Dormer Pramet A210 1.25 mm x 3.15 mm HSS METRIC RADIUS FORM CENTRE DRILL DIN 333R

The Dormer Pramet A210 centre drill, 1.25 mm x 3.15 mm, metric radius form (DIN 333R), is engineered to create precise centre holes in shafts for secure workholding. Its 118° pilot with a concave cone promotes clean, accurate starting geometry, helping you achieve true alignment from the first cut.

This double-ended centre drill uses premium high-speed steel and a bright finish to reduce sticking and chip buildup, making it suitable for drilling a range of materials—from steel and aluminium to stainless steel. It’s designed for versatility and reliability on both CNC and conventional machines, delivering consistent results in demanding shop environments.

• 118° pilot with concave cone: Creates accurate centre holes in shafts, ensuring proper alignment and secure part holding for reliable machining.
• Bright finish for smooth cutting: Reduces material sticking to the edge and promotes easier chip flow, helping to maintain a clean cut and longer edge life.
• Double-ended design: Two drilling ends extend tool life and productivity, offering better economy and less downtime on busy shops.

With this A210 centre drill, you get predictable centre starts every time, minimizing misfeeds and misalignment during subsequent operations. The versatile HSS construction handles multiple materials, while the CNC-orientated geometry works well on modern machines as well as manual setups. The combination of durability, ease of use, and cost-effective two-ended design helps you improve throughput, reduce tool changes, and achieve precise, repeatable results across your projects.
