Consistent precision for repeatable machining results

The ER‑20 collet system delivers precision and low runout for consistent part quality. Designed to centre the tool shank precisely, the system reduces vibration and improves surface finish, which leads to fewer rejected parts and shorter rework cycles. For shops aiming to increase throughput, the proven clamping geometry of this solution helps maintain tight tolerances across repeated operations while supporting standard tool shank diameters.

Fast, flexible setup with MT‑3 compatibility

The inclusion of an MT‑3 taper arbor simplifies machine integration and reduces changeover time. The arbor enables direct mounting in spindles or adaptors that accept Morse taper sizes, giving versatility across machines. Supplied as a complete set with 10 collets, the kit minimises the need for multiple single purchases and supports quick tool changes, which is particularly useful for job shops and production lines that require flexible fixturing and efficient workflows.

Reliable workshop performance and practicality

Manufactured by Vertex and supplied as a ready-to-use kit, this clamping solution supports stable production routines and straightforward maintenance. The set is suitable for standard milling and drilling applications where secure tool retention and repeatability matter. Routine cleaning and correct engagement of the collet in the nut ensure ongoing repeatability and safe operation, contributing to predictable machine performance and lower process variability.
