Value Collection SC05879663 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879663 is a Type Z rotary tool holder bushing designed to locate and support cutting tools within drill jigs and tooling fixtures. With an inside diameter of 0.25 inches, an outside diameter of 1.0000 inches, and a length under head of 2.75 inches, this bushing provides consistent tool alignment during drilling and reaming operations. The head thickness measures 0.50 inches, adding axial support at the fixture face. It weighs approximately 1.364 pounds. Machinists and toolroom technicians install this component in production jigs where repeatable hole location is critical to part quality.

Type Z rotary tool holder bushings are used in drill jig applications where the bushing rotates with the cutting tool rather than remaining stationary in the liner. This style is suited for operations involving reamers, counterbores, or other multi-edge tools that require the bushing to turn with the tool shank. The slot length of 2.375 inches accommodates the locking mechanism that secures the bushing during operation. Typical installations are found in production machining environments, tool rooms, and fixture-heavy job shops handling medium to high volume work.

Key Features

• Type Z rotary design rotates with the cutting tool to reduce wear on tool shanks
• Inside diameter of 0.2500 inches for precise 1/4 inch shank tool guidance
• Outside diameter of 1.0000 inches for standard liner fitment
• Length under head of 2.75 inches provides extended tool support through thick fixture plates
• Slot length of 2.375 inches accommodates the drive and locking mechanism
• Head thickness of 0.50 inches seats flush and stable against the fixture face

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 0.2500 inch inside diameter and 1.0000 inch outside diameter.

Installation Notes

Installation is performed by qualified machinists or toolmakers during fixture assembly or maintenance. Ensure the mating liner bore and fixture plate are clean and free of chips before pressing or sliding the bushing into position. The slot must align correctly with the drive key or locking pin on the associated tooling before securing the bushing. Always lock out or de-energize the machine before servicing or replacing jig bushings on an installed fixture.
