- 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.
- Polished finish reduces friction and extends drill bit life.
- 135° Split point - Precision starting, drill bit won't walk on material surface.
- Impact resistant ABS case with added rubber corner protection.
- Accepts higher feed pressure and torque equalling less breakages
