Maximum precision 

The ground HSS twist drill drills in metal with maximum precision. The self-centring drill point with cross-grinding and a point angle of 135 degrees enables perfect centring without wandering.

It is suitable for drilling holes in alloy and non-alloy steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics.

It is used with drill stands and drill screwdrivers. The ground HSS twist drill is manufactured according to DIN 338. 

It belongs to drill type N (small side rake angle) with drill point 135 degrees and diameter tolerance h8. 
Cylindrical shank is suitable for gear rim drill chucks.
