A chop saw is essentially a lightweight circular saw mounted on a spring-loaded pivoting arm, and supported by a metal base. Chop saws are considered the best saw to get very exact, square cuts. Compound miter saws have been developed due to the limited cutting capacity of the chop saw.

Chop saws can only be used for cross cutting of work pieces. The width of the work piece is generally limited to 4 - 6 inches. Material choices are generally limited to metal products. Consult the tool manufacturer's manual and cutting wheel specifications if you have any questions.
