Drilling
Extreme Drilling from Guhring
Designed for extreme drilling in steels, Guhring’s RT100 XF drill family delivers. The carbide grade developed for the RT100 XF balances hardness and toughness. Polished flutes improve chip evacuation, reducing machining temperature and protecting the cutting edges. The micro-geometry honing process ensures a uniform hone resulting in a stable and efficient cutting edge.
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.

Machining stainless steel for aerospace applications
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.
