Tap Magic 30004P ProTap Cutting Fluid, 4 oz. Size

Perfect

Works well

The standard. I dont know of anything else. My dad started as a machinist 60 years ago and used Tap Magic. We are still using today. Props to Amazon for selling this quality product. The size bottles are nice. You only use a small amount depending on what you are doing.

can find at a good parts store for $5/8 ... just look for free shipping . this is good stuff

Slicker than snot on a wet doorknob! Kept my project neat holes were clean and on point. Drill bit squealed a few times, but that was operator error. Otherwise worked like a champ!

This cutting oil tends to cling to the metal being worked, therefore offering better cutting action by the tool. I use it on my Drill Doctor and the Tap & Die set.

If you haven’t checked out project farm on YouTube he reviews different items and rates them. Worth your time to watch the video and see why this product came out on top.

Does work really well and keeps bits cool while cutting ribbons.

I use this all the time for taps, dies, drilling, ect. It works really well and it smells nice too. It gets 4 stars because the little red cap on the tip will sometimes pop off if you drop the bottle. They should get a more secure design.

Fluid very thin compared to the others I tried, however it kept the bits cool, actually surprised me because of the thinness of the fluid, it could of been a misguided observation of the fluid not lasting because of the thought of it being thin. Bottom line it did a great job of keeping the bits cool
