It’s time for another Cool Tools review. This week I’m going to show you an angle grinder holder made by Klutch. I got this for around $26 on Amazon, it’s a unique way to cut metal, and you can pick this same one up by using the Amazon link in the show notes, which helps support my videos and the Cool Tools blog.
