Ready-to-use fluid or coolant concentrate?

Ready-to-use cutting and tapping fluids go straight on the tool for drilling, tapping and mag drill work. Water-mix coolant concentrates are diluted for machine tool sumps and saws; the dilution ratio sets lubricity, cooling and rust protection. Cutting sticks and paste stay put on vertical and overhead work and on band saw blades.

FAQ

Do I need a different cutting fluid for stainless steel?
Stainless work-hardens and runs hot, so a fluid formulated for stainless or a heavy-duty tapping fluid lasts longer and gives better threads than a general-purpose oil.

What is a coolant concentrate and how is it mixed?
A concentrate is mixed with water in the machine sump, typically at 5 to 10 percent for general machining and grinding. Check the mix with a refractometer and top up with premix, not straight water.

Why would I need a coolant system cleaner?
Over time sumps grow bacteria and fungus that cause odor, foaming and rust. A system cleaner is added before draining so the machine is clean when fresh coolant goes in.
