V-752 Vertex collet chuck set — ER‑20, SK‑40-70L

The V-752 collet chuck set provides secure toolholding for milling and drilling operations where repeatable concentricity and robust spindle interface are required.

• ER‑20 compatibility for standard toolholding
• SK‑40 taper for rigid spindle fit
• Complete collet set included

Consistent clamping for repeatable machining results

A high‑precision collet chuck with ER‑20 clamping reduces runout and improves repeatability, which directly benefits surface finish and tool life. The clamping system converts axial and radial loads into a concentric hold, so cutters and drills remain stable under cut. For production shops and maintenance departments, this stability translates into fewer rejects and longer uninterrupted machining runs.

Secure spindle interface for heavy and finish machining

The SK‑40 taper specified as SK‑40-70L ensures a tight, taperled connection between the spindle and the chuck, delivering enhanced rigidity and torque transmission. This interface is particularly advantageous during heavier milling passes or finish operations where vibration control and concentricity are critical. The taper length supports precise axial positioning and simplifies regripping procedures when tool changes are required.

Ready-to-install collet set to reduce downtime

Supplied as a ready set, the chuck arrives with the matching collets to allow immediate installation and operation. Quick clamping and release of tools speed up changeovers and help maintain production flow without lengthy setup. Metav’s technical team can advise on collet selection and compatibility to match specific tool shanks and machine spindle requirements, supporting efficient integration into existing tooling systems.
