Thread Shank HSS Hole Annular Broach Cutter Core Drill Bit

Thread Shank HSS Hole Annular Broach Cutter Core Drill Bit

Weldon Shank   (Universal Shank and Fein Shank are available)

1.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 ;

2.Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals;

3.Optimised cutting edge geometry for increased cutting performances and reduced cutting forces;

4.The effective cutting angles are designed for universal use in various sorts of steel;

5.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;

6.Reduction of the friction between the HSS core drill and the workpiece thanks to optimised spiral-shaped guide chamfers;

7.M18*6/P1.5 thread shank. Suitable on Fein magnetic drill machine
