With this three-piece set of impact-ready step drill bits, you'll get the job done more efficiently with less reactionary torque -- in less time. They're optimized for your impact driver with its 1/4-inch hex shank, but they also deliver strong performance every time in rotary drill drivers.
The advanced double spiral flute design outperforms straight flute design and extends the life of the bit. The split point tip increases speed, and they also include laser-engraved measurements to increase step visibility. This package includes a 4 to 12 mm bit, a 6 to 20 mm bit, and a 4 to 30mm bit.
Among the wide variety of applications these bits can be used for, they're ideal for drilling into cans, panels, and junction boxes for electricians; enlarging holes in ducts for HVAC applications; and enlarging door hardware for carpenters.
