Step Drill bits are designed to incrementally increase in size along the length of the cutting tool, with each step of the drill enlarging the hole as it cuts through your workpiece. This progressively larger drill allows you to perform range of one-step drilling operations without time-consuming and productivity-halting tooling changes. Additionally, the step drill is designed to accomplish your drilling and counterboring, countersinking, or chamfering tasks all at once. Order your custom cutting tool today!
