Value Collection SC05879127 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879127 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and precision machining setups. With a 1 inch inside diameter, 1.5 inch outside diameter, and a length under head of 2.5 inches, this bushing guides cutting tools accurately and reduces wear on the workpiece fixture. The 3/16 inch (0.265 inch) head thickness seats flush against the jig plate surface. This style of press-fit or slip-fit liner bushing is a standard component in toolroom, production machining, and metalworking environments, typically installed by machinists or tool-and-die technicians.

Type J renewable bushing liners are used in drill jig applications where repeatable hole location is critical. This bushing fits into a standard Type J liner and accommodates a 1 inch drill, reamer, or boring bar. Common applications include production drilling fixtures, assembly jigs, and custom workholding setups in machine shops handling ferrous and non-ferrous materials. The distance between hole centers is 1-1/8 inches, which is relevant when locating multiple bushings on a common fixture plate.

Installation Notes

Installation of drill jig bushings is typically performed by a machinist or toolmaker. Ensure the mating liner bore is clean and free of burrs before pressing or sliding the bushing into place. Do not use excessive force that could distort the bushing bore or damage the fixture plate. Follow applicable shop safety procedures and lock out any machine spindles before servicing or replacing bushings in an active fixture.
