Description
- For drilling low alloy steel (R<750N/mm²) to hard treated alloy steel (R>950N/mm²) as well as stainless steels.
An increase in cobalt content allows greater resistance to drill deformation.
It allows the drilling of hard and stainless steels that require sharpening with a lot of cutting throughout the drilling.
Up to 3 times more holes drilled than a standard HSS drill.
Auto Centering split point sharpening for effective attack in the material without prior pointing.
HSS steel hardness index HRC 66/67.
Tail reduced to 13 mm.
