5C Pneumatic Pull-Back Fail-Safe Collet Block

The Hardinge 5C (2-3/16-10) threaded-nose Collet Block accepts an entire array of workholding products. Standard 5C collets, collet stops, Dead-Length® collets, step chucks, Sure-Grip® expanding collets and manual chucks will thread onto the spindle nose for increased capabilities. Collets and other tooling sold separately. Air is required during setup whether using a single collet block or a subplate full of collet blocks. The fail-safe design does not require air during the cutting process. This results in maintained concentricity without downtime or waste if loss of air should occur. The Hardinge base design is open, allowing coolant and chips to be blown out rather than building up. This eliminates the need to tear down and clean out the unit. Modular units can be used vertically or horizontally for machining or assembly operations.
