Castrol Syntilo 9974 BF, 208L

Castrol Syntilo 9974 BF is a boron- and chlorine-free synthetic coolant specifically formulated for heavy-duty machining and grinding of ferrous metals. Designed to meet the demands of modern high-speed and high-feed machining environments, it offers excellent lubrication, superior corrosion protection, and extended fluid life in both central and individual systems. Ideal for replacing neat cutting oils in applications such as gun drilling, gear hobbing, and broaching.

Application:

Castrol Syntilo 9974 BF is recommended for use in honing, milling, turning, boring, drilling, tapping, gear hobbing, and broaching operations. It is also highly effective in various grinding processes involving all ferrous metal alloys, including challenging materials like Inconel and titanium.

Advantages and benefits:

• Outstanding machining performance: especially on difficult-to-machine ferrous alloys.
• Low foaming characteristics: suitable for a wide range of water hardness conditions.
• Microbial resistance: extends coolant life in both central systems and individual machine sumps.
• Efficient tramp oil separation: enables easy removal and maintains fluid stability.
• Environmentally friendly: free from boron, chlorine, phenol, and nitrites.
• Excellent corrosion protection: even in hard water environments.
• Neat oil replacement: superior lubrication package allows elimination of conventional neat oil technologies.

Classification according to standards:

• DIN 51385 – corrosion inhibition standard for water-miscible fluids.
• ISO 6743/7 – classification: ISO-L-MAF (synthetic fluid for metalworking operations).

Approvals and certifications:
Castrol Syntilo 9974 BF complies with industry best practices for health and environmental safety. It is engineered for use in modern machining centers and meets internal technical benchmarks for sustainable production and reduced waste management needs.
