Reduced-Shank Drill Bit for Large Holes
The Cle-Line C20762 is a Silver & Deming drill bit designed for drilling large-diameter holes with a standard 1/2 inch reduced shank. It features a 118 degree point angle suited for general-purpose drilling in metal. The bit is manufactured from HAWA high-speed steel with a black oxide finish for durability.
Suitable for Machinists Using Standard Chucks
This bit suits machinists and maintenance technicians who need to drill 1 5/16 inch holes using a drill press or heavy-duty hand drill with a 1/2 inch chuck capacity. It is not for users requiring a full-size shank for maximum rigidity in heavy production. Buyers needing smaller step sizes or different point geometries for specialised alloys should look at other tooling.
1 5/16 Inch Capacity with 1/2 Inch Shank
The tool comfortably handles drilling at its full 1 5/16 inch diameter in mild steel and similar materials where the 118 degree point provides reliable centring. Headroom is limited by the reduced shank diameter, which restricts torque transmission compared to a full-shank bit. The high-speed steel construction wears faster than cobalt or carbide alternatives in abrasive or high-hardness workpieces.

Questions about this item
What size drill chuck do I need to fit the 1/2 reduced shank?
The bit has a 1/2 reduced shank, so a chuck that opens to at least 1/2 inch will hold it securely.
Does the 118 degree point angle suit the same jobs as my older 118 degree bits?
Yes, the 118 degree point angle is a standard general-purpose geometry that matches other 118 degree bits you may already use.
How can I confirm the black oxide finish is intact after installation?
Inspect the flutes and shank; the machining black oxide coating should appear as an even dark surface without bare steel showing.
