Value Collection SC05879978 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879978 is a Type Z rotary tool holder bushing designed for use in machine tool setups where precise tool positioning and support are required. With a 1.25-inch inside diameter and a 2-inch outside diameter, this bushing provides a secure, concentric fit for rotating tooling. The head thickness measures 0.75 inches, and the length under the head is 3.75 inches, making it suitable for applications requiring extended reach and rigid support. Machinists and toolroom technicians typically install this bushing in drill jigs, fixture plates, and rotary tool holder assemblies. The 3.125-inch slot length accommodates locking or locating features common in Type Z bushing configurations.

This bushing is suited for use in production machining environments, toolroom operations, and jig-and-fixture setups. It fits applications where a flanged, slotted bushing style is specified by the fixture or machine tool design. Type Z bushings are commonly used in renewable bushing liner systems where the bushing must be locked in place during drilling, reaming, or boring operations. Both job shop and high-volume production environments make use of this bushing style.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down all rotating equipment and secure the workpiece fixture before seating or removing the bushing. Use proper press-fit or hand-insertion procedures as specified by the fixture design — do not strike the bushing head directly with a steel hammer. Confirm that the slot orientation aligns with the locking pin or cam of the liner before seating fully.
