Cle-Line C20740 Reduced Shank Drill Bit

The Cle-Line C20740 is a Silver & Deming drill bit designed for general-purpose drilling tasks where a 1/2 inch reduced shank fits the chuck. It suits maintenance technicians and metalworkers who need a reliable high-speed steel bit for workshop or job-site use.

118 Degree Point Angle for General Drilling

The 118 degree point angle determines how the bit centres and cuts in metal, wood or plastic without a pilot hole. This angle is the standard choice for handheld drilling in mild steel and softer materials, making it the single specification that confirms suitability for everyday bench work.

Straightforward Chuck Fit and Common Issues

The 1/2 inch reduced shank seats directly in standard drill chucks, so installation is a simple matter of tightening the jaws securely. The most frequent problem is the bit spinning in the chuck under heavy feed pressure; ensuring the jaws grip the flat sections of the shank prevents slippage and maintains drilling accuracy.

Questions about this item

What does the 118-degree point angle mean when drilling?

The 118-degree point angle is a general-purpose geometry that centers easily and works well in mild steel, aluminium and wood without specialised tooling.

How does the 1/2-inch reduced shank affect chuck compatibility?

The reduced shank lets the 5/8-inch drill bit fit any standard 1/2-inch three-jaw chuck, so it works on most bench presses and heavy-duty hand drills.

What clearance is needed to mount this bit in a drill press?

The bit has a straight 1/2-inch shank with no flats or tang, so it requires a standard three-jaw chuck opening of at least 1/2 inch and enough quill travel for the full bit length.
