Forney20858 Cutting Fluid, Industrial Pro Tap Magic, 16-Ounces

Had to cut a hole is a stainless steel sink top I installed and this work out amazingly. Must be applied steadily as the metal heats up fast when doing this type of project. Very satisfied.

metal working , very good

para taladrar cosas de metal es muy util, para concreto o materiales mas blandos realmente como que es lo mismo

Used it to cut holes in thick metal on the drill press. Worked surprisingly well and with little effort. Combination of low speed and firm pressure made drilling easy.

I guess it works ok for what it's supposed to do, I haven't busted any more taps than usual anyway. But if it smokes, it STINKS like cat urine. Not the fresh stuff either, like the cat that peed on the carpet in the corner of the spare room and you didn't find it for a month kind of stink. And it sticks with you for the rest of the day too, the smell clings to your clothes for ages.That much I could forgive, I stink pretty good all on my own sometimes anyway. But the deal breaker for me is that it leaves this awful corrosive residue on everything it touches. I thought my new Kurt mill vise had begun to rust, but it was just this nasty stuff gluing it up. It took brake cleaner and a good amount of elbow grease to get it off. The final straw was when it gummed up my favorite little Goldenrod oil can so bad I had to throw it out. I don't know what I'll do with the rest of this junk now, I don't dare tip it into the waste oil burner, it'll stink out the whole neighborhood!It also gels up into a solid if it gets cold, in case you were wondering. So yeah, stay away from this stuff. Unless you want 3/4 of a gallon for free, then come see me!
