Designed for professionals and hobbyists who need reliable chamfered clearance holes for metric threads, the Dormer Pramet A412 M8 HSS Straight Shank Drill delivers precise starting geometry with an 118° pilot and a 90° chamfer. This setup guides the drill to the correct clearance diameter for M8-threaded holes, helping you achieve accurate fits and reduce post-drilling deburring.
Built for versatility, this drill uses premium high-speed steel and a steam oxide finish to minimize material sticking to the cutting edge, promoting cleaner starts, better chip control, and longer edge life. Its exact pilot diameter and length ensure the right clearance drilling depth for standard threads, and the straight shank design makes it compatible with both CNC and conventional machines across a range of materials.
- Precise chamfered clearance geometry: 118-degree pilot with a 90-degree chamfer and a defined pilot diameter/length to consistently create the correct clearance diameter and depth for standard metric threads.

- Premium HSS with broad material compatibility: Suitable for drilling steel, aluminium, and stainless steel, and compatible with both CNC and conventional machines for flexible, reliable use.
