Increase the reach of your modular tool assemblies while preserving absolute structural rigidity and centerline precision with heavy-duty Extensions. Specifically engineered for deep cavity pocketing, high-walled workpiece profiling, and complex mold manufacturing, these modular adapters act as a bridge between the base machine spindle holder and the final cutting unit. Featuring precision-ground location faces and high-strength interlocking keys or locking mechanisms, this rigid extension setup dampens harmonics and prevents tool holder deflection under heavy cutting forces.
