Collection: HSS Ground Flute

HSS ground flute drill bits are the precision grade for accurate, clean-cutting holes in metal, wood and plastic — fully ground flutes for tighter tolerance and a smoother cut than rolled bits.

Metric & imperial
Choose metric (1.0–13.0mm) or imperial fractional (1/16"–1/2") sizes below, as single bits or trade packs.

For heavy-duty general drilling choose roll forged; for stainless and hardened steel choose cobalt.
