Global Cnc Industries 8603B .500 Type B Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8603B .500 is a Type B rotary tool holder bushing designed for use in precision tooling setups on CNC machines and manual lathes. It features a 0.500 inch inside diameter, a 1.500 inch outside diameter, and a length under head of 2.500 inches. The head thickness measures 0.265 inches. This bushing guides and supports rotating tools or workpieces within a tool holder or turret, helping maintain alignment and reducing runout during machining operations. Installation is typically performed by machinists and CNC setup technicians as part of tooling configuration or replacement.

This bushing is suited for shop-floor use in both production and job-shop environments. It fits applications where a Type B bushing profile is required, such as gang tooling setups, turret lathes, and rotary tool stations. The 0.500 inch bore accommodates standard half-inch shanks or workpieces, making it a common size in general metalworking applications. The part ships in a quantity of one and has a minimum order quantity of one unit.

Installation Notes

Installation is typically performed by a qualified machinist or CNC technician. Power down and lock out the machine at the control and main disconnect before removing or installing any tooling components. Ensure the receiving bore and bushing exterior are clean and free of chips or burrs before pressing or sliding the bushing into position. Verify alignment and runout with a dial indicator after installation before returning the machine to operation.
