Product Specification

21/32" SILVER & DEMING HSS DRILL BIT

Benchmark Abrasives 21/32" Silver & Deming HSS Drill Bits are ideal for drilling steel, stainless steel, cast iron, titanium, manganese, and other tough materials. They are precision ground from one solid piece of heat-treated high speed and have a 135-degree split point to eliminate wobbling. 

Silver and Deming drill bits are large size bits with reduced shanks that are ideal for situations where a bit diameter is greater than the capacity of a drill chuck. This Silver and Deming drill bit is also known as a reduced-shank drill bit. The HSS drill bits provide good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials. Oxide coating of these bits prevents chip building, galling, and welding on the workpiece. Its black-gold surface treatment holds lubricant for smoother, longer drilling. It is ideal for drilling steel, stainless steel, cast iron, titanium, manganese, and other tough materials.

Lucy X. ★★★★★

Came home and had to drill into stainless steel right away—this bit made it look easy. The 21/32" size cut clean with barely any wandering, and the HSS tip held up through the whole job.

Sophia ★★★★★

This bit cut through a piece of steel bar stock without any binding or need for excessive pressure. The shank fits perfectly in my drill chuck and the finish looks clean.

Samuel ★★★★★

I needed to drill several holes in stainless steel for a bracket, and this bit went through without any chatter or binding. The reduced shank made it easy to chuck into my standard drill press.
