CRC Truetap HD Cutting Fluid 03400 - [Pack of 12] 16 Fl. Oz. Heavy Duty Tapping Oil and Cutting Fluid

they give all sorts of warnings not to breath this stuff in. the liquid is like a corn syrup. and from my general tests it seems to work well enough. i drill through bed rail (the thing that holds your bed up, makes great angle iron and everyone throws it away). but i was never able to make a hole without a lot of yelling. the material would get harder the longer i tried, or near the bend it always seemed to be harder.even with the cutting oil i was using it never worked.i used this stuff and i was able to cut through it without issue. i still have to try a bigger bit, i used a 1/4" but always had issues cutting it. used to destroy all by bits.you will want to put this into a smaller bottle though, this one is clumsy though it does have a small release hole.its a bit pricey for what it is, but got a great review on you tube when he experimented with this and other things, even bacon grease, it was a weird video. but you get a lot, so i figure this will last me the rest of my life.

Nice cutting/tapping oil at a great price point. It's thick, it sticks, it's slippery enough but not too slippery. Basically, what you'd expect in a cutting/tapping oil. I don't have any complaints about the oil, but the bottle it comes in sucks. Well, the bottle is okay but the spout is the worst. It's the square type that leaks when you look at it. If it ends up on its side, you'll have an oil spill on the bench. The spout itself is too short and can't reach anything, definitely not anything and not be in your way. Forget about using it at the drill press. After using it, oil manages to sit in the space where the tip nests into the top and makes a mess. In any case, I suppose most readers will have an idea of the spout I'm describing. It sucks, and especially for an oil. Be prepared to have a different bottle for dispensing. Bottom line, the oil is a 5 star, the bottle is an unenthusiastic 2 star.FWIW, I've found that old rooster sauce bottles work well. Minus the writing they are clear, the spout is more of a cone, the tip can actually reach into spots without blocking your vision, and FAR less mess because the tip doesn't fold into a valley, but just goes up/down.

THe cutting oil is a great thickness, it gets to where it needs to go but doesn't run off unless you over do it. The bottle lasts a lot longer than I expected.

This oil has worked real well for me drilling through metal. You can definitely tell that it works when drilling. A complaint I have about it is when trying to put oil on the bit or in the hole it is a little hard to not waste some every time and when you stay the bottle back up you have oil running down the sides making it very slippery to hang onto. I might try to put it in a spray bottle. I wish they offered a squirt model instead of just a pour bottle.

Cutting fluid has changed my mechanical life, I no longer burn through bits and I am able to cut or drill through projects 10x faster than before. I found out about cutting fluid and decided on this one, it did not disappoint. It’s viscous nature allows it to stay right where I put it. I use it on the cutting device (bit or blade) as well as on the project itself. Drilling 1/2” holes in the frame of a truck was far more efficient than I thought possible and the bit wasn’t completely ruined after.

I may have lied on the easy to clean with 5 stars, but I love this stuff. It sticks to the part even at higher RPM. My tools stay sharper/longer. I’m not smelling it burn like I do with some of the bigger names in the tapping and magic world. Use this, you’ll AT LEAST, will really like it.*edit One bit of warning! If not immediately cleaned from vice or ways ...it will STAIN I won't take off stars for this as it works very well, but a warning on the bottle would have been helpful. You have been warned...now be safe!

This is my favorite cutting fluid of all time. I keep some on my bench in an oil can and the rest in the original container. I use it for drilling, tapping, etc. Not much more can be said, it does what it's designed to do and it does it very very well. It usually lasts me a long time but whenever I run out, I always buy another. I've tried all of the others, and I always come back to Truetap.

Started using this oil for drilling mild steel and use it for every cut now. It's kind of thick and hard to pump out of an oiler if your shop is cold. On the plus side you can just put it in the flutes and there's almost no waste, by the time it gets to the tip you are drilling and it "feeds" into the cut. Seemed like tapping requires a lot more juice, not sure if a more fluid oil would be better, but I would definitely buy again, if only for drilling.
