Do You Need a Sliding Miter Saw?
It depends on what you intend to do with your miter saw and how portable you need it to be. A non-sliding miter saw is all you’ll need for 90 percent of interior trim work. If you only have a few hundred dollars to spend and can sacrifice the wide cutting capacity of a sliding saw, we recommend buying a non-sliding compound miter saw instead. You’ll get a miter saw capable of top-quality work.
A sliding miter saw adds the ability to crosscut wide boards, which is handy for mitering wide baseboards, cutting up to 12-in.-wide shelves to length, or cutting extra-wide crown moldings. The downsides are the heft and the extra space the saw takes up—and the expense! For a permanently mounted workshop saw, it’s hard to beat a sliding miter saw. But if you plan to lug the saw from room to room or from one job to another, it’s not the best choice unless you need the extra cutting capacity.
