Protect unused CNC lathe turret stations from metal chips, abrasive debris, and high-pressure cutting fluids with industrial-grade Blanking Plug Holders (VDI protection plugs). Manufactured in accordance with strict DIN 69880 standards, these heavy-duty steel plugs feature a precision-ground VDI serrated shank engineered to seal unused turret ports seamlessly. By maintaining internal cleanliness and preventing coolant splash-through, they protect precision turret mechanisms from premature wear and corrosion, ensuring long-term operational reliability across demanding production environments.
