Walter SST+ ½” Prentice Drill Bit

This Walter SST+ ½” Prentice drill bit is a heavy-duty large-diameter bit built for portable drills, drill presses and magnetic base drills with a ½” chuck. The cobalt blend and extra-hard tip material extend the interval between re-sharpenings.

Suited for steel and non-ferrous metal drilling

It handles mild steel, non-ferrous metal and stainless steel. The 135-degree point geometry removes the need for a pilot hole and three flats on the shank stop slippage in the chuck. Buyers who need smaller diameters or bits for wood and masonry should choose a different style.

55/64 inch diameter with 3-1/8 inch flute

The cutting diameter is 55/64 inch, the flute length is 3-1/8 inch and the overall length is 6 inch. The 135-degree point angle and bronze SST treatment support faster drilling in the listed metals.
