Cle-Line C20756 118 Degree 31/32 in Silver & Deming Drill 1/2 Reduced Shank

Cle-Line C20756 31/32 in Drill

The Cle-Line C20756 is a silver and deming drill bit designed for general-purpose drilling tasks. It features a 31/32 inch cutting diameter with a 118 degree point angle for efficient material penetration. The bit is constructed from high speed steel with a black oxide finish to resist wear and corrosion. Its 1/2 inch reduced shank allows compatibility with standard drill chucks.

1/2 Inch Reduced Shank Interface

The 1/2 inch reduced shank limits use to drill chucks that accommodate this specific shank size. Larger chucks will not grip the shank securely without an adapter sleeve. The shank diameter restricts the maximum torque that can be transmitted compared to full-shank bits of the same cutting diameter. Users must ensure their drill chuck capacity matches the 1/2 inch shank specification.

31/32 Inch Capacity Headroom

This bit comfortably handles drilling holes at its nominal 31/32 inch diameter in mild steel, aluminium and similar materials. It runs out when the workpiece hardness exceeds the capability of high speed steel or when hole depths require flute lengths beyond the standard bit design. The 118 degree point is not optimised for very hard alloys or abrasive composites.
