Portable keyway milling machine (available in 2 models) needs only 38 mm space on the end of shaft to cut new keyway, without dismantling the shaft from assembly. Cutting time for 25 mm wide, 12.5 mm deep & 150 mm long keyway is less than 15 minutes. Mc makes a keyway on a ball mill shaft, while the shaft is in assembly. Sealed lubrication permits operation at any position of the machine. With the "v" type-mounting base, the keyway cutter will self-center onto an existing shaft, once the milling machine tool is clamped in place. The keyway cutter is capable of cutting keyways.
