ONSITE+ Step Tip Step Drills

ONSITE+ step tip step drills (unibits) have a conical staircase profile that drills several discrete hole sizes in one bit. The self-centring step-tip eliminates the punch-mark, and they are impact-rated for cordless drivers.
Construction & Materials
Impact-rated conical unibit with a self-centring step-tip; marked diameters along the cone so you can read the size as you drill.
Drive & Use
Ideal for sheet metal where the operator needs four or five hole sizes without changing tools. Drill to the marked step for the size you want.
