Value Collection SC84949429 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949429 is a Type J rotary tool holder bushing designed for use in drill presses, milling machines, and CNC tooling setups where precise tool alignment and secure holder retention are required. With a 0.5-inch inside diameter, a 2.5-inch outside diameter, and a 4-inch length under the head, this bushing provides stable guidance for rotating tooling in production and maintenance environments. The head measures 0.333 inches thick, keeping the bushing seated flush in the fixture plate. At 2.31 pounds, this is a solid, production-grade component suited for machine shops and industrial maintenance operations.

Type J tool holder bushings are used in jig plates, drill fixtures, and tooling blocks where a flanged retention style is required. The 1.75-inch distance between hole centers and 0.875-inch D-In dimension match standard tooling plate layouts found in general machining and metalworking setups. This bushing is appropriate for both job shop and production line use by machinists, toolmakers, and maintenance technicians working with rotating tool holders.

Installation Notes

Installation is typically performed by a machinist or toolmaker. Power down and de-energize the machine before removing or installing any tool holder bushing. Verify the fixture plate bore and depth match the bushing OD and length under head before pressing the bushing into position. Follow applicable OSHA machine guarding and lockout/tagout procedures during service.
