Choosing the right coolant for CNC cutting machines is a balancing act between part protection, tool life, and shop-floor stability. If you've been looking for a synthetic option for multi-metal work, the Clisyntec Premium Synthetic Machining Coolant in the 1-gallon size gives you a specific set of features to weigh before you commit.
Quick verdict
The Clisyntec Premium Synthetic Machining Coolant, priced at USD 90.68, is a liquid synthetic coolant designed for CNC machining, sawing, cutting, drilling, milling, and grinding. It's a true oil-synthetic solution that emphasizes corrosion protection, stability, and foam control. For a shop that wants a formula suited to a range of metalworking operations, this is a practical candidate - provided you're comfortable with the 1-gallon packaging and mixing it yourself.
Who it suits
This coolant is aimed at machine shops and fabricators running CNC equipment, saws, and grinding operations. Because it's a multi-metal formula, it's a reasonable fit if you work with different materials and want one coolant across several machines. The synthetic construction also makes it suitable for operations where you need a cleaner, less oily workpiece finish.
What stands out
The 1-gallon container holds 128 fluid ounces, which is a compact starting point for smaller shops or for testing a coolant before committing to a larger volume. Mixing is straightforward: use 18 ounces of coolant per gallon of water, or one gallon of coolant to eight gallons of water. Refractometer readings provide clear targets - 4.0 for machining and grinding, with a range of 3.0 to 5.0, and 6.0 for sawing, with a range of 5.0 to 7.0. That level of specificity means you can dial in the mix without guessing.
The formula also includes corrosion protection and foam control as built-in benefits, which are useful for keeping both the machine and the workpiece in good shape during longer cuts. The product guidance recommends cleaning the system before adding new coolant, a sensible step when switching from another fluid.
Meaningful trade-offs
At USD 90.68, the price reflects a single 1-gallon pail. You'll need your own water and a refractometer to hit the recommended concentrations. Because this is a synthetic coolant, it may behave differently from the semi-synthetic or soluble oils you're used to. The product title points to a 'true oil-synthetic solution,' but the exact feel and residue characteristics aren't spelled out, so you'll want to test it on your own machines before running production parts.
Bottom line
The Clisyntec Premium Synthetic Machining Coolant is a solid choice if you want a synthetic coolant with clear mixing targets for CNC machining, grinding, and sawing. The 1-gallon size and price point make it best for shops that want to evaluate performance before committing to a larger volume. If you value corrosion protection, foam control, and stability, this is a product worth putting on your shortlist.

A concrete reason to choose it: the precise refractometer mixing targets make it easy to match concentration to your machining or sawing operation. A limitation: the 128-fluid-ounce pail means you're mixing concentrate yourself, which requires separate measuring and a refractometer to keep the ratio on target.
