Collets
For over four decades, we have been developing customized, efficient solutions for the metalworking sector. Two of them are our JBS double cone and pull collets.
Our Double Cone And Pull Collets
The original directly from the manufacturer
The selection of the appropriate collet depends on the material to be processed and its diameter. Our collets are suitable for all kinds of materials, such as plastics, high-alloy chrome steels and steel according to DIN 1013, whether grinded or rolled. They run synchronously with the jackscrew and adapt to the material during machining. Changing the collets is fast and takes only 2-3 minutes, eliminating the need for complicated adjustment.
More than 6,000 collet models on demand
You need a flexible collet – we deliver! In our large warehouse in the north of Germany, more than 6000 different collet models are waiting for your order. And if it has to go really fast, we offer overnight and express shipping.
Contact us and we will be happy to advise you!
Our perfectionist
The Pull Collet
Our pull collet is suitable for all JBS Guide Bushing Systems. It consists of 3 segments held by springs and O-rings. Due to the higher concentricity and rigidity during milling, a better surface quality of the components is achieved. The lower contamination of the collet compared to the double-cone system ensures longer service life and lower maintenance work.
Our All Rounder
The Double-Cone Collet
The double cone collet is perfect for processing high quality materials with high tolerances. It can be used as a clamping and guiding collet and consists of 3 segments. The flexible collet is held by springs and gripping rings and the adjustment range is ± 0.4 mm. Buy the original at the best price from the manufacturer, that’s us!

Increased concentricity for your collets
TRA – this means true running accuracy and describes our high-precision collets, based on DIN 6499. We offer all collets in the variants standard and TRA, so you always have the right product for your next order. A JBS collet has a maximum runout of 0.02mm. If you want it to be even more precise, we offer the TRA variant with a max. runout of less than 0.01mm.
All TRA collets are available as pull or double cone variant.
