Review on 💎 Diamond-Coated Grinder: Precise Shaping & Carving with Threaded Precision by Patrick Reid

These fit perfectly with my Bosch 4 1/2" angle grinder with the large center hole. However, they don't fit my Craftsman 4" Sander as it has a smaller bore. They have lots of razor sharp teeth. I like the dome shape which allows for very precise shaping of the wood when used to carve the edge of the belly Guitar body.If you have a variable speed grinder this is even more effective but a regular light touch grinder will do the job.You can fine tune it with hand files as you get closer to the edge,especially if you are aiming for flatter surfaces.It will be a welcome addition to your arsenal and fill a unique need in woodworking.
