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.
