Product Specification

31/32" SILVER & DEMING HSS DRILL BIT

Benchmark Abrasives 31/32" 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.

  • We suggest using a drill press as opposed to a drill with our silver and demming bits.  A drill can be tricky to ensure straight drilled holes.  When using a handheld drill, invest in a jig to ensure your holes are straight

Sophia W. ★★★★★

The 1/2" shank on this thing actually fits my old drill press chuck without slipping, which was my main worry. Cut through a plate of mild steel way faster than the cheap bits I had before, and the tip still looks sharp after a dozen holes.

Ruby ★★★★★

Bored out a 31/32" hole through half-inch stainless plate and it cut clean without chattering or wandering. The HSS holds an edge way better than the cheap bits I've burned through before.

Ryan X. ★★★★★

Chucked this in my drill press to open up some existing holes and it cut through without chattering at all. The 1/2" shank fits a standard chuck fine, and the HSS held its edge through maybe a dozen holes. Good bit for the money.
