The Greenlee GSB09 GSB Series Step Bit is a professional-grade drilling tool designed to create multiple hole sizes in a single workpiece without the need for frequent bit changes. Its patented split-step design and progressive cutting edges solve common jobsite issues like bit stalling and uneven chip loading, ensuring smooth and efficient performance.
- Durable split-point tip enables fast and accurate material penetration while preventing bit walking on smooth surfaces.
- Improved double flute design provides superior chip evacuation and faster cutting speeds, which extends the overall life of the tool.
- Three-flat shank prevents the bit from slipping in 1/2-inch drill chucks, providing a secure grip for high-torque applications.
This step bit is ideal for electrical contractors, HVAC technicians, and maintenance professionals who need to drill clean, precise holes in mild steel, copper, brass, aluminum, and various plastics or laminates.
- Hole Sizes: 1/2 in, 7/8 in, 1-1/8 in
- Maximum Material Thickness: 10 gauge
- Number of Steps: 3
