Collets & Holders for Toolholding
 

Crawford manufacture & supply a wide range of toolholders and toolholding collets which are directly interchangeable with other proprietory systems.
The ECX Collet system uses single angle collets which are available in metric sizes, and can accommodate a range of 0.5mm on bores under 3mm and 1mm on larger diameter bores (except ECX 50). The Double Angle Collet system utilizes the double angle collets which are available in metric sizes, by 0.5mm increments, or imperial sizes in 1/64" increments. Each collet can accommodate a 0.5mm dia collapse.
The YCC Collet system finds general application in driven/live tooling of Japanese origin. They can easily be mistaken for ECX types and are not interchangeable. They are available in metric sizes. The Supergrip Collet system utilizes the single angle collets which are again available in metric sizes by 0.5mm increments and imperial sizes in 1/64" increments. Each collet can accommodate a 0.4mm dia collapse.
DIN 6388 Collets are used in milling and drilling applications in equipment of European origin. They are available in metric sizes. The R8 Collet is specific to Bridgeport and similiar types of milling machines. They are used for general purpose milling and drilling operations. R8 Collets are available in imperial and metric milling cutter sizes.
DIN 6345 Rubberflex Collets are used in tapping heads to centralize and retain taps. The mechanism is provided with a separate driver to transmit the cutting torque. They are also used in some toolholders for light duty drilling applications. They are available in metric sizes.
