When considering a jigsaw or a reciprocal saw, it is important to understand that a jigsaw is a type of reciprocating saw. They both use a push and pull motion to cut through material. Reciprocating saws are good to use if the object being cut is out in the open and easy to see, like cutting pipes or nails. A jigsaw cuts with more accuracy than a reciprocating saw, and is ideal for cutting counter tops and cuts that need more accuracy. Within Milwaukee Jigsaws, some of the battery platforms include Milwaukee M12 and Milwaukee M18.
