Value Collection SC05879853 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879853 is a Type Z rotary tool holder bushing designed for use in drill press and milling machine tooling setups. It provides a precise, rigid interface between the tool holder and the machine spindle or tooling block. The bushing features a 0.5 inch (0.5000 inch) inside diameter and a 1.75 inch (1.7500 inch) outside diameter, with a 3.5 inch length under the head and a 0.75 inch head thickness. A 3.125 inch slot runs along the body to facilitate secure seating and tool alignment. Licensed machinists and toolroom technicians are the primary installers of this component.

This bushing is suited for precision machining environments where accurate tool positioning is required. Typical applications include production tooling fixtures, rotary tool holder assemblies, and drill press setups in both job shop and manufacturing environments. The Type Z classification indicates a standardized geometry used across common tooling systems, making it a straightforward drop-in component for compatible holders. It is appropriate for both light and moderate-duty machining operations.

Key Features

• Type Z bushing geometry for standardized tooling compatibility
• 0.5 inch inside diameter for precise tool or shank fit
• 1.75 inch outside diameter provides stable seating in the holder bore
• 3.5 inch length under head accommodates deep fixture or plate installations
• 3.125 inch slot length supports secure locking and alignment
• 0.75 inch head thickness resists axial pullout under load

Compatibility

Designed as an OEM-style replacement or standard-fit component for rotary tool holder assemblies that accept Type Z bushings with a 1.75 inch outside diameter and 0.5 inch inside diameter.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing any tooling bushing. Ensure the receiving bore is clean and free of chips or burrs before pressing or sliding the bushing into place. Do not exceed the tooling system manufacturer's rated load or speed specifications for the holder assembly.
