The ER collet chuck with BT30 Dual Contact interface is an advanced solution for clamping cylindrical shank tools, ensuring high precision and reliable performance even in demanding machining operations. Designed according to DIN ISO 15488-B standards, this system takes advantage of the versatility of ER collets, which allow clamping of tools with different shank tolerances, providing great operational flexibility and reducing the need for dedicated toolholders.

Tecnichal data:

The BT30 Dual Contact interface ensures simultaneous face and taper contact with the machine spindle, which increases overall rigidity, improves torque transmission, and minimizes micro-vibrations during machining. This results in higher process stability and superior surface finishes, making it ideal for applications in precision engineering, aerospace, automotive, and mold manufacturing, where strict dimensional and quality requirements are critical.

The ER collet chuck with BT30 Dual Contact is balanced to G2.5 grade, ensuring stable performance even at high rotation speeds up to 25,000 rpm. This makes it particularly suitable for high-speed cutting (HSC), where balancing and vibration reduction are essential to preserve tool life and maintain high levels of accuracy.

The clamping nut, supplied as standard, ensures secure and uniform tool clamping, contributing to greater stability during cutting and simplifying tool setup and replacement. The combination of BT30 Dual Contact interface, ER collet system, and high-quality construction provides a reliable, precise, and durable toolholder, designed to deliver consistent performance both in high-volume production and in specialized, complex machining tasks.
