Description

Features:

• THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the back of the drill bit (1-13mm). Standard drill bits have a constant thickness throughout their length (13.5-20mm). Even at the narrowest point the THUNDERWEB core is thicker than that of a standard drill bit.


• Parabolic web cross section: Large web thickness. Strength built in.


• Flute geometry – THUNDERWEB flute form ejects hot chips rapidly. Dissipates heat better increasing life time.


• 135° Split point – Precision starting, drill bit won’t walk on material surface.


• Polished finish reduces friction and extends drill bit life.


• Impact resistant ABS case with added rubber corner protection.
