Global Cnc Industries 8612C .875 Tool Holder Bushing Type C

Product Description

The GLOBAL CNC INDUSTRIES 8612C .875 is a Type C rotary tool holder bushing designed for use in CNC machining centers, drill presses, and manual milling setups where tooling must be precisely located and retained within a tool holder or turret. With an inside diameter of 0.875 inches and an outside diameter of 1.25 inches, this bushing provides a close-tolerance fit for shanked tooling. The 3.25-inch length under head and 2.875-inch slot length accommodate standard Type C bushing applications. Machinists and toolroom technicians install this component during tooling setup and changeover operations.

This bushing is suited for production and job-shop environments where repeatable tool positioning is required. It fits into Type C bushing seats found in a range of rotating tool holders and fixture plates. The slot feature allows for locking pin engagement to prevent rotation under cutting loads. Typical applications include drilling, reaming, and boring operations on both CNC and manual equipment. Toolroom technicians and CNC setup personnel are the primary installers of this component.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine before seating or removing any tooling bushing. Verify that the bushing seat in the holder or fixture plate is clean and free of chips before pressing or hand-fitting the bushing into position. Do not force the bushing with impact tools, as this may damage the seating bore or bushing head.
