Metalworking Fluids

Selecting metalworking fluids

Identify the machining operation, workpiece material and fluid system before choosing a product family. Compare water-miscible fluids and neat oils using product-specific technical guidance.

For fluids mixed with water, confirm water quality, the recommended working concentration and the product’s refractometer factor. Check package size and the relevant technical and safety documents. Cleaning products and coolant equipment belong in separate categories.

Fluid-system components have product-specific requirements. Confirm the required fluid, active component and working concentration with technical support; products are not interchangeable.

Prepare a fluid-program comparison

• Identify the machine, operation and workpiece materials, together with any machine-maker fluid requirements.
• Record the current fluid and the concern prompting review; include available concentration and maintenance records.
• For water-miscible systems, provide water-quality information and identify the supplier’s working-concentration and measurement guidance.
• For a proposed change, request product-specific conversion and maintenance instructions. Treat finished fluids, separate active components and maintenance treatments as distinct selections.

Questions before you select

How do I choose between a water-miscible fluid and neat oil?

Start with the machining process, workpiece material, machine requirements and fluid-system design. Compare the specific products’ application guidance rather than selecting on family name alone.

Can I use one concentration target for every product?

No. Use the selected fluid’s technical guidance for the operation and the product-specific measurement method. Confirm water quality and any separate component requirements where applicable.

Are HYCUT active components interchangeable with finished fluids?

Do not assume interchangeability. Confirm the exact component, required fluid system and working concentration with technical support before changing a fluid program.
