What Customers Are Saying

Customers overwhelmingly praise this cutting lubricant for exceptional performance on tough metals like stainless steel and cast iron. The thick, paste-like consistency stays precisely where applied without dripping, dramatically reducing friction and heat while delivering faster, cleaner cuts. Reviewers consistently report extended tool life, with bits staying sharper longer and suffering less wear. The water-based formula is easy to clean up, leaves no greasy residue, and produces minimal odor or smoke compared to traditional cutting oils. A few users mention preferring a smaller bottle size, but overall satisfaction is near-universal across DIY and professional applications.

Cool Cutting Blu Goo

Would Recommend

This stuff works as advertised. It’s got a great viscosity that stays where you put it. Blade didn’t overheat when I was cutting the angle iron. Everything I’ve used it on has stayed nice and cool, so the blades and drillbits don’t overheat stuff works pretty amazing. It is a little messy though, but overall well worth the mess.

Super product and no friction!

Would Recommend

Used this recently to drill some holes in a steel pipe for a Martin bird house. It provided great lubrication and no additional heat to the project. After drilling a few holes, I realized my drill bit was just as sharp as when I started. I detected no friction whatsoever. I look forward to using it again.

Makes drilling much easier

Would Recommend

First time using a product like this. Wish I would have known about Blue Goo sooner. Very easy to use. Simple apply a little bit to your drill bit, saw blade, or surface you're working on. I was drilling though some metal for a DIY project. The Blue Goo made the drilling faster and the holes were a much cleaner cut. I also liked that it cleaned up very easy without leaving any greasy residue.

Excellent product, highly recommend for everyone.

Would Recommend

Usually use a spray on lubricant this was something different. Being water based and the blue, it adheres to any object really well. We used it on heavy steel. It did a remarkable job. No smoke, no odors.

Keep your bits cool

Would Recommend

I used it on my ladder rack on my trailer to drill through the steel. The liquid kept my drill bit cooler for a clean hole. It was easy to use and was not to messy. I also use it on 90 degree brackets to attach to my ladder rack. It made it quick and easy.

Water Based and Non-Toxic Cutting Fluid

Would Recommend

I'm a tool maker in addition to operating a home improvement, repair, and remodel business. This product performed well when I tested it on aluminum. Aluminum has a tendency to bind to cutting tools and I found it did not try to do so when I was drilling. As you can see, the vice isn't being held down by anything and didn't try rotate. The drill was left very clean afterwards. I like how it is water soluble so parts I need to drill can be cleaned up without a oily film afterwards. I haven't trie...

The blue goo

Would Recommend

Im only giving it a 4 star because my husband's not completely happy about it. His large scissors had gotten a little tough to use so i thought it would be great to test this Mach-blue goo on them. He feels that its more of a lotion consistency and more dirt and grime will be attracted to it which in return will cause more issues with getting stuck.

The secret is in the Goo!

Would Recommend

I am very happy with the performance of this product. I've been using cutting oils for years but this product really is a "goo" as the title suggests. Instead of having to constantly run oils into the cut, this stuff hangs in there which is convenient and very handy when you don't have three hands to work a cutting tool.

Great product for cutting metal

Would Recommend

This product is great! I needed to use it to cut some chain link for my RV and it worked as advertised. It’s a nice thick goo unlike some of the other lubricants out there that just run right off.

Easy to Use

Would Recommend

Stays in place and cleans up nicely. Doesn’t leave smudges or residue after use and doesn’t require as much as cutting oil. Also no noticeable smell like other cutting oils.

This product worked very well in keeping my drill bits sharp. I had found that they were getting dull after a few uses but now remain sharp with the use of this product.

Blue Goo

Would Recommend

I was weary of this stuff at first, I mean how many times can you re-invent the wheel? However I was pleasantly surprised bit it. Not only does it work great, for cutting lube, like it advertises it sticks to bits or your surface - is easy to clean up - and to top it off it actually has a nice smell to it too!

Professional Grade!

Would Recommend

This product is professional grade. I took it to our machine shop and used it to drill and tap one side of one of our products. It worked as well as other products purchased for this.

Mach-Blue Goo Cutting Tool Liquid Test 02/2023

Mach-Blue Goo Cutting Tool Liquid arrived a couple weeks ago but I just got a projet that I could use it on! Hard metal plate that the drill bit seems to want to slip on! This Item seems to do the trick very well! Also kept my drill bit from getting way to hot and did not slip when I started the drilling! No bad fumes or smoke from the drilling and seemed to speed up the cutting!

Longer Blade Life

Would Recommend

I was going through cutting blades like crazy and saw this stuff to use. I tried it, and first and foremost, a little goes a long way. I'm using my current blade 5 times longer than I normally would and there's plenty of life left in it. There's a lot of other purposes for it aside from cutting, like sharpening knives and lubricating bolts and such. Overall, it was a solid purchase and should last a long time.

Well made

Would Recommend

Nice thick cutting tool lubricant. Not thin, oily or watery. Depending on your project, it can be very helpful and would certainly come in hand as cutting tool lubricant.

Smooth cut, no jamming up

Would Recommend

Test cut on a piece of conduit shown in pics was easy to cut the pipe. It was smoother and didn't jam up like in the past. I look fwd to using it again. It left a clean cut too. No jagged edges

Less mess

Would Recommend

Very helpful. I typically use spray lube to punch holes in thick steel. I like that this paste is thick enough to stay in place without splattering but does not run all over my project and wirk surface. A little dab goes a long way and stays on the tip of the bit.
