For drilling of long and short-chipping
materials such as structural and case
hardened steels, cast steels, heat-treatable
steels and alloyed steels with a
tensile strength of up to 1200 N/mm 2 ,
including carbon steels, bronze, cast iron
and high-alloyed AlSi-alloys.
For drilling depths up to ≤ 7 x D.
Point grinding: relieved cone with
secondary flank
Point angle: 140˚
Web thinned: TS-special

high alignment accuracy with tight tolerance
and excellent surface finish. Excellent
self-centering qualities as well as
producing short chips thanks to a concave
cutting point geometry with special
point grind and web thinning.
