Value Collection SC84949437 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949437 is a Type J rotary tool holder bushing designed for use in drill presses, milling machines, and similar machine tool setups. It features a 0.625 inch inside diameter and a 2.5 inch outside diameter, with a 4 inch length under the head. The 0.3504 inch head thickness provides a positive seating surface that keeps the bushing securely positioned in the tool holder. Weighing 2.31 pounds, this bushing is built for shop floor use where dimensional accuracy and reliable tool retention are required. Machinists and toolroom technicians are the primary installers.

This Type J bushing is suited for production and maintenance machining environments where standardized tool holding is needed. It fits into drill jig and tool holder applications that call for a 2.5 inch outside diameter bushing with a 0.625 inch bore. The 1.75 inch distance between hole centers and 0.875 inch D-in dimension follow standard Type J geometry, making it a straightforward replacement or addition in setups that already use Type J tooling. Sold individually.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine before removing or seating any tool holder bushing. Ensure the mating bore in the tool holder is clean and free of chips or burrs before pressing the bushing into position. Verify dimensional compatibility with the existing holder before installation to avoid damage to the bore or bushing head.
