Collet chucks for high-speed milling


Wednesday 15 July 2026, 8:00:00 AM


Seco has enhanced its ER HP Collet Chuck range, setting a new benchmark for high-speed milling and 5-axis machining. With a finely balanced, rigid design, the latest ER HP delivers smoother surface finishes, longer tool life and reliability across the most demanding applications.


Modern machining environments leave little room for error. Tool slippage, vibration and unreliable clamping all translate into costly downtime and wasted material. The ER HP Collet Chuck has been engineered to eliminate these risks. Its run-out accuracy, combined with a robust, symmetrical build, ensures consistent results, reduced tooling costs and faster cycle times. High clamping force and a secure grip maintain full process security, even during heavy-duty cutting operations.


Just as importantly, the ER HP is straightforward to adopt. Where complex toolholder systems often demand specialised training or risky set-up procedures, the ER HP relies on a simple roller key for installation. The result is fast, safe changeovers that keep spindles turning and downtime to a minimum.
