🔧 YUFUTOL SA5-NF Tungsten Carbide Rotary Burr Bits File for Die Grinder, Cylindrical Shape, 1/4" Shank, 1/2" Head Diameter, 1" Flute Length, Pack of 1 - Aluminum Cut Review

Probably one of the best cutters I've used for roughing material. I've used it to turn the center hubs on some old aluminum and steel landing gear wheels. Still kicking after a full set of wheels.

Excellent quality. Unfortunately, it's a lot more aggressive than I expected. Live and learn to buy. You definitely can't blame the product. Too much to clean up after cutting the chain which is why I bought it. Very sharp and unencumbered with aluminum.

This is an impressive accessory, it is well weighted and sharp. However, you charge for what you can use with CNC. But it has a hard bottom so it doesn't polish the wood well if you try to use it as an end mill. There may be some CNC applications where this will work, but they will be few and far between.

I had to remove some of the aluminum to match the existing depth of cut and it really helped. I had small pieces of aluminum flying around. It pulverized the material and dissolved like butter. I'm not saying it was easy to use, but by holding the Dewalt 20v straight grinder steady it really cut through the material. The Bulgarian needs to be held firmly and with some force, and she still managed to escape from me a couple of times. It removes non-ferrous metals in seconds. I would buy it again

I think you guys make quality bits. Check out the photos. I just contacted support hoping to fix the problem. Within 2 seconds of use the flanges exploded/sheared off and hit my goggles. I would love to return and get the same. Having used many of these styles in the past, I know better than to continue using one with a potential defect. never mind Just a replacement. Looking forward to hearing from you soon. Edit: Thanks Yufutol! Responded within 24 hours and sent me a replacement bit…
