Cle-Line C20760 1 3/16 in HSS 118° drill bit

Cle-Line C20760 Reduced Shank Drill Bit

The Cle-Line C20760 is a high-speed steel drill bit with a 1 3/16 inch diameter and a 118-degree point angle. It features a black oxide finish for corrosion resistance and reduced friction during operation. This accessory targets machinists and maintenance technicians drilling larger holes in metal stock. The reduced shank design allows use with standard 1/2 inch drill chucks.

Practical Limits of the 118-Degree Point Angle

The 118-degree point angle is a general-purpose geometry suited for mild steel, cast iron and non-ferrous metals. It tends to walk on hard or smooth surfaces without a centre punch mark. The standard web thickness requires higher feed pressure than split-point designs. High-speed steel loses temper faster than cobalt alloys when drilling stainless steel or hardened materials. The black oxide finish helps retain coolant but does not eliminate heat buildup in deep holes.
