Description

Dormer Pramet A120 21.00 mm HSS straight shank stub drill (DIN 1897) is a compact, reliable drilling tool designed for metalworking professionals and serious hobbyists. With a 21 mm diameter and a straight shank, it offers rigid, precise drilling suitable for both handheld use and machine setups.

Featuring an 118-degree split point, this drill bit starts holes cleanly and centers itself, reducing wandering and the effort required to begin cutting. The steam oxide finish helps prevent workpiece material from sticking to the edge, promoting smoother cuts and easier chip evacuation. Built from premium high-speed steel, it delivers dependable performance across a range of materials, including steel, aluminum, and stainless steel.

  • 118° Split Point for Easy, Self-Centered Starts: Guides the drill with minimal wandering and lowers the push force needed to begin each hole, improving first-hole accuracy.
  • Steam Oxide Finish for Reduced Sticking: Minimizes material buildup on the cutting edge for smoother drilling and consistent hole quality.
  • Premium HSS for Versatility: Robust high-speed steel handles drilling in steel, aluminum, and stainless steel with reliable, long-lasting performance.

Designed to fit a wide range of chucks and machines thanks to its straight shank and DIN 1897 specification, this drill bit supports efficient workflows, fewer reworks, and high-quality results across demanding metalworking tasks.
