Global Cnc Industries 8612C .625 Tool Holder Bushing Type C

Product Description

The GLOBAL CNC INDUSTRIES 8612C .625 is a Type C rotary tool holder bushing designed for use in CNC machining centers, drill presses, and turret tooling setups. It features a 0.625 inch (5/8 inch) inside diameter and a 1.250 inch (1-1/4 inch) outside diameter, with a length under head of 3.250 inches (3-1/4 inch). The head thickness measures 0.265 inches. With a slot length of 2.875 inches (2-7/8 inch), this bushing provides the precise locating and retention geometry required for accurate tool positioning. Installation and setup are handled by machinists and CNC tooling technicians in production and job shop environments.

This Type C tool holder bushing is suited for rotary tooling applications where a slotted body style is required for positive drive and anti-rotation. It is commonly installed in gang tooling blocks, turret heads, and quick-change tooling systems found on CNC lathes and machining centers. The 5/8 inch bore accommodates tool shanks and drill bushings of matching diameter in standard production tooling configurations.

Key Features

• Type C slotted bushing design provides positive drive and anti-rotation in compatible tool holders
• 0.6250 inch inside diameter for precise tool shank fitment
• 1.2500 inch outside diameter for standard block and turret seat sizing
• 3.2500 inch length under head accommodates deeper tooling stack requirements
• 2.8750 inch slot length for full engagement with drive keys in mating holders
• Head thickness of 0.265 inches for positive axial stop at seating surface

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for Type C rotary tool holder systems requiring a 0.6250 inch ID and 1.2500 inch OD slotted bushing.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the tool holder or turret seat is clean and free of chips or burrs before seating the bushing. Confirm the slot in the bushing aligns correctly with the drive key in the mating holder to prevent rotation during operation. Follow the machine manufacturer's tooling setup procedures and applicable shop safety lockout/tagout protocols before servicing or changing tooling.
