Dormer A-130 HSS Taper Shank Drill Bit

HIGHLIGHTS:

We sell only Original Dormer cutting tools — trusted worldwide for their precision, durability, and consistent manufacturing quality. The Dormer HSS Taper Shank Drill Bit (A-130) is a taper shank drill designed for general purpose applications up to 4xD, with a design that minimizes thrust requirements without compromising strength. The A-130 is especially suited for machine use, particularly for column drilling machines.

Manufactured to the DIN 345 standard, the A-130 features a right-hand spiral, a 118° point angle, and a steam tempered finish. Accurately ground from high-quality high speed steel, this drill bit is a robust all-rounder suitable for steel, stainless steel, cast iron, titanium, nickel, copper, aluminum, magnesium, synthetic materials, hard materials, and graphite. The steam relieving treatment results in better retention of cutting oil during drilling operations.

The taper shank is a Morse Taper design (size varies by diameter) that seats securely and accurately into a compatible machine spindle without the need for a chuck, providing strong, reliable torque transmission for larger-diameter holes drilled on column drilling machines and other taper-compatible machine tools. Available in a wide range of imperial sizes, the A-130 series gives machinists and fabricators the flexibility to match the correct cutter diameter and taper size to their specific drilling application.
