Standards Approved

Available in both colbalt and high speed steel (HSS) compounds, metric and imperial sizes, the Multi-Rake drill bit is manufactured and quality assured to the highest International standards.

• International Standard: ISO 108 991 996

• Chinese Standard: GB/T179484-2000

Technology

With 4 independant rake angles machined into the drill tip, multi-rake drill bits are designed to optimise and maximise drilling performance and longevity. The rake angles - inner, outer, centering and separation - combine to create superior drilling experience in every aspect.

• the centering rake is a self-centering feature that eliminates "slippage" at drilling start
• the outer rake provieds a cleaner surface finish on the hole wall
• the separation rake significantly reduces drilling temperatures, subsequently providing an easer drilling experience
