Bore bar S12M-STUPR11 S16N-STUNR16 spring steel CNC inner hole turning tool machining center

Adopting modular interface design, compatible with mainstream lathe systems, the heat treatment process of spring steel material makes the tool holder both tough and wear-resistant, especially suitable for long cutting depth working conditions of difficult to machine materials such as stainless steel and alloy steel. The stress relief groove design inside the tool holder further enhances the anti vibration ability, extends the tool life, and reduces harmonic resonance phenomena during machining.
