Description

The Dormer Pramet A100 12.40 mm HSS Straight Shank Jobber Drill (DIN 338) is a reliable, general‑purpose tool for metalworking across steel, aluminium, and stainless steel. Its 118‑degree conventional point starts cuts cleanly and is easy to re-sharpen, helping you maintain precise holes with minimal downtime. The straight shank design fits both hand-held drills and machine tool holders, making it a versatile addition to any workshop.

118° conventional point with easy re-grind: Delivers reliable starts and clean holes, and is simple to re-sharpen to extend tool life between changes.
Steam oxide finish for reduced sticking: Minimizes built‑up edge and improves chip flow for cooler, more consistent cutting across materials.
Silver ring authenticity and precise diameter: Clearly marks genuine Dormer Pramet and confirms the 12.40 mm size, reducing setup errors and ensuring accurate hole sizing.

This drill supports dependable, repeatable results in professional and hobby projects alike. The combination of premium HSS, robust point geometry, and the steam oxide finish delivers smoother starts, less material adhesion, and longer bit life, while the diameter indication and DIN 338 compatibility help you keep workflows moving with confidence.
