Cle-Line C20736 Reduced Shank Drill Bit
This Cle-Line C20736 drill bit features a 1/2 inch reduced shank designed for use in chucks with smaller capacity. It suits machinists and maintenance technicians who need to drill larger holes without upgrading their drill press or hand drill. The 118 degree point angle provides a standard cutting profile for general purpose metalworking tasks. New condition ensures full tool life from the first cut.
118 Degree Point Angle Cutting Limits
The 118 degree point angle is optimised for general purpose drilling in mild steel, cast iron and non-ferrous metals. It may walk on hardened materials or curved surfaces without a centre punch mark. The high speed steel construction resists heat during continuous cutting but requires appropriate cutting fluid to prevent premature dulling. This geometry is not specialised for deep hole drilling or high precision hole finishing.
Black Oxide Finish and Shank Practicality
The black oxide finish adds corrosion resistance and helps retain lubricant during operation. The 1/2 inch reduced shank allows compatibility with standard 1/2 inch drill chucks while the cutting diameter exceeds that capacity. Users must ensure the shank is fully seated and tightened to prevent slippage under load. The straight shank design suits keyed and keyless three jaw chucks alike.

Questions about this item
Should I choose the 9/16 inch size or look for a different diameter?
The drill bit is a single 9/16 inch size with a 1/2 inch reduced shank, so select it when that exact hole diameter is required.
What does the 118-degree point angle do for me in a real job?
The 118-degree point is a general-purpose geometry that centres quickly in mild steel and aluminium, giving reliable chip clearance without aggressive cutting pressure.
How does the 1/2 inch reduced shank affect what chucks I can use?
The 1/2 inch reduced shank fits standard 1/2 inch drill chucks, letting you run a 9/16 inch bit on a drill that cannot accept a full-size shank.
