FAQ's: Reduced Shank Drills

Yes — HSS reduced shank bits work well in wood and plastic, but ensure proper feed rates to avoid overheating or chipping.

Common in construction, fabrication, maintenance, automotive repair, and industrial metalworking.

Yes — options include black oxide for corrosion resistance, TiN (titanium nitride) for wear resistance, and uncoated for general use.

No — they’re not designed for the percussive action of impact drivers. Use in drills and drill presses.

Cobalt bits can last 2–4 times longer in hard metals compared to HSS, assuming proper use and cooling.

Yes, especially in metals. Cutting oil reduces heat, prevents premature dulling, and extends bit life.

It depends on the bit — reduced shank designs can go up to 1-1/2" cutting diameter for a 1/2" shank.

Yes — they can be sharpened on a bench grinder or with a drill bit sharpener, following the correct cutting angle.

Cobalt is harder and more heat resistant but slightly more brittle than HSS, so avoid side pressure to prevent chipping.

Yes — common reduced shank sizes include 1/2" and 3/8" shanks, with cutting diameters much larger than the shank.

Yes — they’re designed to fit standard drill chucks, including handheld drills, drill presses, and magnetic drills.

For mild steel, aluminum, and wood, HSS is economical and effective. For stainless steel, hardened steel, and other high-tensile metals, cobalt will last longer and cut more efficiently.

HSS bits are made from high-speed steel for general-purpose drilling in softer metals, wood, and plastics. Cobalt bits contain 5–8% cobalt for added hardness and heat resistance, making them better for stainless steel and other hard alloys.

It lets you drill larger holes without needing a drill with a bigger chuck size — for example, a 3/4" bit with a 1/2" shank fits a standard 1/2" drill.

A reduced shank drill bit has a smaller shank diameter than the cutting diameter, allowing large-diameter holes to be drilled in drills with smaller chucks.
