Step drills

Step drills are specialized cutting tools designed to drill and enlarge holes in incremental diameters in a single pass. They are widely used on thin sheet metal and tubing, where a clean, burr-minimized hole and controlled cutting action are required. Compared with standard twist drills, step drills help reduce grabbing and improve consistency when opening holes to the exact size.

In this collection you’ll find step drills with different diameter ranges and step pitches, suitable for steel, stainless steel, aluminum, and plastics. Options include wear-resistant surface finishes, cutting geometries for smooth chip evacuation, and stable self-centering starts, as well as versions intended for handheld drills or drill presses. Reliable choices from Hepyc are available for repeatable shop-floor performance.

Step drills are commonly selected by maintenance technicians, electricians, panel builders, and metal fabrication professionals for enclosures, junction boxes, HVAC installations, automation projects, and general industrial manufacturing—applications where hole accuracy, surface finish, and process efficiency matter.
