Dormer Pramet A100 17.50 mm HSS ST STRAIGHT SHANK JOBBER DRILL DIN 338

The Dormer Pramet A100 17.50 mm HSS Straight Shank Jobber Drill (DIN 338) is a versatile metalworking drill designed for use in workshops, on machines, and in portable handheld setups. This 17.50 mm diameter drill is built to perform across a range of materials, making it a reliable choice for engineers, technicians, tradespeople, and hobbyists alike.

The drill features an 118-degree conventional point that starts holes cleanly and is easy to re-grind, a steam-oxide finish to minimize gumming at the cutting edge, and a patented silver ring that proves genuine Dormer quality and clearly marks the drill diameter, ensuring you have the right tool for the job.

• Sharp 118° point for reliable starts: The 118° point creates a strong center, reduces wandering, and is easy to re-grind when needed, helping you start holes accurately and prolong tool life.
• Steam-oxide finish for clean cutting: The steam-oxide coating reduces material sticking to the edge, improves chip flow, and supports smoother cuts across steel, aluminium, and stainless steel.
• Patented Silver Ring with premium HSS for versatile performance: The Silver Ring confirms genuine Dormer quality and diameter at a glance, while the high-speed steel core delivers reliable drilling across a range of metals in both handheld and machine applications.

When you choose this drill, you gain consistent hole quality, faster setup times, and fewer tool changes in mixed-material projects. The DIN 338 standard and straight-shank design ensure compatibility with a wide range of chucks and holders, while the durable HSS core stands up to steel, aluminium, and stainless steel drilling. In busy workshops or on the job site, you can trust predictable performance, easier re-grinding, and clear diameter verification to keep production on track.
