Shop soluble oils
Choose by application
Start with the material, operation and cutting severity. Then consider surface finish, dimensional tolerances, sump life, water quality and any cleaning or finishing steps that follow machining. QA can help match the formulation and working concentration to your process.
QA Lubricants
Light to medium duty
An economical soluble oil for general machining, grinding and sawing operations. Designed for ferrous and non-ferrous materials.
A practical starting point for routine machining and mixed-material work.
Container options & pricingLight, medium & selected heavy-duty work
An economical soluble oil with a biological-control additive package to help extend sump life and a lubricity package for superior finishes and close tolerances on aluminum and other soft to medium materials. Suitable for ferrous and non-ferrous materials.
Choose when surface finish, tolerances and lubricity on softer materials are priorities.
Container options & pricingMedium to heavy duty
An economical soluble oil for medium to heavy-duty machining materials and operations. Combines an excellent biological-control additive package for longer sump life with an extreme-pressure additive for medium to hard materials.
Choose for increased cutting severity and more demanding materials.
Container options & pricingLight to medium duty · Long sump life
An advanced soluble oil designed for long sump life. Suitable for ferrous and non-ferrous materials and recommended for light to medium-duty machining.
Choose for routine to moderate machining when extended sump life is a priority.
Container options & pricingMedium to hard materials · Heavy-duty operations
An advanced soluble oil designed for medium to hard materials. Combines an advanced biological-control additive package with an extreme-pressure additive for heavy-duty operations and hard materials.
Choose for more demanding cutting conditions that require added EP performance.

QualiChem Metalworking Fluids
Economical soluble oil
For cutting and grinding of light to medium-grade metals. Non-staining to aluminum and yellow metals. Uses very-long-chain chlorinated technology and produces a milky, stable emulsion.
Recommended dilution
Machining: 4–12% · Grinding: 3–5%
Leaves a slightly oily protective film.
Container options & pricingGeneral-purpose · chlorine-free
A multi-purpose coolant for machining and grinding ferrous and non-ferrous metals. Suited to job shops working across a range of metals, including most aluminum alloys such as 6061-T6 and yellow metals.
Recommended dilution
Machining: 4–12% · Grinding: 3–5%
Semi-translucent emulsion; low foaming with a soft, non-tacky residue. Not intended for long runs of gray cast iron or grades 40 or 60 nodular iron.
Container options & pricingGeneral-purpose soluble oil with EP
A multi-metal machining and grinding coolant with a chlorinated extreme-pressure package. Non-staining to most aluminum alloys, including 6061-T6, and yellow metals; provides corrosion control on ferrous metals.
Recommended dilution
Light–moderate machining: 4–6% · Heavy machining: 7–12% · Grinding: 3–5%
Semi-translucent emulsion. Not intended for long runs of gray cast iron or grades 40 or 60 nodular iron.
Container options & pricingSpecifically for copper & brass
Designed for cutting, grinding, drawing and forming yellow metals, especially difficult-to-machine lead-free brass. Provides lubricity while inhibiting copper leaching into the fluid and yellow-metal staining.
Recommended dilution
Machining: 4–12% · Grinding: 3–5% · Drawing: 5–20%
Do not select Q-Sol Cu when parts require subsequent plating or anodizing; review Q-Sol Cu-P with QA for those processes. Not intended for long runs of gray cast iron or grades 40 or 60 nodular iron.

Typical values from the supplied QualiChem data sheets, not specification limits. The Q-Sol 286 information is from the supplied historical sheet marked 11/06; confirm current product requirements with QA.
Mixing & concentration control
Mix with room-temperature water, adding coolant concentrate to the water, never the reverse. Use premixed coolant for makeup. The Q-Sol 201 and Cu sheets recommend DI or RO water for makeup; review water quality and makeup treatment with QA for your operation.
Calibrate the refractometer before use and follow the product-specific concentration table. The raw refractometer reading is not always the actual coolant concentration. Water quality and the instrument used can affect readings.
Tables from the supplied sheets using distilled water and the listed Atago instruments. Percentages below are actual coolant concentration; the other rows are instrument readings.
