Focus on the KM3000
The KM3000 is made for cutting keyways or milling flats on shaft diameters from 0.75 to 10.5 inches (20 to 270 mm), and requires only 1.5 inches (38 mm) of shaft for a secure mount. With accessories, it can cut a full depth, 0.5-inch (12 mm) wide, 6-inch (150 mm) keyway in 5 minutes. Triple gear reduction provides plenty of torque from its electric, pneumatic, or hydraulic motor.
