Best Power Mortisers
There is a big difference between using power and manual mortises. Power mortises are much faster and capable of handling larger pieces of wood. Manual mortises require more physical labor, but they have the advantage of being cheaper than their electric counterparts. Which one you should use will depend on what you’re trying to accomplish with your project, as well as how much time and money you want to invest in it.

When it comes to power mortises, there are a few things you need to consider Before making your purchase. Here is a handy guide to help you make the right decision for your needs.
