Walter highlights features of DB133 Supreme drills
The new DB133 drills, with their 140° point geometry, are available in diameter range from 1/32-5/64 in. and 0.5 to 2.95 mm. Length to diameter ratios (L/D) of 5, 8 and 12 x Dc are standard.

The Flex drills are available in steps of one hundredth millimeter for drilling depths of 50 x D, as well as the "shorter" lengths of 20 x D and 30 x D.
A Dormer-branded tool designed for stainless steel is the Force M drill, which has a micrograin carbide substrate and a multilayer TiAlN coating. The drill has an S-shape, modified four-facet, split-point geometry to reduce cutting pressure with honed corners and cutting edges so they do not chip when starting a hole.
Video demonstrates WTX-HFDS Solid Carbide Drills with applications including grey cast iron with spheroidal graphite and at tolerances of H7. The unique four-flute design of the WTX enables extremely high feeds in steel processing with quick chip removal. The distribution of force to four cutting edges, four continuous spiral-through coolant holes and new CERATIZIT Dragonskin Coating all result in a longer tool life.
