1/2" x 4-3/4" CNC 4-Facet 118° Drill Point Bit, 1/2" Shank

Amana Tool's 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". Our 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. 3" of cutting height.
