The Dormer Pramet A210 centre drill is a precision metric radius-form tool designed to create accurate centre holes in shafts for secure workholding. With a 4.00 mm diameter and 10.00 mm length, it adheres to the DIN 333R standard to ensure reliable compatibility with standard setups.
Built for engineers, machinists, fabricators, and hobbyists alike, this HSS centre drill is versatile enough for both CNC and conventional machines. The radius-form geometry and 118-degree pilot deliver clean starts and controlled hole formation, while the bright finish helps prevent workpiece material from sticking to the cutting edge.
- Double-Ended Design: Two drilling ends provide increased productivity and economy by reducing tool changes and extending tool life per purchase.
- 118° Pilot with Concave Cone: Guides the drill precisely to the centre and creates a protected centre hole that helps secure the workpiece during machining.
- Premium HSS with Bright Finish: Robust high-speed steel handles a wide range of materials (steel, aluminium, stainless steel) and the bright finish minimizes sticking and improves chip flow on both CNC and conventional machines.
This centre drill helps you speed up setup, achieve consistent centre holes, and hold parts securely throughout machining. With a durable, two-ended design and broad material compatibility, it delivers dependable performance across production runs and prototyping alike—saving time and reducing downtime while delivering reliable results.
