Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Works better than the others

I used it on my turning lath and found it cut better then any oil I used before. I would use it a lot more if could buy it by the qt. or gallon but the price would have to be a lot less for larger amounts.

This stuff is essential for keeping bits sharp when cutting and drilling steel.

Makes drilling easy and quick. Only need a tiny amount of it, too. Highly recommend.

I used this oil to repair the threads on the muzzle of my AK-47 variant & it worked well helped me complete my task

Bought this for use with some titanium step drill bits, based on other reviews. Works very well.

Only used this for drilling and tapping aluminum alloy, but it works well for that application. Less heat from friction, saves wear and tear on drill bit coatings and reduces the odds of breaking a tap. Worth using.

Its a little runny , but that works in favor to clean out debris. I use it on hardened fastners and it allows a complete revolution before backing off to clear tap cutting threads. I will buy it again

this made threading hard steel not to hard

Works good.
