FAQ's: Reduced Shank Drills
Can I use a reduced shank drill bit for wood or plastic?
Yes — HSS reduced shank bits work well in wood and plastic, but ensure proper feed rates to avoid overheating or chipping.
What industries use reduced shank drill bits?
Common in construction, fabrication, maintenance, automotive repair, and industrial metalworking.
Are there coating options for reduced shank drills?
Yes — options include black oxide for corrosion resistance, TiN (titanium nitride) for wear resistance, and uncoated for general use.
Can reduced shank drill bits be used in impact drivers?
No — they’re not designed for the percussive action of impact drivers. Use in drills and drill presses.
What’s the lifespan difference between HSS and cobalt reduced shank bits?
Cobalt bits can last 2–4 times longer in hard metals compared to HSS, assuming proper use and cooling.
Do I need lubrication when drilling with reduced shank bits?
Yes, especially in metals. Cutting oil reduces heat, prevents premature dulling, and extends bit life.
What’s the maximum hole size I can drill with a reduced shank bit?
It depends on the bit — reduced shank designs can go up to 1-1/2" cutting diameter for a 1/2" shank.
Can you sharpen reduced shank drill bits?
Yes — they can be sharpened on a bench grinder or with a drill bit sharpener, following the correct cutting angle.
Are cobalt reduced shank bits more brittle?
Cobalt is harder and more heat resistant but slightly more brittle than HSS, so avoid side pressure to prevent chipping.
Do reduced shank drills come in different sizes?
Yes — common reduced shank sizes include 1/2" and 3/8" shanks, with cutting diameters much larger than the shank.
Can you use reduced shank drills in a hand drill?
Yes — they’re designed to fit standard drill chucks, including handheld drills, drill presses, and magnetic drills.
Which is better, HSS or cobalt reduced shank 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.
What’s the difference between HSS and cobalt reduced shank drill bits?
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.
Why use a reduced shank drill bit?
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.
What is a reduced shank drill bit?
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.
