403H42 Drill Bit Blanks

Bulk orders will be discounted, please contact us.

These cobalt drill bit blanks come in standard sizes expressed in fractional inches. Fractional inch is the most common trade size used for drill bits. Cobalt steel drill bit blanks provide more wear resistance at higher speeds than high-speed steel drill bit blanks and are suitable for drilling into hard materials. Sometimes known as drill rods, these metal rods can be machined to make custom drill bits with precise dimensions to suit a particular application. They can also be used to check the size of a drilled hole or to create gauges, drifts, punches, rollers, locating pins, spindles, and knockout pins.
