The Greenlee 1-1/8" Multi-Hole Step Bit (#9) Metal Cutter delivers professional-grade performance for cutting mild steel, aluminum, brass, copper, wood, fiberglass, plastics and laminates. Featuring a patented split-step design and durable split-point tip, this 4-stage step bit provides fast, accurate material penetration with superior chip evacuation for extended tool life and optimal cutting performance.

Professional Features & Benefits

• 1-1/8" Maximum Capacity: Handles drilling tasks from 3/16" to 1-1/8" diameter in a single tool, reducing bit changes and improving workflow efficiency.
• 4-Stage Progressive Design: Multiple drill stages provide versatile hole sizing options while the progressive cutting edges maximize torque efficiency and minimize motor stalling.
• 10 Gauge Sheet Metal Rating: Cuts through sheet metal up to 10 gauge (3.5 mm) thickness, making it suitable for electrical, HVAC, and general metalworking applications.
• Split-Point Tip Technology: Durable split-point tip ensures fast, accurate material penetration and reduces walking on smooth surfaces for precise hole placement.
• Improved Double Flute Design: Superior chip evacuation design increases cutting speeds, extends tool life, and delivers more holes per battery charge in cordless applications.
• Three-Flat Shank: Compatible with all 1/2" drill chucks for secure grip and reduced slippage during high-torque operations.
• Laser Markings: Quick, easy product and size identification for efficient job site use and inventory management.

Installation & Operation

1. Mount the step bit securely in a 1/2" drill chuck using the three-flat shank design for optimal grip.
2. Mark the desired hole location and center punch if working on smooth metal surfaces.
3. Start drilling at low speed to establish the hole, then increase speed as the split-point tip engages the material.
4. Apply steady, moderate pressure and allow the progressive cutting edges to advance through each stage.
5. Clear chips regularly during operation to maintain optimal cutting performance and tool life.
6. Complete drilling to the desired diameter stage and withdraw the bit while the drill is still running.
