Global Cnc Industries 8603B 1.000 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8603B 1.000 is a Type B rotary tool holder bushing designed for use in drill presses, milling machines, and CNC machining centers. It provides a precise bore interface between the tool holder and the machine spindle or tooling block, ensuring accurate tool positioning and reduced runout. Key dimensions are a 1 inch inside diameter, 1.5 inch outside diameter, and a 2.5 inch length under head. The head thickness of 0.265 inches provides a positive stop at the mounting surface. This bushing is typically installed by machinists and CNC setup technicians in production and job-shop environments.

This Type B bushing is suited for applications requiring a standardized drill or tool holder interface in both manual and CNC machine tool setups. It fits into tooling plates, jig plates, and fixture blocks where a 1 inch bore is required. The 2.5 inch length under head accommodates moderate plate or block thicknesses, making it appropriate for general-purpose fixture and tooling work in light to medium machining operations.

Key Features

• Type B configuration with a 0.265 inch head thickness for a positive seating stop
• 1 inch inside diameter for standard tool shank or liner bushing fitment
• 1.5 inch outside diameter for installation into standard Type B bushing receiver bores
• 2.5 inch length under head accommodates a range of fixture plate thicknesses
• Compact, single-piece construction for reliable, repeatable tool location

Compatibility

Designed as a standard Type B rotary tool holder bushing for use in jig and fixture plates, tooling blocks, and drill jig applications requiring a 1 inch ID and 1.5 inch OD bushing interface.

Installation Notes

Installation is typically performed by a machinist or CNC tooling technician. Ensure the machine is powered down and all stored energy is released before servicing tooling or fixture components. The bushing bore and mating receiver should be clean and free of chips or burrs before pressing or seating the bushing. Verify dimensional fit against the fixture plate or tooling block specifications before final installation.
