Cutting Oil, Cutting Fluid 8-OZ, Made in The USA | Cutting Oil for Drilling, Tapping, Milling | Professional Grade Fluid - Safe on Metal & Glass by Evo Dyne

Good stuff. Works great. Maybe I can get all of my chisels nice and sharp.

I used this the other day on a 3/4 bit & was surprised at how little I actually had to use to make the bit work better. I need to put this in a squirt bottle or pump oil can. You can't get the bottle near the bit. It is pricey, but it does work very well.

Easy to use dispenser

Works well...Needs a better / different spout for applying oil where you need it.

Good product, used to drill through 3 inch stainless steel. Used small amounts kept the drill bit from getting to hot.

Excelente cumple con todas sus especificaciones

Does not leave too much of a mess, like a lot if other fluids.

I don't know. Seems like straight dish detergent to me, but can't say for sure. Oil should leave a residue even if very light oil. There's no residue at all. If needed for lapidary work, and mixed with water, it will suds up tremendously. It wasn't really designed for lapidary work, but if it was an oil, I feel like there should be some slight residue at least. It does seem to be helping others so it might just be it's not working for my needs. I felt it was worth a try, but I really need something that is like a light oil.
