Terms of the Trade: What Is a Miter Saw?
A miter saw is used specifically to cut boards at an angle, and often to make miter joints, which are beveled edges meant to fit together such as in picture frames or molding. Miter saws were once only manual tools used in conjunction with a miter box, with the saw held on rollers. They have been replaced by the power miter saw, which makes quick and accurate cuts and is relatively portable. While the saw can be set at any specific angle to make a cut, there are standard presets including 15, 30 and 45 degrees.
