This so-called industrial grade tool is a waste of money. Based on my observations, it is poorly constructed and lacks power .The noise it emits is absurdly loud, but it doesn`t make up for the lack of torque. This is not a tool that I would want in my toolbox. The only upside is the price, but I would prefer to spend a bit more and get something that can actually do the job. Industrial and Scientific buyers beware..
Pros
High-speed grinding up to 22,000 RPM
Cons
Lacks variable speed control for more precise grinding
