Boelube 70307-L-002- Pack of 2 pcs - Multi-Use Medium Paste High Performance Lubricant Blue 4 OZ Jar

Excellent product for drilling stainless steel and other hard metals

If you are working with aluminum you need to get 1 or 2 small tubs of this stuff! It's miracle butter in a jar!! I've tried WD-40, tried PB Baster, and I've got 2 burrs I now have to soak in muriatic acid to get the globs of galled aluminum out of. This stuff, all you have to do is roll your burr in it to start with, about every 15-25 minutes give it another quick roll and I've never had anything stick to my burrs since then. Even when working on cast iron (with appropriate burrs) it does a really great job and will help your burrs cut thru cast a lot better, faster, and cooler! I've yet to use it on drill bits for metal, but I can say for die grinding, save yourself a lot of time, aggravation, and burrs and get some of this stuff and give it a go!

If you are not an aviation mechanic, there is no way you’ll know what a great lubricant/cutting oil/drilling/tapping oil this is.

This is great stuff for drill bits, taps etc. Highly recommend it!

Never found anything that can match this product for drilling in any type of metal. 👍👍

works perfect as always

Beware of the stated contents weight. What you will receive is not 4 oz of lubricant drill paste. The gross (not net) weight of what I received weighed 3.9 oz. Now subtract the weight of the plastic bottle, top and seal. The net weight is about 3 oz, not the 4 oz one would assume you are paying for. Wonder what Boeing Inc. would say about the use of their name here? I wrote Boelube and did not receive a reply. I also wrote the seller. What a disappointment. I bought 2 of these assuming "4 oz" means that is the net weight of the contents. Silly me, after decades of engineering, paying attention to labels and measurements, what do I know? This review should focus on the quality of the product, but instead, it is the advertised weight that disappoints me most.

Well it's boelube it's as good as always it makes drilling and tapping a breeze and I feel it helps extends tap life I usually put my tap in a drill and without this it's a little sketchy I love the stuff. Would have given 5 stars but it shipped USPS other than that if you tap or drill metals and have not used this I highly recommend giving it a try
