MQL & EDM Fluids — Hyspray and EDM Dielectrics

Dry-machining lubricants that deliver coolant-level performance with near-zero fluid consumption, plus high-purity dielectric fluids for EDM.

Quick Answer

Castrol Hyspray Minimum Quantity Lubrication (MQL) fluids and EDM dielectric oils for advanced manufacturing. MQL is the green-machining alternative to flood coolant — Hyspray vegetable-based fluids deliver 5-50 mL/hour through MQL nozzles for steel, aluminium and stainless turning/milling. EDM dielectric oils — Castrol's specialty range — chosen for spark-machining of dies, moulds and aerospace components.

Our Bhimavaram warehouse stocks the complete mql & edm fluids range for 48–72 hour delivery across AP, and our technical team is available on-site for application trials, coolant sampling, and training. Paired with our CoolantCare fluid management programme, you get not just a supplier but a lubrication partner committed to lowering your total cost of lubrication.

Frequently Asked Questions

What are the benefits of moving from flood coolant to MQL?

Fluid consumption drops by 95%+, parts come off the machine dry (no wash step), chips are recyclable without degreasing, and coolant-disposal costs disappear. MQL suits aluminium aerospace and automotive components best.

How often do I change EDM dielectric?

For sinker EDM, 6–12 months with good filtration. For wire EDM, dielectric is continuously filtered and topped up rather than changed.
