5C Collets- Hardened and Ground

Dunham Tool precision 5C collets are available in both inch and metric sizes. Collets in round sizes are 1/16" to 1-1/16" in 1/64" increments, or 3mm to 26mm in 1mm increments; 5c square and hex collet sizes are 1/8" to 11/16" in 1/16" increments.  

These collets can be used with Dunham Tools standard 5C collet fixtures and spindles as well as other manufacturers’ R8 and 5C fixtures. The standard hardened and ground 5C and R8 collets (contracting style) are manufactured with the same high quality standards built into all Dunham Tool products.

Dunham can also supply a new adjustable collet / workpiece stop with these collets and collet stops are available, either as an attachment to the Dunham Tool collet or the Dunham air collet closer.

5C collets can be used in all Dunham 5C collet chucks, air collet chucks, precision spindles and collet actuators. These collets can also be used in any other manufacturers' 5C collet fixtures, 5C spindles, etc.  Dunham Tool collets are designed for precision workholding applications that require holding a workpiece on an outside diameter. These collets are typically used with either hydraulic or pneumatic actuators and represent a low cost, accurate and fast workholding method for lathes, grinders, machining centers, milling machines, etc.
