This is a small tool that you would not want to use on a big project it is good for small detail work. And i find that it is very good for sharpening tools like chisels and axes etc. It is very easy to handle and use it is very cheap it was like 20 dollars i got it at Lowes. it came with the tool a battery a sander bit a grinder bit a polishing bit and a small wrench to change the bits out with. this is not a strong tool but over all it is a pretty good tool.
