Summary: Being a pipe welder I purchased this die grinder to help me prep my pipe on the inside for TIG welding with the use of flapper wheels. I wouldn't say that this grinder has a ton of power but defiantly enough to get the job done.
Summary: There is no way to adjust the speed on this die grinder. Sandpaper rolls should spin slower, but there is no way to do that with this Paddle switch die grinder. The technical details on the description say that it is variable speed, but it's not.
