What Are 5C and 16C Collets: A Complete Guide to Two Classic Workholding Systems
The 5C and 16C collets are two of the most widely used American standard collet systems in the precision machining industry. They are designed to provide reliable, accurate, and repeatable workholding for cylindrical components. Both models operate based on the principle of elastic deformation, using spring tension to generate strong and uniform clamping force. Because of their high concentricity and stable performance, these collets are essential in turning, milling, and grinding operations that demand precision and efficiency. 5C and 16C Collet Chucks Overview The 5C collet chucks and 16C collet chucks are designed to fit different machine sizes and spindle interfaces. Their clamping capacities are defined in inch measurements. The 5C collet can hold workpieces up to approximately 1.125 inches (28.5 mm) in diameter, while the 16C collet offers a larger capacity of about 1.625 inches (41.3 mm). In terms of performance, the 5C chuck is commonly used for light-duty or ...
