Industrial Coolants — Soluble & Synthetic Metalworking Fluids

Water-soluble, semi-synthetic and fully-synthetic coolants engineered for every machining operation — from heavy-duty turning to precision grinding.

Quick Answer

Castrol industrial coolants — Hysol SL XBB (water-soluble mineral), Syntilo 9930 (fully synthetic), Syntilo R (semi-synthetic), Alusol SL 51 XBB (aluminium-specific), Hysol MB 20 (chlorine-free) and Performance Bio NC Plus (bio-stable synthetic) — cover every machining operation from CNC turning and grinding to aluminium processing. Vasundhara Specialities supplies the full range across AP and Telangana with on-site CoolantCare fluid-management support that typically extends sump life from 6 weeks to 6 months.

Product Range

Hysol SL XBB

Water-soluble mineral coolant

Premium soluble oil for CNC turning, milling and grinding of ferrous metals. Chlorine-free, extended sump life, compatible with cast iron and steel alloys.

Hysol MB 20

Chlorine-free soluble

Biostable soluble oil for general machining with excellent rust protection on machine tools and parts.

Syntilo 9930

Fully synthetic coolant

Synthetic coolant for high-speed machining — grinding, honing, broaching. Exceptional transparency, extended sump life, low foam.

Syntilo R

Semi-synthetic emulsion

Semi-synthetic for mixed-metal machining and multi-operation shops. Balances lubricity and cooling.

Alusol SL 51 XBB

Aluminium-specific soluble

Purpose-formulated soluble oil for aluminium and aluminium-alloy machining. Prevents staining and pitting on aerospace-grade and die-cast components.

Performance Bio NC Plus

Bio-stable synthetic

Long-life synthetic for modern machining centres requiring low-maintenance fluid management.

Typical Applications

CNC turning and milling of steel, stainless and cast iron
High-speed grinding operations
Aluminium and aluminium-alloy machining
Aerospace, auto-component and die-casting shops
Central coolant systems and individual sumps

Frequently Asked Questions

Which coolant should I choose for aluminium machining?

Alusol SL 51 XBB is Castrol's dedicated aluminium-safe coolant. It prevents the staining and pitting that generic soluble oils can cause on aluminium-alloy parts.

How is Syntilo 9930 different from Hysol SL XBB?

Hysol SL XBB is a water-soluble mineral-oil-based coolant, ideal for general-purpose turning and milling. Syntilo 9930 is a fully synthetic coolant that forms a clear solution in water — preferred for grinding, high-speed machining and applications where tool visibility and sump life matter most.

Do you supply in 20-litre and 210-litre packs?

Yes. Standard pack sizes across the coolant range are 20 L pails and 210 L drums; 5 L packs are available for select SKUs on request.
