HSS Annular Cutter: M2AL High Speed Steel

TCT Annular Cutter: Tungsten carbide tip+45# Steel

Weldon Shank   (Universal Shank and Fein Shank are available)

HSS Annular Cutter:

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.Weldon shank fit into a majority of magnetic drills.

TCT Annular Cutter:

1.Tungsten carbide tipped annular cutters combine extreme hardness and durability with a wide range of possible applications in a convincing product.

2.Unique tooth geometry, cutting teeth specially grinding by CNC Machine to assure all of teeth in same level,allows for better centering and faster cutting;

3.Thin wall design enables cutters to cut faster and more efficiently by removing less material during drilling;

4.Shorter flute design allows for chips to fall freely from cutter;

5.Universal shank cutter is designed for use in any magnetic drill press.
