The BB4500 lightweight-boring machine is ideal for line boring in limited-diameter applications, such as linkage pivot points, articulation joints, kingpins, hinge points on tilt-bed trailers and steering-axle sleeves on heavy-duty fork trucks. The tool can be powered pneumatically, hydraulically or electrically, and the various motors allow a quick two-bolt exchange. The BB4500's boring bar is 4.44 cm in diameter and available in length from 121.92 to 609.6 cm.
