Review on 🔧 YUFUTOL 5 Pcs Carbide Burrs Set for Aluminum - Extended 4.4" Long Reach Carbide Rotary Burr Files Set with 1/4 Inch Shank for Die Grinder Drill, Metal Carving, Polishing, Engraving, and Drilling by Chris Wagner

Ordered this set and saved money. I used my drill press and machined a 3/4 piece of sheet metal and after 5 minutes of use? The bat completely broke in half, the fragments scattered in all directions. Glad I wore glasses. Of course I bought them for an upcoming project and didn't try them on the first delivery. I've owned them for 2 weeks and used them once and they are useless. Now I can't get my money back because the window (which was brief) was closed and you can't find anyone to help replace it. So disappointment and utter robbery!
