forming. [ Refer to page 7 - Series # 1723, # 1719, # 1721, # 1717 ] B. New DK255F with the universal -coating, DK255F is harder and offers improved wear resistance compared with the carbide DK460UF used previously for fluteless taps. RESULTS: Increase in tool life resulting in a more economic production. The diameter range for metric threads has been increased to M20. Diameters MF 12x1 to MF 24x1.5 have also been included in the metric fine threads range.

Manufacturing our own carbide in-house gives us greater control over the entire tool production process from substrate procurement to the finished tool. GUHRING S carbide manufacturing facilities feature the most advanced equipment available, including both cold isostatic wetbag and drybag presses, state-of-the-art computer-controlled sinter-hipping furnaces, EDAX-system electron scan microscopes, as well as specialized hardness, toughness and bending strength testing equipment. Strict monitoring, handling and inspection systems employed during substrate production contribute significantly to the ultimate quality and performance of GUHRING carbide tooling. From the K- and P-grade families, GUHRING s carbide offering runs the gamut of substrate performance characteristics, including hardness, bending strength and heat resistance. This diversity of choice provides different substrate options for different holemaking challenges. High Performance Thin-Film Coatings 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%! As a cutting tool manufacturer, Guhring offers a level of technical expertise without equal in the industry. Guhring was the first to introduce 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 s stable of hard coatings currently totals five, including our proprietary -TiAlN multilayer coating FIREX, our new super-hard, super-tough TiAlN coating, plus our special MolyGlide soft coating, which impregnates its lubricity right into the tool and can be applied to both bright and hard coated surfaces.
