Castrol Honilo 909 is a low viscosity, chlorine- and heavy metal-free neat cutting oil for honing and finishing operations. It has been especially developed for honing and superfinishing of ferrous and non-ferrous materials and has also proven its performance in grinding, drilling and general machining of aluminium and yellow metals.
Applications
- Honing and superfinishing of cast iron, low and high alloy steels, nickel and chromium alloys
- Honing / finishing of aluminium and yellow metals
- Grinding operations on steel and cast iron components
- Drilling and general machining of aluminium and yellow metals
- Use in single sump machines and large central systems
Advantages
- Excellent flushing and lubrication properties help to extend honing stone and grinding wheel life and enable high surface finish and tight dimensional tolerances.
- Low viscosity and very good wetting characteristics reduce drag-out, resulting in lower top-up rates and reduced consumption.
- Good filtration behaviour and high oxidation stability increase fluid lifetime and support consistent process reliability.
- Chlorine- and heavy metal-free formulation supports an improved environmental profile and can help to reduce disposal costs.
- Low odour and light colour enhance operator acceptance and contribute to a clean working environment.
Application notes
- Best performance is achieved with clean, well-filtered oil and correct tool dressing parameters.
- Avoid contamination with other oils and prevent water ingress to maintain product stability.
- Delivered as ready-to-use neat oil – no dilution required.
FAQ – Frequently asked questions about Castrol Honilo 909
Which components are particularly suitable for Castrol Honilo 909?
Castrol Honilo 909 is particularly suitable for precision honed and ground parts made from cast iron, low and high alloy steels, nickel and chromium alloys as well as aluminium and yellow metals, for example in automotive, hydraulic and general engineering applications.
Can Honilo 909 be used for several operations in one system?
Yes, due to its excellent flushing and multi-metal capability, Honilo 909 can be used not only for honing and superfinishing but also for grinding, drilling and general machining, allowing you to consolidate products on the shop floor.
What are the benefits of the chlorine- and heavy metal-free formulation?
The chlorine- and heavy metal-free formulation improves the environmental and health profile of the fluid, helps you to comply with legislative requirements and can reduce waste treatment and disposal costs while maintaining high machining performance.
