Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The one-pint bottle of coolant lasted through a full afternoon of milling and drilling without needing a refill, which surprised me. Setup took maybe ten minutes and the spray pattern on my lathe is steady, no sputtering mid-cut. Exactly what I needed for my small shop.

Adam ★★★★★

Swapped out a squeeze bottle for this on the drill press and the fine mist keeps the bit cool without soaking the workpiece. The pint of coolant included with the unit is a nice touch, and adjusting the flow to a barely-there spray took seconds.

Hannah ★★★★★

The spray pattern is adjustable so I can switch from a wide mist for sawing to a focused stream for drilling without changing anything else. Cuts down on heat and keeps the dust down way better than I expected for the price.
