Dormer Pramet A920 3/8 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK STUB DRILL DIN/ANSI

The Dormer Pramet A920 3/8 Inch HSS-E Straight Shank Stub Drill is a versatile, high‑performance drill bit designed for multi‑material metalworking. With a DIN/ANSI straight shank and a 3/8" diameter, it’s built to deliver clean, accurate holes across steel, aluminium, and stainless steel, whether you’re in a workshop, on a job site, or feeding a production line.

A 130° point provides self‑centering and reduces the push force needed to start holes, helping you achieve precise entry from the first cut. The bright finish minimizes material adhesion to the cutting edge, promoting smoother cuts and easier chip flow. The parabolic flute design enhances chip evacuation and enables deeper holes in a single pass, boosting productivity. Crafted from premium HSS‑E, it maintains high performance at speed and feed while delivering reliable hole tolerance (H10) across a range of common metals.
