NF 99 is a heavy duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 99 contains chlorinated additives, fatty oil and special lubricity fortifiers to impart quick release of chip from tool even under extreme high cutting pressure. The low viscosity ensures good cooling and flushing properties, which are essential for high speed machining.

NF 99是一款专为非铁金属而配制的切削油，适用於铜金属、铝金属及其合金的重负荷切削，含有氯化物、脂肪及特殊润滑添加剂，增进其极压及润滑性能，就算在高切削压力下，也能使屑片容易与刀具分离，低的黏度确保了足够的冷却及冲屑性能，都是高速切削所必需。
