Castrol Variocut B 27 is a chlorine- and heavy-metal free high performance neat cutting oil. It is specifically designed for broaching and gear cutting of steel and cast iron and provides excellent load carrying capacity, surface finish and extended tool life. The formulation contains active sulphur and is therefore not compatible with yellow metals.
Applications
- Broaching and gear cutting of steel and cast iron
- Gear hobbing of steel and cast iron gears
- Gear shaping operations on steel and cast iron components
- Grinding of steel and cast iron
- Note: Not suitable for yellow metals (e.g. brass, bronze, copper alloys) due to active sulphur.
Benefits
- Advanced EP additive technology delivers excellent lubricity and extended tool life.
- Improved surface finish and increased cutting speeds support higher process efficiency and productivity.
- Chlorine- and heavy-metal free formulation improves the environmental profile and reduces disposal costs.
- Good flushing and cooling performance helps chip evacuation and reduces thermal load on the tool.
Application notes
- Use neat, without dilution.
- Optimised for broaching and gear machining of steel and cast iron.
- Avoid contact with yellow metals – no approval for these materials.
FAQ – Frequently asked questions about Castrol Variocut B 27
For which components is Castrol Variocut B 27 particularly suitable?
Variocut B 27 is ideal for broaching and gear machining of steel and cast iron parts, including gear hobbing, gear shaping and grinding operations.
Can Variocut B 27 be used on yellow metals?
No. Due to its active sulphur content, Variocut B 27 is not compatible with yellow metals such as brass, bronze or other copper alloys.
What are the main advantages of the EP additive technology?
It reduces tool wear, allows higher cutting speeds and improves surface finish, resulting in stable processes and lower machining costs per part.
