Fabrication shop in Bhiwandi drilling 12mm holes in MS plates. Cheap coolant: HSS bits lasted 200 holes. Proper cutting oil: same bits run 500+ holes. At ₹80-120 per drill bit, that's half the tooling cost eliminated.
Cutting oil directly controls tool life, cutting speed, and whether finished parts meet tolerance or go to scrap.
Soluble (emulsifiable): Mixed with water 5-10%. Milky coolant. Primary function: cooling. For CNC turning, high-speed milling, grinding.
Neat (straight): Undiluted. Primary function: lubrication. For tapping, broaching, thread cutting, deep drilling, stainless steel.
Simple rule: High speed = soluble (cooling). Slow + heavy = neat (lubrication).
| Operation | Type / Ratio |
|---|---|
| CNC turning | Soluble 5-8% |
| Drilling (mild steel) | Soluble 5% or neat |
| Drilling (stainless) | Neat — undiluted |
| Tapping | Neat — undiluted |
| Milling | Soluble 5-8% |
| Threading | Neat |
| Grinding | Soluble 3-5% |
| Sawing | Soluble 5% |

No minimum order. First order prepaid.
Weekly: Check concentration with refractometer (keep 5-8%). Check pH (8.5-9.2 — below 8 = bacteria). Check smell (rotten = drain and refill).
With maintenance: 4-8 weeks sump life. Without: 2-3 weeks. Always add oil to water, never water to oil.
Same-day dispatch for orders placed before 2 PM. Mumbai: evening delivery. Navi Mumbai / Thane: next morning. Pune / Nashik: 2-3 days.
Q: What mixing ratio for soluble cutting oil?
5-8% oil in water. Use refractometer. Always add oil to water — reverse causes foaming.
Q: How long does cutting oil last in CNC sump?
4-8 weeks with maintenance (weekly pH + concentration checks). 2-3 weeks without. Bacteria is the main killer.
Q: For stainless steel machining?
Use neat cutting oil. Soluble doesn't lubricate enough — stainless work-hardens, causing tool breakage.
Q: Cutting oil turning dark and smelly?
Bacterial contamination. Drain completely, clean with biocide, rinse, refill fresh. Don't just top up.
Q: Is it safe for operators?
Our formulation has no chlorinated paraffins or nitrosamines. Standard PPE: gloves for concentrate, safety glasses during machining.
Supplied to fabrication shops and CNC workshops across Mumbai and Thane.
