Precision Collet, Milling Collet

A collet is a kind of chucks used for fixing drilling or milling tools onto milling machines. We have nearly 20 years of experience with producing collets including our ER collet, TG collet, SK collet, 5C collet and other collets. If the types of collets displayed here fail to satisfy your needs, please contact us and we can customize collets for you according to your samples. All the collets will be qualified before leaving our factory and the accuracy will be within 0.003mm.

    2. ER ColletThe ER collet system is the most widely used tool holding system in the world. Installed on the milling machine, it is a cylindrical chuck which is used to fix drilling bits or milling tool. ER collets are used in the various machining processes, such as boring, milling, reaming, tapping and grinding. Read More
    2. Coolant ER Steel Sealed ColletThe steel sealed coolant collet is also called an ER coolant sealing collet or steel sealed collet. With rubber seals attached to it, this kind of collet does not require the installation of discs, plugs or other special hardware. Also, coolant is sealed in the collet, therefore...Read More
    2. ER Tap ColletWe can provide various types of ER tap collets for you, like the ER8 collet chuck, ER11 collet chuck, ER16 collet chuck, ER20 collet chuck, ER25 collet chuck, ER32 collet chuck and ER40 collet chuck.

    2. TG ColletWe can provide all types of TG collets for you, including TG75, TG100 and TG150 collets. These collets are all made of spring steel alloy. After being hardened, they are the ideal choice of high-speed and high-accuracy milling and boring tools. Precision TG coolant collets can be interchanged with... Read More
    2. SK ColletThe SK collet is widely used in high-speed milling, drilling and reaming. It has an 8°cone angle, the smaller the cone angle, the higher the concentricity of collet. When clamping, the SK collet will produce strong force, making it easier to be put into tool carrier...Read More
    2. 5C ColletThe 5C collet is the standard type commonly used in lathe, which is very similar to R8 collet, making it an ideal choice of drilling and milling. All types of 5C collets are provided by LONNZ. Also, a 5C collet can be used in all the 5C collet chucks, air collet chucks, precision spindles and collet actuators.Read More
    2. DA Double Angle ColletThe DA (Double Angle) collet is usually used for drilling and milling, especially for machining processes the require collets with short diameters, such as multi-axis drilling in precision manufacturing center. The raw material and processed materials of collet have a significant impact on the quality of the collet... Read More
    2. OZ ColletThe OZ collet is a kind standard type used for Perske spindles. The precision OZ collet is essential for providing the correct size collet for the tool shank diameter. Part of the parameters of OZ collet are displayed below. If you need detailed information, please contact us. Read More
    2. R8 ColletThe R8 collet is commonly used to fix the cutting tool shank and it can also be used in milling machines, drilling machine, CNC machining centers, R8 precision spindles and R8 collet fixtures. What’s more, cutting tools can be rapidly changed when using an R8 collet. We can provide all kinds of R8 collets for you to choose from. Read More
    2. Specific colletsApplication: Davenport collet is used in davenport machine tools.
      Material: 9CrSi from BaoSteel, SUG2 from Japanese spring steel
      Accuracy: The accuracy of this collet reaches the collet standards of Japanese AA level machining tool and the concentricity can reach 0.003mm.       Read More
