Collection: HSS Roll Forged

HSS roll forged drill bits are the tough, economical general-purpose grade for drilling metal, wood and plastic — high-speed steel twist drills with a rolled flute for strength.

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

For a cleaner, more accurate cut choose ground flute; for stainless and hardened steel choose cobalt.
