The anufacture of highly accurate sall diaeter holes requires axiu quality and is one of the ost deanding drilling operations. For these tasks and for every user, Guhring s coprehensive standard range includes the optial icro-precision drill. 2

HSS-E-PM icro-precision drills Guhring s icro-precision drills in highly efficient powder etallurgical HSS-E steel excel with a very high wearresistance, high toughness and cutting edge stability

3 HSS-E-PM icro-precision drills Guhring s icro-precision drills in highly efficient powder etallurgical HSS-E steel excel with a very high wearresistance, high toughness and cutting edge stability that is especially iportant with difficult, less rigid achining conditions. The powder etallurgical produced HSS-E steel features a very hoogeneous structure having a positive effect on the consistently high perforance capability of the icro-precision drills. HSS-E-PM icro-precision drills are hence suitable, for exaple, for application on ulti-spindle achines, on achines with speed liitations or for the anufacture of sall and average batch sizes as here they offer high quality with an optial price-perforance ratio. For higher deands on tool life and cutting paraeters Guhring provides HSS-E-PM icro-precision in the standard range also with Ti-coating. Even for special applications where left-hand cutting drilling tools are required Guhring can offer a standard solution. Solid carbide icro-precision drills Guhring s solid carbide icro-precision drills without internal cooling cover a coprehensive diaeter range fro 0.1 to 3.0. With solid carbide icro-precision drills it is possible to achieve higher cutting paraeters and longer tool life when achining conditions are ore stable and achines are ore powerful copared to HSS-E-PM icro-precision drills. The reason for this is the use of ultra-fine carbide that features a very high hardness, heat-resistance and wearresistance and akes the enorous perforance capabilities of solid carbide icro-precision drills possible. Solid carbide icro-precision drills ExclusiveLine also with internal cooling Solid carbide ExclusiveLine icro-precision drills, available with or without coolant ducts, ake high-perforance achining in ost aterials possible. Micro-precision drills deonstrate their full perforance potential in volue production of large batch sizes with rigid achine conditions, high achine perforance and spindle speeds. The 2-facet point grind per cutting edge with ground cutting edge honing perits high cutting values as well as optial chip breaking. Chip spaces with special flute geoetry evacuate the chips safely fro the hole. For drilling depths to 4xD and 7xD, solid carbide icro-precision drills without internal cooling are available in the diaeter range fro 0.5 to 3.0. Especially for the achining of stainless steels and special alloys as well as deep holes 5xD, 8xD an5xd solid carbide icro-precision drills with internal cooling prove their perforance capability. Thanks to the optiised tool geoetry pecking is not necessary with Guhring s solid carbide icroprecision drills up to 15xD. The tools are designed so that solid carbide icro-precision drills up to 4xD without internal cooling and up to 5xD with internal cooling are optially suited as pilot drill for the 15xD icro-precision drill with internal cooling. Special solutions to custoer requireents In addition to the standard icro-precision entioned, Guhring also supplies HSS-E-PM and solid carbide icro-precision drills as special tools at custoer request. They include: interediate diensions to the standard range stepped tools for stepped holes or countersink holes special lengths up to 30xD drilling depth different shank variants alternative coatings 3
