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.\u003c\/p\u003e\u003cp\u003eThis 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.
