Product Description

Hocut 4640 is an advanced, high lubricity, clean-running soluble oil metal removal fluid specifically formulated to be very low foaming and rapid in degassing. It is an excellent universal coolant capable of working in many heavy duty machining and grinding applications for a wide range of metals including high or low carbon steels (e.g. 1018), alloy steels such as 4130 and 4140, cast iron, nodular and gray iron, 300 and 400 series stainless steel, automotive grade cast aluminum alloys including 308, 319, 356, 380, 384, 390, and 6061.

Hocut 4640 has been specially developed to perform well in high pressure operations. It has a very low propensity to foam and rapidly degasses entrained air therefore eliminating the need for repeated sump side addition of defoamer. These properties make Hocut 4640 the ideal coolant for high energy central sumps with minimal coolant rest time.

Hocut 4640 is clean running and biostable assuring long, odor-free sump life and is suitable for both centralized systems and single-sump machines. Hocut 4640 provides high corrosion protection without staining and lubricates machine ways and indexing mechanisms.

Features & Benefits

  • Enhanced lubricity technology improves plant economics:
    • Extends tool life
    • Improves productivity – reduces cycle time
    • Provides superior surface finish - reduces rework and scrap rates
    • Lower running concentration reduces coolant usage
  • Excellent corrosion protection for ferrous and aluminum alloys
  • Multi-metal compatible: One product satisfies all machining requirements on automotive grade steels and aluminum alloys
  • Biostable formulation extends sump life. Minimizes waste treatment, disposal, and recharge costs. No repeated need for sump-side additives.
  • Clean-running: High detergency keeps wheels and machine surfaces clean thus minimizing maintenance downtime.
  • Low foam: Ideal for high feeds and speeds and high pressure applications. Rapidly degasses entrained air.
  • Compliant with: TSCA and DSL
  • Free from boron, formaldehyde releasing agents, secondary amines, chlorine, phenols
