Tap Magic 30004P ProTap Cutting Fluid, 4 oz. Size

Seems to rust steel if not cleaned off very well.

I use Tap magic to prevent a stripped out bolt from breaking off. Just put a few drops on the bolt, screw, or nut at the first sign of resistance. Wait a minute or two and then work the screw back and forth and then slowly remove. Works like magic, I have been using for years!

Works like advertised

man, I snap tiny taps all the time. Because they are tiny almost no force can be applied to them. I have used cutting oils before, but this is the FIRST product whereby I apply it and the tapping gets done quickly and without incident. I bought it after having to drill and tap 303 stainless rod with M3x0.5 threads. Once that alloy has been drilled with a drill press it has already started to work harden, so the tiny tap is a victim before you even start. I had to produce about twenty end-drilled and tapped 6mm rods one afternoon and I snapped off eight taps. I have excellent thread-cutting skills and have been doing this for several decades now. This 303 alloy was new to me and I was doing it wrong, somehow, I guess. I had to waste a lot of linear rod by cutting off the ends because the dang tap was stuck in there. I had been considering your product for some time and that day finally pushed me to order a small bottle. I use it just about every day, to include a lot of this same size/pitch (M3x0.5), and have not snapped a tap or drill bit since. Not a single one in thousands of operations. It is sticky and you have to clean up after you use it, but it smells nice. What is that? Key Lime scent? It smells like pie, man. Nice. I am now a loyal customer. Great product. Highly recommended!

Second time to purchase. This is good cutting oil. Only problem is keeping up with the cap, which gets lost easily in a shop. This new one arrived without a cap, shame on the distributor. Not worth the trouble to send it back.

makes drilling and tapping easy on the tool, the work, and me!

The standard. I dont know of anything else. My dad started as a machinist 60 years ago and used Tap Magic. We are still using today. Props to Amazon for selling this quality product. The size bottles are nice. You only use a small amount depending on what you are doing.

I used in steel, with cobalt drill tips...excellent combination.

Works good and is a good value.

The cap needs to be threaded on so it can be pressure sealed. Cause when i carry it in my bag it spilled everywhere. Other than the cap being a poor design. Everything is good
