To maximize efficiency, machine shops require coolants that are capable of working in diverse applications and on a wide variety of metals. Hocut 400K from Houghton International is a heavy-duty, chlorine-free machining and grinding metalworking fluid that can be used with many machines, including bar machines, lathes, chuckers, and centerless and cylindrical grinders.

Using Hocut 400K helps manufacturers gain cost-efficiencies by reducing the number of different metalworking fluids in their inventory. Because it can be used on many metals, it removes the need for changeover, promoting decreased downtime. The coolant provides in-process corrosion protection for machinery and parts without staining, and it extends tool life by offering good lubrication for machine ways and indexing mechanisms. Hocut 400K is clean running and low foaming, which contributes to reduced disposal costs and increased operator acceptance. Its biostable formula also ensures long, odor-free sump life.

Hocut 400K is especially suitable for machining automotive-grade aluminum cast alloys, including 308, 319, 356, 380, 384 and 390. It is also recommended for machining the following metals:

  •          High- and low-carbon steel;
  •          Alloy steels (4130 and 4140);
  •          Cast iron, nodular iron and gray iron.
