Collets for tooling systems are mainly used for holding cutting tools, and the form has single taper and double taper.

These collets can hold in parallel even if cutting tools have dimensional variation in outside diameter, since there are flexing slots from both sides of front and back.

It is not suitable for holding a workpiece since less clamping range in a free state can be taken as compared with draw back type collets.

Collets for air tools are used by attaching to air tools, and holding a drill bit or a grinding wheel.

Collets for air tools have a type tighten with a hexagonal wrench, or a type which pushes collet by the nose cap.

High precision is not expectable due to structural feature.
