Dormer Pramet A266 2.50 mm x 6.30 mm HSS-E TIALN METRIC 60DEG CENTRE DRILL DIN 333A

Designed for precision centre drilling in shafts, the Dormer Pramet A266 centre drill delivers reliable centering and durable performance on both CNC and conventional machines. With an 118° pilot and a 60° cone, it starts cleanly and produces accurate, secure holes every time.

• Diameter × length: Ø 2.50 mm × 6.30 mm overall length
• Material: Premium HSS-E (High Speed Steel – Enhanced) for broad material compatibility and long life
• Coating: Titanium Aluminium Nitride (TiAlN) coating to extend service life and improve performance on harder materials
• Angles: 118° pilot with a 60° centre cone for precise centering and clean entry
• Double-ended: Two drilling ends increase productivity and reduce tool-change frequency
• DIN standard: DIN 333A designation ensures compatibility with common centre drilling setups
• Applications: Suitable for drilling centres in steel, aluminium, and stainless steel, usable in CNC and conventional machines

This centre drill combines durable HSS-E with a TiAlN coating to deliver longer life and steadier performance, especially when working harder or tougher materials. The double-ended design minimizes downtime by giving you two usable ends, while the 118°/60° geometry provides reliable centering and clean hole starts. Ideal for technicians and engineers who need consistent, repeatable centre holes for secure workholding across mixed-material projects.
