The XOMO grinder is a beast when it comes to grinding. Based on our own experience this product has a sturdy build and is built to last. The 12000RPM grinding capability ensures that every job is done efficiently and quickly. The pros of this product include the strong motor and the ability to handle tough materials .The only con we have found is that it may be a bit too bulky for some users. Overall, this is a great industrial power TOOL that should definitely be considered for heavy duty jobs..
