### ⭐⭐⭐⭐⭐ WORTH BUYING
*by M***G on June 1, 2021*

I needed to chew through some 5/8" plate to correct mismatched holes, local carbide burrs were at least $20- apiece. This set fixed my issue, the burr I used [with a Ryobi 18v drill] seems undamaged and ready to go again and I got the entire set-delivered fast- with various shapes and sizes for only a few bucks more than a single one locally!
