Step Drill Bits Described

This news reports on the compatibility of these drills with all jobsite drills.

Double-fluted step drill bits feature ¼ in. hex shank, as well as aggressive split point tip that prevents skidding across surface and eliminates need to make pilot hole or punch. Each 1/16 in. multi-diameter step is radius-blended to smoothly transition from one step to next.

If you planning to buy drill bits, consider and try these products and decide whether they are useful for your long-term drilling job.
