Tap Magic20016A Aluminum Fluid with Spout Top, 16 oz, Light Yellow (Pack of 1)

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.

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.

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 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

I bought this thinking it would be better due to it's name being specific to aluminum. However the slightly thicker Tapmatic #1 Gold works better when cutting aluminum with hobby circular metal saw blades.UPDATE March 12, 2020 - Tried this for drilling aluminum and works great so now use this as my first choice for drilling. It's weird but the Tapmatic still is better for cutting aluminum with circular saw blades.

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 been using this for about 15yr. Use most working in lathe and milling.

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!
