4mm Cobalt Multi-Rake Drill Bit. Evolutionary Drilling

MULTI-RAKE DRILL BITS - a stronger, smarter, sharper solution

A new new age in drill bit technology has arrived. 5 years of research and development has delivered a drill bit that will forever change the drilling industry. Using the highest quality straight shank drill bits, a machining process is applied resulting in a quad-rake self-centring drill tip that is guareenteed to out perform and outlast any standard drill bit.

Available in both colbalt and high speed steel (HSS) compounds, and 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
• American Standard: ASMEB94.11M-1993
• German Standard: DIN 1414-1, 2-1998
• Chinese Standard: GB/T179484-2000

SUPERIOR PERFORMANCE

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
• the inner rake
