An alternative to nearly dry machining, apply these coolants to tools before milling and machining to reduce heat with minimal cleanup. They’re often used with shallow drilling, reaming, and tapping, as well as on saw blades. Remove from tools and work surfaces with alcohol, methyl ethyl ketone, or a parts washer. They are chlorine free, for use where chlorine waste disposal is a concern, and sulfur free. Use at full strength.
