Rapid Tap Heavy Duty Cutting Fluid 4 Ounce

I used to use plain 3-in-1 type oil when drilling thick steel, but Im now sold on this stuff. Bit actually seems to cut better, bit stays reasonably cool, and smokes a lot less. Nothing will save your bit, though if you drill too fast and too hot, not even this stuff.

This stuff does exactly what its supposed to do: It makes it much easier to drill nice clean holes and tap perfect threads.

Makes drilling and tapping alot easier..

I didnt expect that it will be so easy to tap a thread with that liquids help. It literally surprised me! And I ordered more to have it everywhere - at my work, my garage and my workshop.

works great

It seems to work but for the money I guess I expected something wonderful. I dont think it works better than any other oil.

Was looking for a good cutting oil and I found it

Good ol trusty

good

Im glad to see this product still on the market after these many decades!
