Benefits of Parabolic Flute Form
Heavy web construction increases rigidity under torsional load thus eliminating chatter at the cutting edges which cause edge breakdown and early failure. The Parabolic drill web is 50-90% thicker than the standard drill, depending on diameter.
Wider flute form, together with quicker spiral, promotes better chip removal while allowing easier coolant flow to the drill point.
