Value Collection SC84949528 Tool Holder Bushing Type J

Product Description

The VALUE COLLECTION SC84949528 is a Type J rotary tool holder bushing designed for use in drill press and milling machine tooling setups. This bushing features a 1 inch inside diameter, a 3 inch outside diameter, and a 4.5 inch length under the head, making it suitable for applications that require rigid, concentric tool support. The head thickness measures 0.365 inches, providing a stable shoulder for seating in the holder. Weighing 2.464 pounds, this is a substantial, solid bushing intended for professional machine shop environments. Licensed machinists and toolroom technicians are the primary installers of this component.

Type J tool holder bushings are commonly used in CNC machining centers, knee mills, and drill presses where a standardized bushing is needed to adapt tooling to a specific spindle or holder bore. The 2 inch distance between hole centers accommodates standard mounting configurations found in production and job-shop machining setups. This bushing is appropriate for both light-production and precision one-off machining work where concentricity and rigidity are critical to tool performance and workpiece accuracy.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before installing or removing any tool holder bushing, power down the machine and confirm the spindle has fully stopped. Ensure the bore and bushing mating surfaces are clean and free of chips or burrs before pressing or seating the bushing. Verify that the bushing is fully seated and the head is flush against the holder face before resuming machine operation.
