Reciprocating saws make demolition easier and more fun. You can struggle and rip it out with a variety of crowbars and hacksaws or you can use a reciprocating saw and just cut it free. It's the ultimate demolition tool. Windows, walls, plumbing, doors and more—just cut and toss. Here's how to get the most out of your reciprocating saw.

What is a reciprocating saw?

Use framing components as a guide

Run your blade alongside framing to cut plywood sheathing. Brace yourself. Lock your knees into ladder rails. If possible, lean against something solid for support. This works for window and door openings, wall and roof ends, and anyplace else where you let plywood sheathing run wild. This technique also works during demolitionjust run the blade against the last framing member to stay.

The best demolition tool ever

Reciprocating saws, introduced in 1951, quickly became favored tools of contractors. Many of today’s saws have big 10-amp motors, variable speeds, no-wrench blade changing and 1-1/4 in. cutting strokes.

The reciprocating saw is a gateway tool. It’s the tool you’ll own when you graduate to a serious DIYer tackling a repair or major remodeling. If you buy one these days, expect to pay from $100 to $300, depending on the brand and the features. Would you rather try a reciprocate saw out for a one-time repair? Go ahead and rent one, but you’ll find that you’d rather have put the money toward buying one so you’ll have it again later.

We’ll show you a variety of uses for reciprocating saws, along with effective, safe ways to achieve professional results. A reciprocating saw isn’t used as a fine crafting tool. It’s a workhorse that gets its name from the short, back-and-forth cutting stroke of the blade. The blade is exposed so you can direct it into tight spaces. Because of this feature, you can use it in situations where other saws would be slow, impractical or pose a greater safety risk. Compared with a circular saw, a reciprocate saw is easier to control when you’re cutting above your head or working from a ladder.

The best blade for the best job

Use the right blade

Use a metal-cutting blade to slice through pipes. Brace yourself when cutting above your head. Dust and debris can shake loose while cutting in older ceilings; always wear safety glasses and a dust mask as needed.

By selecting the right blade, you’re able to tackle different tasks.

  • For cutting through metal pipes and nails, use a fine-tooth blade resembling a hacksaw.
  • When cutting through wood, use a coarse blade.
  • Use the coarsest-tooth blade to cut through plaster.
  • Some blades are toothless. They’re coated with tungsten carbide abrasive grit; use them for cutting stone, ceramic tile and cast iron.

You don’t always have to be finicky about choosing a blade. Use a nail-cutting wood blade to slash through roof shingles and plywood as well as nail-embedded 2x4s.

Most of the blade types come in standard 6-in. lengths. Smaller jig-saw-type blades are available, or select a 12-in. bladeuseful for reaching into deep recesses, cutting beefy landscape timbers and pruning trees.

Although tough, blades are not indestructible. They’re disposable and should be changed as often as you sense that a dull blade is slowing the cutting. Bimetal blades, with tool steel teeth bonded to a flexing spring steel blade, cost slightly more than carbon steel blades but outperform them. They’re tougher, cut faster and remain flexible longer.

If bent, blades can be hammered flat and reused. Even after the front teeth at the tip of your blade are worn down, you can still extend the blade’s life with this simple trick. Wearing safety glasses, use tin snips to cut off the tip at an anglethus presenting sharper teeth at the point of attack. Most manufacturers’ blades can be used on most brands of recip saws. Verify this before you buy.

Additional tips

Cut the nails, then remove the jamb

Remove a door jamb from its opening by cutting the jamb’s finish nails. This also works with window jambs. Grip the boot firmly when you can’t rest the pivoting shoe against the jamb.

Don’t forget the plunge cut

Plunge-cut through sheathing by placing the saw’s shoe against the roof decking as a pivot. Turn on the reciprocate saw and press the blade tip against the sheathing until it cuts a slot. You could also drill a 1-in. starter hole for your cut.

Note: installing the blade upside-down makes the angle between the blade and the surface you’re cutting more parallelwhich makes the initial plunge cut easier.

Start cutting through studs with a circular saw

Cut through wall studs fast. First, make a pass with a circular saw at its deepest blade setting and then finish the cut with the recip saw. The circular saw quickly does the bulk of the cutting. Its saw cut acts as a guide and starts the recip blade running level. Ease up pressure as you get close to the plywood; your blade tip could kick back.

Note: Watch out for electrical cable and plumbing pipes.

Using certain techniques will increase the saw’s effectiveness.

  • Applying proper pressure on the reciprocate saw is important. This is something that can be gained only through experience. It’s a balance between bearing down on the tool in some situations vs. keeping a tight grip on the boot for control in others.
  • Keep the saw’s shoe tight on the surface of the material you’re cutting. Doing so reduces vibration and increases cutting speed.
  • If you use a rocking, up-and-down motion with the saw, the work definitely goes faster.
  • Wonder how to get close enough to, say, cut nails behind lapped siding? Flip over the blade (teeth up) in the clamp assembly, then cut away. Avoid sawing into the siding.

Safety tips

Although recip saws are relatively safe, you must follow some rules.

  • Anticipate problems when cutting into walls and floors where electrical wires, heating vents and plumbing pipes may be present. Be especially careful with finished walls and floorsdon’t cut through wires or pipes.
  • Unplug the saw when changing blades and accessories.
  • Always wear your safety glasses. Hearing protection is recommended when cutting metal.
  • Recip saws are prone to kickback. If the blade pulls out of a cut and the blade tip bangs into your material, it’ll cause the saw to buck violently. This can happen suddenly and pitch you off balance. Remember this when working on ladders.
  • When cutting through pipes or wood, the blade can bind and cause the saw to buck. It’s like hand-sawing through a board that’s not supported under the cutthe saw stops cold. With a recip saw, the blade may be stopped, but the tool (and you) keeps jerking back and forth.
  • Blades generate plenty of heat. Just after making a cut, you can get a nasty burn grabbing the blade
    to change it.
