Cobalt Parabolic Taper Lengh Drill

Cobalt Taper Length Drills with Parabolic Flutes - Pittsburg Alleghany, Quality Import

Taper Length Drills with Parabolic Flutes are recommended where greater chip clearing capability is needed. 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. They are used when a drill longer than a Jobbers Length is required. Shanks are the same diameter as the drill diameter.
