Global Cnc Industries 8602B .625 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8602B .625 is a Type B rotary tool holder bushing designed to locate and support cutting tools within tool holders and drill jigs in machining applications. With an inside diameter of 0.625 inches and an outside diameter of 1.0000 inches, this bushing provides precise tool guidance for consistent, repeatable results. The head thickness measures 0.265 inches, and the length under the head is 1.7500 inches. Machinist and toolroom technicians install this bushing into compatible tool holder bodies during setup on CNC mills, drill presses, and similar machine tools.

This bushing is suited for use in production and job-shop machining environments where accurate tool positioning is required. It fits standard Type B bushing seats and is appropriate for both light-duty and moderate-duty drilling and boring operations. The 0.625-inch bore accommodates commonly used drill shanks and tool shanks of that diameter. Installation is typically performed by a machinist or toolroom technician during machine setup or tooling changeover.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before inserting or removing bushings. Ensure the bushing seat in the tool holder is clean and free of burrs or debris before pressing the bushing into position. Do not force the bushing into an undersized or damaged seat, as this may affect concentricity and tool accuracy.
