Rapid Tap Heavy Duty Cutting Fluid 4 Ounce

Good ol trusty

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

Good Product

works great

Excellent. Kept everything cool n lubed with aluminum. It does what its intended to do.

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

Great product

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

It does exactly what its supposed to do. Great product!

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.
