Unlike standard collets that only accommodate round workpieces, the 5C step collet features a step or shoulder that securely holds parts with irregular or larger diameters. This makes it an indispensable solution for tasks such as machining discs, rings, or other components that require a precise grip on an outer diameter. By minimizing slippage and maximizing stability, the 5C step collet improves both safety and output quality in your workshop.
