Would Not Recommend

I bought this with the purpose of removing grout from the edges of tiles. It worked okay but was not the tool for the job. If I had bought it for small woodworking or metal projects it would have been perfect. The tool itself was easy to handles my only complaint was the attachment screw. It was nearly impossible for me to attach the blade because it was so small

EZ twist integrated wrench /nose cap melted

Would Not Recommend

It melted the EZ twist integrated wrench / nose cap and the thread on the body the first time I tried grinding with it. It's obviously not fit to be used for grinding.
