53/64 inch Reduced Shank Drill Bit
The Cle-Line C17051 is a Silver & Deming drill bit with a 53/64 inch cutting diameter and a 1/2 inch reduced shank. It is designed for machinists and maintenance technicians who need to drill large holes using a standard 1/2 inch capacity drill chuck. The 118 degree point angle suits general-purpose drilling in a variety of materials.
High Speed Steel Construction
Manufactured from high speed steel, the bit offers the hardness and heat resistance required for machining metal workpieces. The black and gold finish helps identify the tool and provides a degree of surface protection during normal workshop use. No specific thermal, noise or power draw data applies to this unpowered accessory.
Compatibility With 1/2 Inch Chucks
The reduced shank allows the large 53/64 inch drill body to be secured in any drill press or hand drill equipped with a standard 1/2 inch chuck. This eliminates the need for a larger capacity spindle or specialised tool holder. Buyers who require a drill bit with a shank diameter matching the full cutting diameter cannot use this design.

Questions about this item
How do I install the 1/2 reduced shank on my drill press chuck without it slipping?
Open the chuck fully, insert the shank until the flutes begin, then tighten firmly by hand before using the chuck key; the reduced diameter means less contact area, so confirm zero run-out before drilling.
When will the 118-degree high-speed steel cutting edges need resharpening or replacement?
Resharpen when feed force increases noticeably or holes become oversized; high-speed steel can be reground several times until the flute length shortens below the 53/64 diameter.
What is the first limitation I will hit during sustained drilling with the 53/64 bit?
Heat buildup at the 118-degree point softens the high-speed steel fastest; use cutting fluid and reduce RPM to delay loss of edge hardness.
