Value Collection SC84949536 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949536 is a Type J rotary tool holder bushing designed for use in drill press and milling machine tooling setups. It features a 1.25-inch inside diameter and a 3-inch outside diameter, with a 4.5-inch length under the head and a head thickness of 0.365 inches. The bushing provides a precision interface between the tool holder and the machine spindle or tooling block. It weighs 2.464 pounds, making it a solid, heavy-duty component suited for demanding machine tool environments. Licensed machinists and tool-room technicians are the typical installers for this type of component.

Type J bushings are used in production machining, tool-and-die, and maintenance environments where repeatable tool positioning is required. This bushing fits into a standard Type J tooling block or drill jig and accepts tooling with a 1.25-inch shank. The 3-inch OD provides a broad seating surface for stable mounting. It is well suited for horizontal and vertical machining setups that require a flanged bushing with a defined length under the head to position tooling at a specific depth.

Key Features

• Type J bushing configuration with flanged head for positive axial location
• Inside diameter of 1.25 inches for compatible tool shank fitment
• Outside diameter of 3 inches provides a wide, stable bearing surface
• 4.5-inch length under head accommodates deeper tooling blocks or jigs
• Head thickness of 0.365 inches for controlled seating depth
• Solid construction at 2.464 pounds for durability in production use

Compatibility

Designed as an OEM-style replacement or standard fitment for Type J rotary tool holder bushing applications requiring a 1.25-inch inside diameter and 3-inch outside diameter interface.

Installation Notes

Installation is performed by a qualified machinist or tool-room technician. Ensure the machine spindle and tooling block are fully de-energized and at a complete stop before inserting or removing the bushing. Verify bore cleanliness and check for burrs or scoring in the receiving bore before seating the bushing. Use appropriate pressing or driving tools if a press fit is required — do not strike the head directly with a steel hammer.
