Global Cnc Industries 8605B 1.500 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8605B 1.500 is a Type B rotary tool holder bushing designed for use in machine tool setups where precise bore alignment and secure tool retention are required. With a 1.5-inch inside diameter and a 2-inch outside diameter, this bushing seats firmly in compatible tool holder blocks and drill jigs. The head thickness measures 0.295 inches, providing a low-profile seating surface. It is installed by machinists and CNC technicians as a hardened liner to guide rotating cutting tools, reduce bore wear, and maintain repeatable positioning in production environments.

This bushing is suited for use in rotary tool holders found in CNC machining centers, drill presses, and jig boring applications. The Type B designation indicates a specific head geometry that fits standardized bushing pockets commonly found in commercial and industrial tooling fixtures. At 3.5 inches of usable length under the head, it accommodates deeper tool penetration requirements common in production drilling and reaming operations. Machinists working with larger-diameter tooling will find this bushing sized for heavy-duty applications.

Key Features

• 1.5-inch inside diameter for compatibility with larger rotating tool shanks
• 2-inch outside diameter for firm seating in standard Type B bushing pockets
• 3.5-inch length under head suits deep-reach tooling applications
• 0.295-inch head thickness provides a low-profile, stable seating flange
• Type B head geometry conforms to industry-standard bushing configurations

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for rotary tool holder systems that accept Type B bushings with a 2-inch outside diameter and 1.5-inch inside diameter bore.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Ensure the machine spindle is fully powered down and locked out before removing or inserting tool holder bushings. The bushing should be pressed or seated by hand into the tool holder pocket without impact tools that could damage the bore or head seating surface. Verify bore cleanliness and check for wear in the receiving pocket before installation to maintain alignment tolerances.
