Amana tool SCFD-106 Solid Sub Micrograin Carbide 4 Facet Point 118 Deg x 7/32 Dia x 1-3/4 Cut Length x 7/32 Shank x 3 Inch Long Jobber Length Fractional Dril

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.
