Dormer A-130 HS Taper Shank Drill Bit (Metric Sizes, 14mm – 50mm)

HIGHLIGHTS:

We sell only Original Dormer cutting tools — trusted worldwide for their precision, durability, and consistent manufacturing quality. The Dormer A-130 HS Taper Shank Drill Bit is a high-speed steel jobber-length drill with a Morse taper shank, designed to be held directly in a machine spindle without a chuck — ideal for drilling larger diameters on drill presses and machine tools.

The A-130 features a 118° conventional (thinned) point angle for a strong, easy-to-regrind point, along with a steam-tempered (blue oxide) finish that improves wear resistance and prevents material from sticking to the cutting edge. Its design allows drilling up to 4× the bit diameter with minimized thrust requirements, without compromising strength.

Manufactured to DIN 345 standards with a right-hand spiral, the A-130 is suitable for drilling steel (up to 1,000 N/mm² tensile strength), cast steel, grey cast iron, malleable cast iron, nickel brass, and graphite — making it a dependable choice for machine shops and industrial workshops working with larger hole diameters.
