Mike-O-Drill DH-60 is a heavy duty, light viscosity cutting oil. Sulfurized and chlorinated extreme pressure additives provide hydrodynamic and polar lubrication. This product is recommended for screw machines, chuckers, band saws, and bar machines. Mike-O-Drill outperforms other cutting oils in deep hole drilling, heavy cutting, drilling, sawing, and other difficult operations. It is ideal for both ferrous and non ferrous materials. Staining may occur on copper if the part is not rinsed soon after machining.
