Keyway milling is the cutting of a keyway along the axis of the cylindrical surface of shafts or other items. Our portable Keyway milling machines allow us to cut new or re-cut worn keyways in shafts as little as 3/4 inch (19mm) up to 24 inches (610mm) outside diameter. We also have available a side-shift Key Milling machine which is for extra wide keyway milling which can be either bench mounted or mounted to shafts 8 inches to 24 inches in diameter. All BLJ In-situ Solutions machines are supplied with tooling and equipment required to setup and operate.
