Characteristic

Model : 3X5FT

The FT series spindle grippers are designed to match 25° taper holders (BT, CAT, DIN), utilizing an internal clamping structure at 15° for enhanced clamping force with minimal travel. They feature robust construction optimized for high-pull-force, short-stroke, and high-rigidity applications.

Compatible with MAS BT, ASME CAT, and DIN 69872 standards
15° clamping angle ensures efficient force transmission
Threaded interfaces range from M10 to M30 depending on size
Excellent for high-speed machining, heavy-duty tool holding
Hardened components for increased durability and stability
