Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Drilling in tempered steel? You cant get the job done without a good cutting oil, and this stuff really does the job. And its a lot cheaper than sharpening or replacing your cobalt drill bits, too.

I still haven’t figured out what the difference is between this product and the one that looks like it’s the same bottle but a different price and different part number, the bottle I’m reviewing says “Tap Magic EP-Xtra Forney 20857”. Every application I had planned for it was into a vertical surface, not flat and horizontal, so after reading some reviews saying this stuff is thin like water had me concerned it wasn’t going to work for how I needed to use it. It’s certainly not thick like gear oil consistency like other tap fluids I’ve used, it’s not as thick as motor oil, but it is a little thicker than water. I put some on my drill tip and some on the vertical surface I intended to drill and most of it did run down and off, but some also did stick and it worked amazing. I needed to drill several holes into a very hard frame on my one ton truck. The first hole I attempted was with just any old bit I had on hand, barely scratched the surface, 100 years of drilling and I still wouldn’t have gotten a hole. Second attempt was with the best bit my local hardware store had, I tried wax, motor oil, WD40, I did get a hole in it but it took a lot of effort, so much so that I gave up on my task after just one hole to see if I could find an even better bit on Amazon. What I found was this stuff and I remember seeing it years ago in tool and die shops I’d been in so I ordered it. The word “Magic” in the name is more than just a marketing gimmick, it’s mind blowing what a difference just a little of this stuff made, night and day. If I was a drill bit manufacturer I’d include some of this stuff with every bit I sold, people would think it was my drill bits that were so amazing and would have no idea it was actually this Magic Tap fluid. I completed all my holes with little effort and just one bit.

good

Works better than the others

Worked Great

I had to drill a hole thru an impact socket, and I bought this oil to protect a new cobalt bit. I got the hole drilled and did not damage the bit and drilled it faster than with a HSS bit I tried before.

Does what it is meant to do. Great for tapping out anything you want.

A must have for a smooth tap.

great for tapping and drilling in steel

Its taping oil, not perfume, it smells terrible but it works fantastically. As others have said it is a skin irritant but it says so on the bottle, I wore gloves when I used it but still had contact and didnt experience any issues.
