A miter saw, often referred to as a chop saw or a miter box, is a specialized power instrument used in carpentry, building, and woodworking to make precise crosscuts and miter cuts in a variety of materials, primarily wood.

• Straight crosscuts, miter cuts (angles other than 90 degrees), and bevel cuts (tilted angles) are all made with miter saws.
• Circular saw blades with various tooth designs are generally used in miter saws for various cutting operations. The blade can frequently be changed out for another one that is made of a different material.
• Precision miter cuts are made possible by miter saws' ability to be modified to cut at various angles. The typical range for the angle adjustment is 0 to 45 degrees on either side.
• The bevel angle adjustment feature on some miter saws enables the blade to tilt for bevel cuts.
