Review on HDDU Rotating Woodworking Grinder with Embossed Grinding Function by Pavel Craig

They match the project I bought them for perfectly. I had to remove the wood and plaster around the hole I drilled for the bathroom vent to get out of the house. He took the right amount of material at the right pace. It was fast enough, but not so fast that I accidentally recorded too much footage. The quality and sharpness are good and are now in my drill bit set for future use.
