Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz - Pack of 2

Works very well for drilling and tapping any metal. Expensive but a little goes a long way. Cuts bit chatter a lot. Helps make nice tapped threads.

Work very well, small taps ie: such as 8-32, 10-32 in steel, you need something better the petroleum base lube. OIL ! This stuff is what you need for tapping (Threads) in Steel, and high Alloy materials!

This product helps in the ease of threading the hole that you will be taping. Also it helps to prevent the tap from getting bound up while threading. Great product,this is a must have product in the machining process.

This cutting fluid is fantastic! It works great for threading, drilling, and tapping. The lubrication reduces friction and keeps tools running smoothly. I noticed a significant improvement in both speed and accuracy while machining. Highly recommend it to anyone doing metalworking or repairs!

If you do any bolt extraction, this is a must have oil to keep your drill bit cool and sharp longer. I used to squirt random oil that I have on hand, but this is definitely very effective.

Best cutting fluid. Doesn’t spray all over the place when spinning the tap bit, like lesser quality cutting fluids. A+++

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.

Works great will buy again

Quality product

para taladrar cosas de metal es muy util, para concreto o materiales mas blandos realmente como que es lo mismo

Elexcelent for drilling holes in thick steel plate

I had broken tens drill bits before I got this. After I had it, any drill bits won’t be broken any more. It’s my magic portion. It saved me.

me gusto mucho como el fluido ayuda a perforar el metal , en brocas que les falla el filo se nota como ayuda al corte , alarga la vida útil de tus brocas con tan solo una gotita por corte
