<br />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.<br /><br />Parabolic web cross section: Large web thickness. Strength built in.<br /><br />Flute geometry - THUNDERWEB flute form ejects hot chips rapidly. Dissipates heat better increasing life time.<br /><br />135° Split point - Precision starting, drill bit won't walk on material surface.<br /><br />Polished finish reduces friction and extends drill bit life.<br /><br />Impact resistant ABS case with added rubber corner protection.<br /><br />Accepts higher feed pressure and torque equalling less breakages.">
