Industrial HSS Cobalt Annular Cutters Metal Drilling Tool

M35 is a development of M2 and contains 5% 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 work piece thanks to optimized spiral-shaped guide chamfers.
