Forstner Bits

Drawing upon years of experience in making the highest quality forstner bits available, the Stern bit has been redesigned to include a tooth-like pattern on the outside rim of the tool. These teeth assist in the cutting action, and yet still offer the same advantages of the traditional forstner bit. These bits are guided by their circular rim instead of their center, and consequently will bore any arc of a circle and can be guided in any direction regardless of grain or knots. Bores a flat bottom hole. Set of five sizes indicated by *, set of eight sizes by +.
