Global Cnc Industries 8601J .375 Type J Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8601J .375 is a Type J rotary tool holder bushing designed for use in drill presses, CNC machines, and other precision tooling setups. It features a 3/8 inch (0.3750 inch) inside diameter and a 3/4 inch (0.7500 inch) outside diameter, with a 1.5 inch length under the head. The head thickness measures 0.19 inch. This bushing supports accurate tool positioning and reduces runout in rotating tool applications. It is installed by machinists and CNC technicians as a precision fit component in tool holder assemblies. The compact, single-piece design suits high-repetition production environments where consistent bore alignment is required.

This Type J bushing is suited for use in rotary tool holder blocks and jig plates where a press-fit or slip-fit bushing is required to guide drill bits, reamers, or other rotating cutting tools. The 13/16 inch distance between hole centers and 0.333 inch D-In dimension make it compatible with standard Type J bushing configurations used in metalworking and light manufacturing operations. It is appropriate for both manual machine setups and automated CNC tooling environments requiring repeatable part location.

Key Features

• Type J rotary tool holder bushing for standard jig and fixture applications
• Inside diameter: 3/8 inch (0.3750 inch) for precise tool shank fitment
• Outside diameter: 3/4 inch (0.7500 inch) for standard tool holder bore compatibility
• Length under head: 1.5 inches for adequate tool guidance depth
• Head thickness: 0.19 inch for low-profile seating in holder assemblies
• Single-piece construction for straightforward installation and replacement

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type J rotary tool holder bushing applications in drill press jigs, fixture plates, and CNC tooling blocks.

Installation Notes

Installation is typically performed by a machinist or CNC technician. Power down and lock out the machine before removing or installing any tooling bushing. Ensure the mating bore in the tool holder block is clean and within tolerance before pressing or sliding the bushing into place. Do not force the bushing with impact tools if a slip fit is specified, as this may damage the bore or affect alignment.
