Common questions
What is a step drill used for?
Cutting clean holes in thin material like sheet metal, in a range of sizes with one bit. Each step cuts a larger diameter as you push the bit through.
M2 HSS or M35 cobalt?
Most are M2 HSS. Three are M35 cobalt with a TiAlN coating, which suits tougher metals and heavier use. Check the product page for the exact material.
Can I use a step drill in an impact driver?
Yes, if it is the 1/4" hex impact-ready version. Nine bits in this collection are. Check the shank before you buy.
