AT ProBits® Multi-Step Drills
AT ProBits multi-step drills—often called step drill bits—are designed to drill and enlarge holes in thin materials using a single tool (application dependent). Step drills are commonly chosen for sheet metal, fabrication, and electrical work because they can create multiple hole diameters, help produce cleaner holes, and reduce the need to switch between multiple drill sizes. Many users also rely on step drills for controlled hole enlargement and light deburring after drilling.
