ER Collet
ER collet is a kind of cylindrical fixture, which is used to imprison drilling tools or milling tools. It can also be used to fix and reinforce a fixed locking device that needs to transform the processing parts. ER spring chuck, large clamping force, wide clamping range, good precision. It is widely used in boring, milling, drilling, tapping, grinding and carving. ER collet is a kind of spring collet, which is generally used for NC tool holders.

Product Details
ER collet is German standard, its taper is 16 degrees, mainly used for spring collet. ER collet is a connecting tool between the tool holder and NC tool. ER collet, commonly known as spring collet, is a kind of drill collet installed on the machine tool spindle. Its function is to lock the connection between the tool and the spindle. Er elastic collets made of bearing steel have high elasticity and service life. All Er elastic collets are precision ground and manufactured according to German din6499 precision specification. Er has 1 mm elastic space. Er collet uses the elastic deformation of a spring collet in the middle to clamp the tool. It is simple and convenient to clamp, and the accuracy of the tool handle is not high.
Advantages of ER collet
- It can improve the quality of part precision and surface roughness.
- It can extend the tool life and reduce vibration.
- Iit can reduce tool inventory.
Characteristics of ER collet
- Made of special elastic steel material.
- Power clamping ability, precise accuracy.
- Used for boring, milling, drilling, tapping, grinding and engraving operation etc.
