HSS Blacksmith Drill Bits – Reduced Shank, Metric 13.5–26mm

HSS blacksmith drill bits let you drill large-diameter holes in metal with an ordinary drill — big high-speed steel twist drills with a reduced shank that fits a standard 13mm chuck, so you don't need a specialist machine.

Reduced shank
The shank is turned down to 13mm (1/2") so diameters up to 26mm still fit a standard drill chuck.

Construction
High-speed steel with a ground flute for smooth, accurate cutting.

Sizes
Metric, 13.5mm to 26.0mm.

Uses
Drilling larger holes in steel, cast iron, brass, aluminium and other metals, and in wood and plastics.

For diameters up to 13mm, our jobber-length HSS drill bits cover the standard range.

Also known as reduced shank drill bits, blacksmith drills, large diameter HSS drill bits, 1/2" shank drills or blacksmiths bits.
