Value Collection SC05879721 Type Z Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879721 is a Type Z rotary tool holder bushing designed for use in drill press and milling machine tooling setups. It features a 3/8 inch inside diameter and a 1-1/4 inch outside diameter, with a 3 inch length under the head and a 5/8 inch head thickness. The 2-5/8 inch slot length allows for proper engagement and retention within compatible tool holders. This bushing is typically installed by machinists and tool room technicians to locate and support cutting tools or workholding components with precision and repeatability.

Type Z bushings are a standardized format used across a wide range of machining operations, including drilling, reaming, and boring. They are commonly used in production and maintenance environments where consistent tool alignment is required. The fixed-style design suits applications where the bushing remains stationary in the jig or fixture plate. This part ships as a single unit and is suited for both replacement and new fixture builds.

Key Features

• Type Z bushing configuration for use in standard jig and fixture applications
• 3/8 inch inside diameter accommodates common drill and reamer shank sizes
• 1-1/4 inch outside diameter for secure press-fit or slip-fit installation in tool plates
• 3 inch length under head provides extended tool guidance and support
• 2-5/8 inch slot length for positive retention and tool alignment
• 5/8 inch head thickness adds stability at the seating surface

Compatibility

Designed as a standard Type Z rotary tool holder bushing for use in drill jigs, fixture plates, and tooling setups requiring a 3/8 inch inside diameter and 1-1/4 inch outside diameter bushing.

Installation Notes

Installation is typically performed by a machinist or tool and die technician. The bushing should be pressed or driven into the fixture plate bore using an appropriate arbor press to avoid damage to the head or bore surface. Ensure the mating bore in the fixture plate is machined to the correct tolerance for the intended fit class before installation. Verify tool clearance and alignment before resuming machine operation.
