Metal Long Step Drill Bits

Introduction to Step Drill Bits

Step drill bits, also known as conical drill bits or stair-step drill bits, are specialized tools designed for drilling holes of varying diameters in a single operation. These bits are particularly useful in metalworking and fabrication due to their ability to create multiple hole sizes without the need for changing tools. The design of step drill bits features a conical shape with a series of steps or flutes that allow for incremental drilling.
