61/64 inch Reduced Shank Drill Bit

The Cle-Line C17059 is a high-speed steel drill bit sized at 61/64 inch with a 118 degree point angle. It features a reduced 1/2 inch shank to fit standard drill chucks. The black and gold finish identifies the machining-grade material. This accessory suits maintenance and fabrication tasks requiring a large-diameter hole.

118 Degree Point for Steady Cutting

The 118 degree point angle centres the bit quickly and maintains a consistent cutting action through the workpiece. High-speed steel construction resists heat buildup during extended drilling cycles. The reduced shank transmits torque without slipping in a three-jaw chuck. This geometry supports repeatable holes in steel and cast iron.

Black and Gold Finish Reduces Friction

The surface treatment lowers friction between the flutes and the material being drilled. Lower friction means less heat generated at the cutting edges during normal operation. Reduced heat helps preserve the temper of the high-speed steel body. The bit runs cooler and quieter than uncoated equivalents under the same feed pressure.

Questions about this item

How much heat does the 118-degree point generate during extended drilling?

The 118-degree point angle on this high-speed steel bit is designed for general-purpose cutting, which typically produces moderate heat that standard cutting fluid can manage during long sessions.

What shank size must my drill chuck accept for the 1/2 reduced shank to fit?

Your drill chuck must accommodate a 1/2 inch shank diameter, as the reduced shank on this 61/64 inch bit steps down to that size for compatibility with standard 1/2 inch capacity chucks.

Will the black-and-gold finish on this bit wear differently when used with older cast-iron workpieces?

The black-and-gold surface treatment on the high-speed steel provides consistent wear resistance across ferrous materials, so performance on older cast iron matches that on newer steel stock.
