DIMENSIONS - HSS annular drill bit with Outside Diameter 11/16 inch with 1 inch cutting depth.
APPLICATION - Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals.
MATERIAL - 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.
FEATURES - 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.
It has cutting edges in every blade,so in very short time to complete the drilling operation and get cross holes.
3/4 Inch Weldon Shank fit into a majority of magnetic drills.
