Flute Geometry

THUNDERWEB flute form ejects hot chips rapidly. Dissepates heat better increasing lifetime.

Open flute form reduces drill drawback when drilling deeper holes.

Sharpened edges reduce binding for faster cleaner cuts.

Flatter twist angle creates smaller chippings, ideal for drilling harder steels ie: stainless steel.

135° Split Point

Precision starting, drill won't walk.

Penetrates quickly.

Good for drilling on curved surfaces.

Requires less effort / feed pressure.

Excellent for very hard materials.
