Tap Magic 20016A Aluminum Fluid with Spout Top, 16 oz, Light Yellow (Pack of 1)

Works great for when your working on finishing an 80% lower. Tried WD-40 and some other things and it took a lot longer and didn't work nearly as well. Use this especially when drilling the pilot hole for the end mill on my router and for drilling the pin holes. Have it in a little oil sprayer so I can add a few drops at a time. The drill bit seems to clear the chips easier and drill deeper with less force. Also seems to help the end mill bit run smoother. I would definitely buy it again.

My only recommendation would be to make with available is smaller container option - I only needed about 2 oz to drill 300 holes - and now have a lot left for future projects.

I used to use this stuff at my last two jobs and we liked it at both places (GM and Millbank Mfg. both of which are now history in Kokomo.) I've just got reacquainted for my home shop and am just as pleased with it as ever. I was using quart cans of Tap Magic with no major complaints but grabbed some 16 ounce small round plastic containers because I can control the flow much more accurately with them as opposed to the bigger tin cans. It's a much better "feel" type thing so I'm not wasting anywhere near as much as I used to. The acid test is that I've not broken any little taps using these containers. My big complaint with over soaking with the bigger cans is that slowly over time the excess would collect in the Bridgeport and Tormach t-nut tracks and slowly turn into a dark gooey thick mess. So I'm still happy with Tap Magic and these plastic squeeze bottles are much easier to control than the tin cans,Dave

A must have if you are doing much drilling or milling of aluminum. Does the job in providing longer life for your cutting tools.

I picked this up for drilling and tapping aluminum. I’ll admit when I tried it for the first time I didn’t think it would work very well because I thought it was pretty watery but when I used it to drill holes in some 5/8” aluminum plate it worked flawlessly. Very pleased with its performance and price!

I decided to try Tap-Magic Aluminum to discover if it was preferable to the expedient substitutes that folks often use when machining aluminum. I don't have an opinion on that, yet.My primary purpose in writing this review is to call attention of casual readers to the fact that this product listing is for twelve, 16 oz bottles! At the time of my purchase, that was buried in the fine print of the product listing. I thought I was buying one very expensive bottle of Tap-Magic! I don't mind receiving more product for my dollar, but I don't do a lot of machining (yet) and nearly fell over when I received an entire case.Also, at the time of my purchase, the product image showed the product in a steel can. The product I received was in plastic bottles with flip-up spout integral to the threaded bottle cap. I don't have a package preference at this time, but thought I'd mention the matter in case someone out there was specifically seeking the metallic containers of yore.EDIT: If vendor price spreads are any indication, at the time of this review it looks like different Amazon Marketplace sellers are offering/fulfilling different quantities of product on the same product page. I guess some of the vendors overlooked the details of the product listing, as I originally did. Hopefully someone will edit the product listing to improve clarity. In the meantime, judge carefully and choose your vendor accordingly.

Here's the deal. If you're not a pro shop, this is enough "Tap Magic for Aluminum" to last the rest of your life. I should have checked the quantity more carefully.

I have used this product before and have been very satisfied with the results. Would definitely recommend using it, whenever a cutting fluid is suggested.
