Value Collection SC05879762 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879762 is a Type Z rotary tool holder bushing designed for use in machine tool setups where precise drill or tool alignment is required. With an inside diameter of 0.875 inches and an outside diameter of 1.25 inches, this bushing provides a secure, close-tolerance fit in standard jig plates and fixture bodies. The length under the head measures 3 inches, and the slot length is 2.625 inches, giving technicians adequate engagement depth for stable tooling support. The head thickness is 0.625 inches. Weighing 1.65 pounds, this is a solid, production-grade component suited for machine shops, toolrooms, and manufacturing fixture applications.

Type Z rotary bushings are used in drill jig fixtures where the bushing rotates with the cutting tool to reduce friction and wear during high-speed drilling operations. This bushing is appropriate for use in fixed or renewable liner applications found in production machining environments. It is typically installed and maintained by machinists, toolmakers, and fixture builders working in metal fabrication and precision manufacturing settings.

Key Features

• Type Z rotary bushing design allows the bushing to rotate with the drill, reducing wear on both the tool and the workpiece
• Inside diameter of 0.875 inches (7/8 inch) for standard tool shank compatibility
• Outside diameter of 1.25 inches (1-1/4 inch) for secure press or liner fit
• 3-inch length under head provides deep engagement for stable drill guidance
• 2.625-inch slot length accommodates standard locking configurations
• Head thickness of 0.625 inches (5/8 inch) for positive axial positioning

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig fixtures requiring a Type Z rotary tool holder bushing with a 7/8-inch inside diameter and 1-1/4-inch outside diameter.

Installation Notes

Installation is typically performed by a qualified machinist or toolmaker. Before installation or removal, ensure the machine is fully powered down and locked out per applicable safety procedures. Type Z rotary bushings are press-fit or installed into renewable liner bushings — verify bore tolerances in the jig plate before pressing to avoid damage to the bushing or fixture. Do not use impact tools during installation; use an arbor press and appropriate driver for controlled, straight seating.
