The Dormer Pramet A266 centre drill is a durable HSS-E tool designed to create precise centre holes on shafts, essential for secure holding and accurate alignment. With a TiAlN coating and a double-ended design, it’s built for reliability in both production and workshop settings.

• Diameter x length: 5.00 mm diameter, 12.50 mm overall length
• Coating: Titanium Aluminium Nitride (TiAlN) coating for longer wear life and improved heat resistance
• Material: Premium HSS-E (high-speed steel, extra tough) for versatile drilling across metals
• Geometry: 118° pilot with a 60° centre cone, DIN 333A compliant
• Double-ended design: Two drilling ends provide extended life and greater value per tool
• Applications: Suitable for CNC and conventional machines, effective on steel, aluminium, and stainless steel

This centre drill delivers true centre holes that ensure secure workholding and accurate alignment, reducing runout and enabling precise subsequent drilling or milling. The TiAlN coating minimizes wear when working with harder materials, while the double-ended configuration enhances productivity by offering two usable ends. Ideal for shaft-centre drilling in both controlled production environments and everyday workshop tasks.
