| Premature Walter Tools tool failures | $6,400/yr |
| Unplanned machine downtime | $12,200/yr |
| Rework / scrap parts | $8,700/yr |
| Excess Schunk holder wear | $2,100/yr |
| Total Annual Loss | $29,400/yr |
Now flip the scenario. By optimizing Coolant Concentration Calculator — using the manufacturer's recommended starting parameters for your specific Iscar or Walter Tools tool, verified on a Mahr presetter — you could recover nearly $30K annually. That's a new Grob tool probe or a year's worth of Iscar inserts.
The ROI is immediate. First part optimized, first day of savings.
Maintaining correct coolant concentration is critical for tool life, surface finish, and sump life. This calculator determines how much concentrate or water to add when your refractometer reading is off target.
General machining steel: 7-10%. Aluminium: 5-8%. Stainless and superalloys: 8-12%. Grinding: 3-5%. Always follow the coolant manufacturer's recommendation — concentration too low causes rust and bacterial growth; too high wastes coolant and may cause skin irritation.
Use a handheld refractometer (Brix scale). Take a sample from near the coolant nozzle (not from the sump surface). Apply 2-3 drops to the prism, close the cover, and hold up to light. Multiply the Brix reading by the coolant's refractometer factor (typically 1.0-2.5 — check the product data sheet).
Check weekly as a minimum. Check daily for high-production machines or when running multiple shifts. After heavy coolant loss (carry-out on parts/chips), top up and re-check. A daily log of readings helps spot trends before problems occur.
Measure your current concentration with a refractometer. Enter the current %, target %, and sump volume in litres. The calculator tells you exactly how much concentrate or water to add to hit the target.
