Description
Product details
High stability and fracture resistance, made of HSS steel blank
Accurate size drill holes, because the drill bit as a whole is cut out of a hardened pin
The special split point diamond shape means pre-centering force does not need to be exerted on the workpiece
The point angle is 130°. This i.c.m, the split point diamond shape ensures that the drill is stable and makes round holes in thin material
The drill does not crash because the outer diameter gradually becomes smaller from the tip to the shank (rejuvenation)
High stability and reduced vibration, because the diameter of the core is increasing in the direction of the shaft
The entire working length of the drill is regrindable
Application areas
Suitable for construction steel to a tensile strength of 1000 N/mm°, cast iron, non-ferrous metals, in hand and pillar drills
Hints
Apply Berner's Drilling and Cutting Oil (Part No. B911371) to cool while drilling
