The 29 Piece Cobalt Screw Machine Drill Bit Set 1/16"–1/2" x 64ths includes fractional drill sizes in 1/64 inch increments, providing precise size selection for accurate drilling applications. Manufactured from cobalt steel, these drill bits offer excellent heat resistance and durability when drilling stainless steel, alloy steels, and other hard metals.

Designed with a screw machine (stub length) profile, these drill bits are shorter than standard jobber drills, providing increased rigidity and reduced deflection during drilling. This design makes them ideal for CNC machines, drill presses, and screw machines, as well as precision drilling tasks where stability and accuracy are critical.
