Collection: HSS Drill Bits

HSS drill bits are the everyday workhorse for drilling metal, wood and plastic — high-speed steel twist drills that keep a sharp cutting edge and clear swarf cleanly.

Choose your grade
Roll forged is the economical general-purpose bit, ground flute gives a cleaner and more accurate cut, and cobalt (M35, 5% cobalt) stands up to stainless steel and other hard, heat-generating metals.

Standard, stub and long
Jobber length covers most jobs, stub drills are shorter and more rigid for accurate starts in thin or hard material, and long series reach deeper holes.

Sizes
Metric from 1.0mm to 13.0mm plus imperial fractional sizes, available as single bits or in trade packs.

Uses
Steel, cast iron, brass, copper, aluminium, plastics and wood; choose cobalt for stainless and hardened steel.

Also known as HSS twist drills, jobber drills, engineer's drill bits or metal drill bits.
