Buying Guide

Choose the right formulation

Water-based and semisynthetic coolants (e.g., water-soluble and semisynthetic fluids) balance cooling and cleanliness, while straight oils prioritize lubrication for heavy-duty cutting

Match coolant to application

Select a fluid designed for the work: annular cutter and general metal-cutting fluids for drilling and milling, semisynthetic saw coolants for blade life and surface finish

Check compatibility and mix ratios

Confirm dilution requirements and machine compatibility—some products require specific mix ratios (such as 10:1) for optimal performance and biodegradability

Consider tool-life and surface finish benefits

Look for formulations and additives that explicitly cite tool-life extension and improved surface finish for the materials you machine

Evaluate application accessories

A coolant mister or magnetic-mounted delivery system can improve coolant targeting on CNC and milling setups when space or clamping restricts coolant flow
