Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Works great used a lot of years.

The Original Tap Magic - a must have for drilling steel and other hard metals.

I cut off a little too much off the tip and it just runs out. Should have just used a straight pin would have been plenty. Seems to work well.

makes the drill bit cut deep

I always keep some on hand in the cabinet over my work bench..

Perfect for small tooling/machining jobs. Not to tacky, allowing metal chips to be easily cleared, and keeps cutting bits cool.

Worked great drilling out and removing sheared-off bolts.

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.

My Customer wanted to install an air switch for his Garbage Disposal. This oil will prolong the life of my drill bit.

I dont have a machine shop, but do drill metal quite often by hand and with a drill press. Had a can of some very old stuff that worked, but this is better. My only complaint is that it is like water rather than the easier to use thick oil consistency of the old brand. Sort of pours of the spout and I often use more than what is needed. I think a longer spout would help to get a little into a partially drilled hole. Maybe I will look into some sort of oiler with a long flexible spout and a precision squirter thing. Still, it makes drilling easier and saves so many bit resharpenings. It is recommended.
