5C collets, also known as 385E collets, are a popular alternative to standard 3-jaw chucks for holding cylindrical workpieces up to 1-1/8” or 28mm, and bar stock up to 1” or 25mm in diameter. Collets are easy to change out, allowing faster set-up times, and they provide 360-degree support for the workpiece for higher accuracy. These collets provide a much stronger grip and superior concentricity than a standard 3-jaw chuck.

 

Collet Selection Guidelines:

• Collets are available individually or in kits
• Collet series is determined by the internal surface and shape (smooth or serrated round, square, hexagonal, etc.)
• Collet bore diameter is determined by the workpiece diameter

 

Round 5C Collets:

• Can be used to hold any type of round or odd-shaped material
• Strong grip of material for a variety of machining applications
• Provide 360-degree support for the workpiece
• High accuracy and concentricity
• Repeatable and easy to use

 

5C Round Collet Clamping Range (Inch):

• 1/16" to 1-1/8" in 1/64" increments

 

5C Round Collet Clamping Range (Metric):

• 3mm to 28mm in 0.5mm increments
