Designed with a 1/4″ hex shank for quick changes in compatible drivers and drills, each bit uses spiral flutes to help clear chips as you work. Two depth stop collars and a hex key are included to help you set a consistent drilling depth and reduce the chance of over-drilling across repeated holes.
This set is intended for use on wood, plywood, MDF, particleboard, plastic, and drywall. When you’re done, everything stores in the included lightweight, labeled case for fast identification on the next project.
