Coolants

CNC coolant and water-soluble cutting fluid, stocked in Canada. Semi-synthetic, fully synthetic and vegetable-based, in pails, drums and totes. Prices and stock on every product page, order without asking for a quote.

What you buy is concentrate. What runs in the machine is the mix. A 5-gallon pail makes roughly 60 gallons of working fluid at 8%, so the number on the invoice is not the number that matters — concentration is.

Each product page lists its refractometer factor, the material groups it suits and whether it holds up under high-pressure coolant. Those three answer most of the choice.

CNC Coolant and Water-Soluble Cutting Fluid

CNC coolant — also called cutting coolant, cutting fluid or soluble oil — is a concentrate mixed with water and run through the machine to cool the cut, lubricate the contact between tool and workpiece, and flush chips out of the way. Shops use all four words, and in a CNC machine they almost always mean the same thing: a water-soluble fluid, not a neat oil.

This category covers water-soluble products only — what catalogues variously list as water soluble cutting oils, soluble cutting oils or plain soluble oil. If the job needs undiluted oil instead — threading, broaching, deep-hole work — that is cutting oils.

You are buying concentrate, not coolant

This is the part that changes how the price looks.

Nothing in this category goes into the machine as supplied. It is concentrate, and it gets diluted. At a typical 8% mix, a 5-gallon pail makes about 60 gallons of working fluid; a 55-gallon drum makes close to 700. Run the same pail at 6% and it stretches to 80 gallons, at 10% it drops to 50.

Two things follow. First, comparing pail prices between products tells you very little until you know the concentration each one runs at. Second, the cost of a sump is set by the mix you hold, not by what you paid at the counter — which is why concentration drift is expensive in both directions.

The coolant calculator works out what to add for a new fill or a top-up. Sizes here are 5-gallon pails, 55-gallon drums and 270-gallon totes.

Reading the sump: the refractometer factor

A refractometer does not read concentration. It reads Brix, and you multiply.

Every coolant has a refractometer factor — ours run between 1.2 and 1.6, and it is listed on each product page. Actual concentration is the reading multiplied by that factor. A reading of 4.0 on a fluid with a factor of 1.5 is 6% in the sump. The same 4.0 on a factor of 1.2 is 4.8% — weak enough to start losing lubricity and grow bacteria.

Which is where shops get caught. The refractometer target gets written on a card taped to the machine years ago, the shop later switches to a different coolant, and nobody changes the card. The reading looks right and the sump is running one or two points off. If you change product, change the target number with it.

The filter panel on this page lets you sort by refractometer factor, which is worth using if you would rather keep a mixed shop reading against one number.

Choosing the best coolant for CNC machines

The practical difference between formulations is how much mineral oil is in the concentrate, which is listed on every product page.

Semi-synthetic

Mineral oil at roughly 20-30%, blended with synthetic additives. The general answer for a shop that cuts several materials and does not want to run two sumps. Enough lubricity for steel, clean enough to keep the machine tidy. is our most-ordered coolant and is the one to take if you would rather not think about it.
