Cle-Line C21101 11pc 1/16-3/8x1/32 HSS 118° Jobber Drill Bit Set

Cle-Line 11-Piece Jobber Drill Bit Set

This Cle-Line C21101 set contains 11 high-speed steel drill bits ranging from 1/16 inch to 3/8 inch in 1/32 inch increments. The 118-degree point angle suits general-purpose drilling in metal, wood and plastic. Black oxide finish adds corrosion resistance and reduces chip welding during use.

Practical limits of the 118-degree point angle

The 118-degree point is optimised for general-purpose work rather than specialised materials. It may walk on hardened steel or require a centre punch for accurate starts. Black oxide finish helps with lubricity but does not replace cutting fluid in deep holes or high-speed production drilling.

Upgrading from basic carbon-steel bits

This set replaces low-cost carbon-steel bits that dull quickly in metal. The high-speed steel construction holds an edge longer and tolerates higher cutting temperatures. The jump is worth it for workshops that drill steel regularly and need consistent hole quality across multiple diameters.
