• THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the back of the drill bit. • Standard drill bits have a constant thickness throughout their length. • 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. • Accepts higher feed pressure and torque equalling less breakages.
