CASTROL ILOCUT 820
Castrol Ilocut™ 820 is a chlorine and heavy metal-free neat cutting oil designed for general machining and grinding across a wide variety of ferrous metals. Formulated with a unique combination of ester, extreme pressure additives and base oil, Ilocut 820 offers optimised machining operations and improved surface finish in the deep drilling of ferrous metals, low and medium-alloyed steels.
The fluid’s ability to support stable machining performance across turning, drilling, milling, honing and grinding helps manufacturers to maintain consistent output, and strong oxidative stability keeps the fluid performing at its best for longer.
By reducing heat generation and maintaining surface integrity during continuous production, it reduces operating costs and is the ideal neat cutting oil for cast iron and alloyed steel products. Castrol Ilocut 820 is compatible with a range of products and medium-alloyed steels, and works alongside other neat cutting and grinding fluids, allowing users to build a complete metalworking portfolio through Castrol's range of general machining and cutting oils.
Why Choose Castrol?
Formulated with highly refined mineral base oils, Castrol Ilocut 820 is designed to optimise machining performance and enhance surface finish through advanced and reliable lubricity at the cutting edge. It is engineered for grinding and general machining. Its clean-running nature supports efficient chip flow and contributes to a tidy working environment, while its compatibility with many machine tool materials makes it suitable for mixed-metal workshops.
Superior additive technology leads to extremely high cutting and grinding efficiencies, extended tool life, enhanced surface finish and lower overall operating costs. With high performance under extreme pressure, Ilocut 820 increases tool life by protecting key components from general wear and tear.
Operators working with aluminium alloys benefit from its stain-free performance, while those machining steels gain from the fluid’s inherent lubricating film, which helps protect tools under higher loads. By supporting both precision and durability, it aligns well with demanding production environments where tool life and surface quality matter. Low oil mist, even at high pressures and flow rates, leads to a reduction in oil consumption and increased production rates, while effective filtering characteristics deliver strong performance across the drain interval.
Why Choose Broughton Lubricants?
With over 100 years in the business, Broughton Lubricants can advise on the best Castrol metalworking fluids for your machinery and materials based on a discussion of your technical needs. With decades of experience, our technical experts can help you to identify direct replacements for discontinued or rebranded fluids, or those that have been reformulated or upgraded and are therefore hard to find or unsuitable for your needs. Where direct replacements are not available, we can guide you through the process of choosing a suitable alternative. As the UK’s only Castrol Ambassador Distributor for both industrial and automotive ranges, we offer informed support alongside reliable nationwide supply.
