Review on HDDU Rotating Woodworking Grinder with Embossed Grinding Function by Timothy Barnes

I bought this for fine woodworking. They should speed up carving things I usually do with a chisel or chisel. So far they're doing a decent job. They leave the job a little rough, but that's to be expected. Maybe a little better at higher revs. The bits are rated for 20,000 and my drill is hitting the less than 3,000 limit. Closer to 2K when using a flexible head. If you buy them for the same or a similar purpose, please keep this in mind. Plan for additional material to work on. Like many tools, they will save you time, but they won't do all the work. Again, higher speeds can result in cleaner operation. If I've had any complaints, it's just the need to use a 1/4" drill chuck. My drill bit has a flex head, so that wasn't a problem for me. However, I would recommend them to anyone looking to do a really good job uses.
