Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Great for when you are tapping threads in hard steel. I have had taps bread in the past and this seemed to make it less likely to happen again,

Made drilling 1 holes in 3/16 steel plate cut smooth as butter.

If you are drilling holes in any thickness of steel you need this product. I dont know what is in this fluid,but after you use it once you will not believe how great it works. You should center punch your work. Then drill a small cup. Add the fluid and start drilling. When the fluid burns off you need to add more. Continue this process till the hole is drilled. This fluid is truly an outstanding product. I got two extra bottles of it just to have in my tool box.......outstanding performance....... Kris

Been using tap magic for several years, always works, keeps taps and dies sharper longer.

The smoke the come out is really dangerous! I almost went to the hospital after using it

Longevity

Smells a lot like the thick black sulphur containing oil we years ago threading pipe... except its thinner and almost clear. I have only used it once but it seems to work very well.
