44mm-58mm 360 Degree Table Bench Clamp Vise Electric Drill Rack Support Electric Drill Stand Holder Multifunctional Bracket For Electric Drill, Grinder,Rotary Tool,Hobby and Jewelry Ma(B Type：44-58mm)

My initial impression was very good, however I decided to move it a little. I was going to loosen it, slid it over & retighten it.The knurled knob is a kind of rubbery plastic. When I attempted to loosen it the knob just stripped out. It turned into a major project to dismantle the whole thing and re-glue. I hope I don't need to try it again. I don't think it will survive!Based on the description I wasn't sure if I could use this for my dremel, the internal dimension appeared to be too small. Turns out it fits perfectly. See photo I have a flex extension but also wanted to use this as a solid mount for a grinding wheel attachment.I'm very happy with this

This Chinese product came rough and I had to hand file the ball joint to get rid of casting marks. There was also flashing that I had to grind away. Everything looks like it was made in a hobbyist's shop - cheap and slapped together. The clamp is especially egregious.I'm actually trying to figure out if I can use any of this or just throw it away.

It works and it's cheap. For the price you can't beat this. Not the highest quality metal, or machining and finishing of the parts, but more than good enough for it to stand up to reasonable expectations of how it can be used.

Glad I got the 44mm-58mm model because it fits WEN 23114 rotary tool perfectly! Seems solid enough for good use. Used double faced tape to keep rubber bumpers attached.

Versatile little device for my rotary tool and drill.

Product work as was advertise and is in excellent working condition.I am happy with this product and the price I paid for it.
