4 Facet 118° Solid Carbide Fractional Drills
Router collet reducer RB-102 (1/4 to 1/8) available for 1/8 shank bits.
118° • 2-Flute • Jobber Length
4 facet jobber length fractional drills consist of 2 cutting edges with 2 facets per cutting edge. The facets consist of the lip relief and the lip clearance angle.
Multi-faceted drill geometries translate into improved centering accuracy, thereby producing rounder, precise holes less likely for "bell-mouthing". Amana Tool's premium-grade carbide substrate insures increased tool life by a minimum factor of 10X's over HSS coated bits, all while often eliminating the need for a prior center punch or spotting procedure. Also good for drill press.
