EOC collet chucks with BT taper (MAS403) offer high precision, rigidity, and optimal torque transmission, making them ideal for high-performance CNC machining. Thanks to the symmetrical BT taper and EOC collets with a 6° closure angle, they ensure consistent clamping force and high concentricity. Available in BT30, BT40, and BT50 sizes, they are compatible with AD+B coolant, providing improved tool cooling and chip management. Their fast tool change and versatility make them perfect for high-intensity production environments.
The spindle is balanced G6,3 (15.000 r.p.m.).

EOC collet chucks with BT taper interface according to MAS403 (JIS B 6339) are engineered to deliver high performance on CNC machining centers, particularly in applications where precision and rigidity are essential.
The symmetrical profile of the BT taper, combined with the clamping action of the EOC collet system (with a 6° closure angle), ensures uniform and constant clamping force, minimizing vibrations and enabling optimal torque transmission.
Thanks to their balanced geometry and compatibility with automatic tool changers, BT spindle holders with EOC collets are a modern and widely adopted solution in CNC applications. The use of EOC collets guarantees high clamping force with certified concentricity, making them ideal for machining operations requiring stability and accuracy.
Available in multiple sizes (BT30, BT40, BT50), these holders are compatible with a wide range of machine tools. Additionally, they support coolant-through capability via the AD+B standard, enhancing tool cooling, chip evacuation, and overall machining efficiency.
Due to their simple and precise construction, EOC collets allow for fast and secure tool changes, even in high-throughput production environments. The AD+B coolant system makes these chucks suitable for high-performance machining with precise thermal control, extending tool life and improving the quality of the finished part.
