What This Drill Bit Does

The Cle-Line C17086 is a Silver & Deming drill bit with a 118-degree point angle designed for general-purpose metal cutting. It targets machinists and maintenance technicians who need a single bit to enlarge existing holes in steel, cast iron and non-ferrous alloys using a standard 1/2-inch chuck.

Compatibility Check Before Ordering

Verify that your drill press or hand drill accepts a 1/2-inch reduced shank and can deliver the low speed and steady feed this geometry requires. Confirm the workpiece material suits high-speed steel and that your setup provides adequate coolant or lubrication to prevent premature wear.

What the Finish Changes

The black-and-gold surface treatment reduces friction and improves chip evacuation compared with an uncoated high-speed steel bit. This coating extends tool life in repetitive drilling tasks and helps maintain hole accuracy when working through thicker sections.
