Frequently Asked Questions

What is the HOLEMAKER TECHNOLOGY Step Drill Bit Set used for?

This 3-piece step drill bit set is used for drilling progressively larger holes in sheet metal, plastic, and wood. It is impact-rated for use with impact drivers, making it suitable for automotive, HVAC, electrical, and general fabrication work where quick, burr-free holes are needed.

What are the specifications of the HOLEMAKER TECHNOLOGY Step Drill Bit Set?

The set includes three TiN-coated high-speed steel bits with a 135° split point. Each bit drills from 5/16 in to 1-1/16 in in stepped increments. They are impact-rated (VersaDrive design) for use with impact drivers. The manufacturer part number is 506050-SET1.

How to select the right step drill bit set for impact drivers?

Choose a set that is explicitly impact-rated, like the HOLEMAKER TECHNOLOGY VersaDrive series, to withstand the torque and vibration of impact drivers. Ensure the size range covers your typical hole diameters (here 5/16 in to 1-1/16 in) and that the coating (TiN) suits your material for extended tool life.
