Where this product is used

Step drills drill and deburr in one operation — each step is a different diameter, making them ideal for sheet metal work where multiple hole sizes are needed.

• Stepped hole sizing in sheet metal, aluminium, and thin steel without a pilot hole
• Electrical trade knockout drilling and hole enlargement in enclosures and panels
• Sheet metal fabrication where multiple hole sizes are needed from one tool

Key specifications

Selecting the right option

Step drills are designed for thin material — sheet metal, conduit, aluminium extrusion. The step diameter range must cover the hole sizes needed. Cobalt step drills outlast standard HSS on stainless steel and hard alloys. Use a centre punch to prevent the tip from wandering on smooth surfaces.
