Step Drill Bits Set (6pcs)

Functionality: Step drill bits are designed to drill holes of various diameters in thin materials, particularly sheet metal, using a single bit. They can also be used for chamfering and deburring. Design: These bits have a conical shape with multiple steps, each corresponding to a different diameter, eliminating the need to frequently change bits for different hole sizes. Applications: They are ideal for use in materials like plastic, aluminum, and iron, and are commonly used in auto body repair or sound system installations for creating precise holes. Features: Many step drill bits feature a split-point tip for easy starting without pre-punching, a CNC ground spiral flute for efficient chip removal and reduced vibration, and a 3-flat shank to prevent slipping in the drill chuck.
