Rustlick 74052 EDM-250 Grinding Fluid 5 Gal Pail

Product Description

The RUSTLICK 74052 is a water-soluble grinding fluid in the EDM-250 series, formulated for metalworking operations involving carbide and ferrous metal. Supplied as a green liquid in a 5-gallon pail, it is designed for use in surface grinding, cylindrical grinding, and EDM-adjacent machining processes. The fluid contains inhibitors that prevent cobalt leaching from all grades of carbide, making it a reliable choice for shops that regularly machine tungsten carbide tooling. Its highly biostable formula resists bacterial and fungal growth, extending sump life and reducing maintenance intervals for machine operators and shop technicians.

The 74052 is suited for production machine shops, tool and die operations, and grinding centers working with tungsten carbide inserts, carbide-tipped tooling, and ferrous workpieces. It also carries secondary utility as a cleaning fluid, adding flexibility in environments where multiple fluid types are consolidated. The 5-gallon pail format is practical for individual machine sumps or small-batch mixing at the point of use. This fluid meets OSHA standards and is appropriate for professional metalworking environments where fluid safety and sump longevity are operational priorities.

• Green liquid form for easy visual identification in sump and mixing
• Meets OSHA standards for metalworking fluid applications
• Suitable for secondary cleaning applications in addition to grinding use

Compatibility

Designed for use on carbide and ferrous metal substrates, with specific suitability for all grades of tungsten carbide. Compatible with grinding and EDM-type machining operations as identified by the EDM-250 series designation.

Installation Notes

This fluid is applied and maintained by machine operators or shop technicians familiar with metalworking sump systems. Follow the manufacturer's dilution ratio instructions before introducing the fluid to the sump. Drain and clean the sump of old fluid and residue before charging with fresh fluid to avoid contamination and premature breakdown. Consult applicable OSHA guidelines and local safety data sheet requirements for handling, storage, and disposal of metalworking fluids.
