This is a decent die grinder kit. It comes with a case and a set of tools. It comes with 2 wrenches but one doesn't fit so it needs to be ground down if I want to use it. It comes with a 1/4" and 1/8" collet for the included tools. It has a rear-facing outlet. It's not the highest quality tool, but it's not a bad one at the same time. I have other pneumatic grinder tools and I will say that this one is quite noisy. Air tools of this type will generally be noisy but this one forces me to wear hearing protection as well. As for the grind - this works well with my little compressor. But the fact that it comes with a set of sanding attachments is a bonus.
