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.
