Step Driils

Step drills are used for progressive drilling and enlargement of holes when fitted to standard drills, making them suitable for thin materials such as sheet metal, plastics and non ferrous metals. Commonly used in fabrication, electrical installation, HVAC and general trade environments, they allow multiple hole sizes to be created with a single tool, reducing bit changes and supporting controlled cutting.

Manufactured from high speed steel for durability and consistent cutting performance, step drills are available in popular size ranges including 4–12mm, 4–20mm, 4–30mm and 4–39mm. Designed for use with industry standard drills, they provide smooth finishes, reliable results and long service life when operated at appropriate speeds with suitable safety equipment.
