The term “collet” is derived from the French word “collet” which means “collar” or “neck”. It is a type of holder or device used to grip, hold, and secure parts in a machine or tool. In machine tools, collets are used to hold cutting tools such as drill bits, reamers, taps, and end mills, and are also used to hold workpieces in place.

A collet is composed of two parts: the body and the sleeve. The body is generally a circular or hexagonal shape and is made of steel or other metal, with a bore in the center that matches the diameter of the material to be held. The sleeve is a cylindrical or tapered sleeve which fits into the bore of the body, and is also usually made of steel or other metal. The sleeve has an internal thread, which is used to secure the collet to a machine spindle or other tool.

Collets can be divided into two categories: static and dynamic. Static collets are designed to be used in a stationary position, such as holding a drill bit for drilling. They are usually made of steel and are designed to be tight fitting. Dynamic collets are designed for use with rotating machinery, such as a lathe. They are usually made of brass or similar material and are designed to have a certain degree of “slip” in order to allow for accurate and precise positioning.

Collets are used in a variety of industries, including aerospace, automobile, medical, and manufacturing. In aerospace, collets are used to hold and secure fasteners, such as bolts and screws, in place. In the automobile industry, they are used to hold and secure spark plugs, valves, and other engine components. In the medical field, they are used to hold and secure delicate medical instruments. In manufacturing, they are used to hold and secure workpieces in place for milling, drilling, and other machining operations.

Collets are often chosen for their ability to provide an accurate, secure grip on a workpiece. This is especially important when precision machining operations are being performed. They are also chosen for their ability to reduce vibration and chatter, which can reduce the quality of the machined product. Additionally, collets are often chosen for their ability to reduce the amount of time required to set up and adjust machinery.

Overall, collets are an important tool for many industries, and are often used to ensure accuracy and reduce setup time. Their ability to provide an accurate and secure grip on a workpiece, as well as reduce vibration and chatter, makes them a valuable tool in many machining operations.
