For certain materials a coating is required, as the successful application of gun drills with a bright surface finish cannot be guaranteed. For coating definitions see Hartnerguide page 38/39. T TiN TiCN A AlTiN AlTiN nano The main advantage of two-fluted gun drills compared to single-fluted gun drills is the substantially higher feed rate that can be applied during the production of the hole. This is due to the design of the two-fluted gun drill, it has two cutting edges and two flutes. Holes can therefore be produced considerably faster. However, this increase in machining speed is combined with a reduction in hole accuracy. This is also a direct consequence of a drill design with two cutting edges. As the cutting edges are positioned opposite each other, there is less of a smoothing effect and less support in comparison to a single-fluted gun drill. For drilling depths 10 x D we recommend our TS Drill TS 0 GG, available ex stock and more cost-effective for these drilling depths than brazed gun drills. In addition, TS 0 GG does not require a pilot hole in most applications. The dimensions required to calculate the length for conventional machine tools head length * max. flute length per tool 40 x D, for larger drilling depths apply two tools.

30 Grinding equipment for single-fluted gun drills TBM 116 TBM 116 is a manually operated, universal grinding machine. Its compact design combined with Hartner s single-fluted gun drill grinding system and Hartner s double grinding wheel makes this a perfect unit to re-grind single-fluted gun drills. It is especially suitable for the re-grinding of a small to medium number of items of varying diameters and lengths. Furthermore, it also allows the fairly simple addition of transverse chip breakers to single-fluted gun drills as well as other modifications. Supplied items: Grinding machine with two high-powered light units as well as two 220 V sockets (grinding system and grinding wheel not included) Machine data: Input power requirements 380 V/50 Hz, Grinding wheel 2850 rev./min, Max. diameter of grinding whee50 mm TBV 116 The fixture is designed for the re-grinding of single-fluted gun drills in the diameter range from 3 mm to 30 mm. It is ideally suitable for standard and special point grinds. A minimum flute length is of no importance thanks to a short center sleeve. In addition, the fixture is supplied with a supporting bar for long tools. TBV 116 is therefore truely universal and can be applied on any commercial, manual tool grinding machine. For the use with TBV 116 we recommend our double grinding wheel DSS 125. Attention: Single-fluted gun drills have a flute spacing angle of 120 and can therefore not be clamped in a collet in a separate unit. You could possibly destroy the tool. TBV 216 The new TBV 216 universal grinding fixture for small diameter single-fluted gun drills from 1.0 to 6.0 mm and a maximum length of 350 mm is simple to handle and enables the regrinding or modifying of single-fluted gun drills in only four operations. Grinding is achieved with a 3-axis swivel mechansim, enabling the grinding of various point angles. It is possible to adjust and if necessary correct any angle individually. We recommend the application of our single grinding wheel ESS 125. Scope of delivery: - A set of guide bushes with the diameters 1.0 / 1.5 / 2.0 / 2.5 / 3.0 / 3.5 mm - Various adaptors - Centering microscope - Spotlight and magnifier 30

34 Technical section An introduction to the subject of deep hole drilling In the machining world, drilling depths of 10 x D and deeper are regarded as deep hole drilling operations, whereby smaller drilling depths can naturally also be produced with gun drills. Advantage is taken of the positive side effects, as for example good surface quality, low deviation from concentricity and optimised alignment accuracy. High pressure cooling - has become a matter of course. In recent years, internal cooling has established itself for all drilling tools. Coolants are now living up to their name and being supplied via coolant ducts to where they are urgently required. Considerable improvements in tool life and less breakages have been achieved by this measure for twist drills, taps etc. Every conventional machine tool currently on the market can be supplied with high pressure internal cooling and is therefore also suitable for deep hole drilling. The share of gun drills on machining centres, lathes etc. is forever gaining more importance. The process is therefore increasing in popularity in the machining world. All gun drills must have support for the pilot hole. Gun drills must never operate at full speed without support in the machine shop. Deep hole drilling on conventional machine tools Deep hole drilling is not a closed book, but can be mastered by anybody as long as certain conditions are adhered to. Recommended cutting rates for the application of Hartner gun drills can be found on the pages 38/39 for the individual types! Typical procedure with all gun drills on conventional machine tools: production of pilot hole (L = 3 x D, tolerance H8) enter at low revolutions, approx. 200 rev./min, feed rate approx. 500 mm/min. With tools for drilling depths in excess than 40 x D enter the pilot hole revolving in left hand direction. At cutting speeds higher than 120 m/min we recommend to advance to final speed in several steps. setting of coolant pressure and revolutions uninterrupted drilling to required drilling depth without wood pecking. When applying gun drills with increased lengthdiameter-ratio, we recommend machining with reduced cutting parameters (approx. 75% of the optimal cutting speed) up to a drilling depth of approx. 25 mm. switching off coolant supply after reaching required hole depth withdrawal in top gear with stationary spindle Application advice For drilling depths in excess than 40 x D we recommend the use of two or more gun drills, e. g. Ø 10 x 400 mm and Ø 9.95 x 800 mm. Gun drills for drilling depths of more than 40 x D should enter the pilot hole revolving in the left hand direction. When changing tools for drilling depths of more than 40 x D, the tool can be damped by switching on coolant supply for just one second. For machining of long-chipping materials we recommend the use of gun drills with polished flutes. Generally we recommend the use of soluble oil with a minimum oil content of 10 %. Single-fluted gun drills for long-chipping aluminium should be supplied with point grin80 and coolant chamber.

35 Technical section Basic tolerances* The application of single-fluted gun drills can achieve a lower basic tolerance, as the cutting forces at the cutting edge are absorbed by the guide pads, unlike twist drills where the slightest deviation of the two cutting edges causes a larger hole. Achievable tolerances Copper, nickel, zinc and their alloys Al-alloys (acc. to Si-content) normal conditions optimal conditions Alignment accuracy* Because brazed single-fluted gun drills always have the precision carbide head brazed on to a flexible tube, the tool achieves very accurate aligned holes remaining unaffected by possible concentricity errors. However, extreme material fluctuations and other influencing factors can impair the alignment accuracy Heat-treatable steels Cast rion Nitriding steels Stainless steels Structural steel Alignment in mm Case hardened steel Basic tolerance grade IT Drilling depth in mm Surface quality* The forces at the cutting edge are absorbed by the support bushes, which in return burnishes the surface. Lubrication between the guide pads and hole surface is therefore very important. The better the lubricant, the better the surface quality. Deviation from concentricity* When a hole is produced with, for example, a commercial twist drill, the quality of the point grind affects the concentricity of the hole. An imbalance of forces is created at the cutting edges. With gun drills, these cutting forces are absorbed by the guide pads, resulting in excellent concentricity.
