Review on 🔧 Straight Chucking Machine Reamer Milling - Enhanced Precision and Efficiency by Jimmy Jefferson

You get what you pay for. These reamers will certainly clean the hole and make the non-circular hole more concentric, but they're not very useful for precision work. I felt they were too big and some of the cutters were uneven. For general cleaning this might be fine, but I needed a 5mm hole to hold the 5mm bushing securely and the bearing didn't fit snugly after using the reamer. The bearing was a bit oversized and I was expecting a tight fit that would have to be pressed in. As I said, the bearing does not stay in place. This means that the reamer was even larger than the sleeve. Lesson learned! I bought a quality reamer from a well known brand for more than the cost of this entire set and got what I needed. If you need precision, they will NOT get the job done. This is due to the tighter tolerances on inexpensive tools. I will use them for general work that doesn't require tight tolerances. With that in mind, they are inexpensive.
