Does the 12 volt tools have the power to carry out basic tasks?
Yes they do. For example, if you use the MB150 rotary tool together with a cutting disc you can cut through a bolt or a nail. The advantage is that with the MB150 rotary tool you will be able to reach places you cannot reach with larger 110 volt tools. Please note that these tools have ample power to carry out intended tasks. You do not need to force the tool. These are precision tools and you should let the tool do the work.
