Step Drills

One tool, many diameters: step drills enlarge the hole in defined increments and replace an entire set of twist drills, especially in thin sheet metal, where a standard drill tends to grab and tear out. The edge stays clean and deburring happens as you drill on into the next step.

• Several diameters with one tool, no changeover
• Clean, round opening in thin sheet metal without grabbing
• Deburrs the hole as it passes into the next step
• Straight-fluted for smooth running and even feed
• Spiral-fluted for a soft cut and better chip removal
