If you do a lot of home improvement work, then a reciprocating saw is probably one of the most important tools that you should have in your workshop or garage. A reciprocating saw is one in which the blade automatically moves back and forth at speeds of about 2000 strokes per minute or more, depending on the quality of the saw that you buy. These saws are controlled by a trigger or a speed dial, and the blade speeds are variable. This type of saw is sometimes referred to as a Sawzall, which is the name of the line of reciprocating saws produced by Milwaukee Tools.

Reciprocating saws are useful because they can cut through just about any kind of material that is generally found in homes. So if you whether you need to cut a hole in your sheet-rock (drywall), cut through a metal tube, cut some wood, or even cut through shingles, a reciprocating saw will serve you well. In addition, reciprocating saws can cut either up or down, which gives you a lot of flexibility when working in tight quarters. Though reciprocating saws are perfect for many different types of cutting applications in a lot of different situations, you shouldn't expect to be able to do anything that requires a great deal of accuracy or precision. That's not what these tools were made for.

When you shop for reciprocating saws, there are several things that you should look for. First, you should decide if you need a cordless saw or if a corded one will do. That makes a difference in price, of course, but could also limit your abilities to do certain kinds of jobs. Cordless reciprocating saws will allow you to go virtually anywhere, but corded ones may have more power.

Second, you should check out the blades that come with the saw and ask a sales person to show you how to change the blades. Assuming that you are not a woodworking professional, you'll probably be using your reciprocating saw mostly for household jobs. That means you don't really need a blade that's capable of cutting through steel or something like that. Also, it's very difficult to change the blade on some reciprocating saws, which is definitely a headache you don't need. So once you narrow your choice down to two models, go with the one with blades that are easy to change.

Finally, you should consider what size reciprocating saw you need. The bigger ones tend to be more powerful and more durable, but they are also bulky and not suitable for hard-to-reach places such as corners. Smaller reciprocating saws are just the opposite. You'll be able to work in tight spaces, but you'll probably be giving up some power. You have to think about what types of jobs you'll likely be using your reciprocating saw for, then make a decision from there.
