🛠️ YUFUTOL 5pcs Carbide Burrs for Aluminum - Aluma Cut Rotary Burr Set 1/4" Shank: Die Grinder Drill, Metal Carving, Polishing, Engraving, Drilling Review

I use them to clean a weld on cast aluminum and they work great. Highly recommended if you are interested in welding or aluminum work.

Excellent value for money. The cutter heads have been precisely centered so there is no uneven wobble that you get with most cheaper cutters. I love her! The first job I did, they paid themselves.

The bits looked good when they arrived but as mentioned they were all lying around in plastic boxes and hitting each other. Haven't found any chips around the edges yet, but the boxes are in dire need of foam or something to safely separate the pieces. The seller should take more care when shipping.

This is a good product that allows you to quickly grind and shape aluminum. When I received my product the stop inside the case was not adjusted properly and the bits rattled during shipping. Several router bits had broken off and at that price I sent them back for replacement. I will update my rating after the change.

I've just bought a Dewalt 20v Cutoff Tool and needed deburring tips. At work I mostly deal with aluminum, but sometimes also with steel. This set had a large assortment and a practical case.

Deburring bits are often used and overused, so replacement cost was a major factor in their selection. I've used them several times so I'm satisfied.

I can't lie I didn't expect them to be this good. For $60 I can only buy 1 drill bit at my local hardware store. With this kit I got 5 ridges. I have already made 2 ports on the cylinder heads and they are still in perfect condition. If you're buying an aluminum port, I highly recommend fitting a stopper to your air gun (unless you're using an electric grinder). If you set it to medium speed and move back and forth smoothly these bits will last a long time and won't clog with aluminum as…

Wow! I ordered these for my Makita as the set I used on my first head was annoying and VERY ineffective. I carried my 383,500hp, Target, Aluminum, Knock Heads from ebay and finished the first one - I ordered them because I was too lazy to clean them and thought I'd do it another day - BOOM! These bits chewed aluminum like butter! Nice chips flying all over the place, NO irritation, slick as hell - can't believe two sets of almost the same price can be so VERY different - I'm so used to it that…
