HSS Ground Flute Jobber Drill Bits – Metric 1–13mm

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

Grade
Ground flute — machined (fully ground) flutes give better concentricity and a cleaner, more accurate hole, a step up from roll forged.

Sizes
Metric, 1.0mm to 13.0mm.

Construction
High-speed steel with ground flutes and a round shank, jobber length.

Standard
Manufactured to DIN 338.

Uses
Drilling steel, cast iron, brass, copper, aluminium, hardwood, softwood and plastics — where a clean, accurate hole matters.

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

Choose your size and quantity above — buy single bits or in trade packs.

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