Introducing the Dormer Pramet A225 centre drill (BS 328), a compact, double-ended HSS tool designed to start precise centre holes in shafts. Ideal for engineers, technicians, machinists, and hobbyists, it helps ensure repeatable alignment and secure holding during machining.

This centre drill combines a 120° pilot with a 60° center cone for reliable centering, and a bright finish to minimize sticking.

• Double-ended design: Two drilling ends give you more holes per tool and reduce downtime by letting you flip to a fresh edge—boosting productivity and saving cost per hole.
• 120° pilot and 60° center cone: Delivers precise centre holes in shafts for secure holding and accurate alignment in fixtures, improving repeatability and reducing setup errors.
• Bright finish and premium HSS: Bright finish minimizes material sticking to the cutting edge, while premium high-speed steel enables drilling across a wide range of materials including steel, aluminium, and stainless steel, and is suitable for both CNC and conventional machines.

This centre drill is built for dependable performance in both CNC and traditional machining environments. Its robust design supports consistent centering, faster setups, and reliable results across a wide range of materials, helping you improve workflow and achieve better finish quality with fewer rework steps.
