Global Cnc Industries 8607B 1.000 Rotary Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8607B 1.000 is a Type B rotary tool holder bushing designed for use in machining and CNC tooling setups. It features a 1-inch inside diameter, a 3-inch outside diameter, and a 4.5-inch length under the head, with a head thickness of 0.365 inches. This bushing locates and supports rotating tools or workholding components within tool holder assemblies, maintaining precise alignment during machining operations. Installation and replacement are typically performed by machinists or tooling technicians working on CNC lathes, milling machines, or similar rotary equipment.

This Type B bushing is suited for industrial machining environments where accurate tool or spindle support is required. It fits applications that call for a 1-inch bore and a 3-inch outer diameter seating surface, making it appropriate for a range of standard rotary tool holder configurations. At 8.53 pounds, the bushing is built for robust service in production or job-shop settings where repeatability and rigidity are critical to part quality.

Key Features

• Type B bushing configuration for compatibility with standard rotary tool holder designs
• 1-inch inside diameter (1.0000 inches) for precise bore fit
• 3-inch outside diameter (3.0000 inches) for secure seating in the holder body
• 4.5-inch length under head for adequate tool support depth
• 0.365-inch head thickness provides a positive stop and load-bearing shoulder
• Weighs 8.53 pounds, indicating solid, heavy-duty construction

Compatibility

Designed as a direct-fit replacement or upgrade bushing for rotary tool holder assemblies requiring a Type B bushing with a 1-inch inside diameter and 3-inch outside diameter.

Installation Notes

Installation is typically performed by a qualified machinist or tooling technician. Before removing or installing the bushing, ensure the machine spindle is fully stopped, locked out, and all energy sources are isolated per OSHA lockout/tagout procedures. Press or seat the bushing carefully to avoid damage to the bore or seating surface, and verify concentricity after installation before resuming machining operations.
