The Dormer Pramet A225 centre drill is a precision HSS tool designed to start holes cleanly and accurately, making it ideal for creating centre holes in shafts that need secure holding during turning or milling. With a 120° pilot and a 60° cone, it guides the drill smoothly into the workpiece for reliable starting accuracy. This BS 60° centre drill is suitable for both CNC and conventional machines, helping you achieve consistent alignment in production tasks.
Built from premium high-speed steel, this centre drill can be used on a wide range of materials, including steel, aluminium and stainless steel. The bright finish reduces workpiece material from sticking to the cutting edge and promotes easier chip clearance, while the double-ended design provides two drilling ends for greater productivity and economy.
- Double-Ended Design: Two drilling ends extend tool life and reduce replacement frequency, boosting productivity and lowering operating costs.
- Precise Centering: 120° pilot and 60° cone deliver accurate centre holes in shafts for secure holding and reliable alignment during subsequent machining.
- Bright Finish for Smooth Cutting: Bright finish minimizes material sticking to the edge and aids chip flow, helping you finish holes cleanly and consistently.
With the A225 centre drill, you gain a dependable starting point for accurate, repeatable centre holes across a variety of materials, compatible with both CNC and manual equipment. The combination of premium HSS construction, dual ends, and a precise center geometry supports faster setups, fewer interruptions, and consistently aligned parts—delivering improved workflow and higher-quality results in everyday workshops and production environments.
