The reciprocating tool is not used to build stuff, it is used to tear down or destroy things. A reciprocating saw is considered a demolition tool. A reciprocating saw is probably not going to be at the top of a list for tools most often needed, but when you need to destroy anything, it is the handiest tool in the world.
A reciprocating saw is a simple tool that has a motor that drives a blade back and forth. There are two main power types of saws, a corded and cordless saw.
Reciprocating Saw Feature
Cord – If you buy a corded version, make sure you get one that has a detachable cord. Since this tool is for destroying, most of the time you will have debris on the ground and you will be bound to cut the cord. A detachable cord is very easy to replace.
Orbital Action – Orbital action refers to the blade movement. A typical reciprocating saw moves back and forth, while an orbital saw not only moves back and forth, but it also moves up and down. Orbital action will help cut through material, except for pipe, a lot faster and easier. Make sure the tool has an adjustment that allows you to change the setting from orbital to a straight cut.
Strokes per Minute (SPM) – This is how many times the blade will move in and out per minute. It's a good way to gauge the speed of the tool.
Stoke Lenght – This is how far the blade will move back and forth. If you see a stroke length of 1-1/8″, this means the blade will travel 1-1/8 before moving in the opposite direction.
Shoe – This is the metal piece at the end of the saw, the piece that actually lays against your work. Some shoes are adjustable which means you can control the depth of the shoe. Adjustable shoes are great for getting the most use out of your blade.
