M35 and M42 is a development of M2 and contains 5% or 8% Cobalt which gives improved hardness, wear resistance and red hardness. It may be used when cutting higher strength materials.
Feature:
- Made of high quality & super tough high speed steel with multi-cut geometry for ply-cutting and lower friction to reach better
endurance and less breakage;
- Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals;
- Optimized cutting edge geometry for increased cutting performances and reduced cutting forces;
- The effective cutting angles are designed for universal use in various sorts of steel;
- Improved removal of chips thanks to U-shaped recesses. The specific geometry of the recess reduces the thermal load on the HSS
core drill as the heat created in cutting is removed with the chips to a very great extent;
- Reduction of the friction between the HSS core drill and the workpiece thanks to optimised spiral-shaped guide chamfers;
