Taper shank drill bit with 1 11/16 in size and 118-degree point for high-speed steel drilling
This taper-shank drill bit fits a #5 Morse taper holder and is made from high-speed steel with a black oxide finish. It is intended for machine-shop and maintenance crews who need a large-diameter cutting tool for general-purpose drilling in ferrous and non-ferrous metals.
The 118-degree point angle provides reliable centering and chip evacuation in normal drilling operations. Black oxide coating reduces friction and resists corrosion during extended use. Heat generated in the cut is managed by the high-speed steel substrate and standard cutting-fluid practices. Noise and power draw follow the machine tool and feed rate selected by the operator.

Clean the #5MT taper and spindle bore thoroughly, insert the 1 11/16 in drill bit, then seat it with a firm mallet tap on the tang; the step many skip is removing all oil or debris so the Morse taper locks securely.
Resharpen the 118 degree conventional point when cutting slows or chips turn blue; replace the black oxide drill bit once the flutes wear past the web or the 1 11/16 in diameter no longer meets tolerance.
