RECIPROCAT­ING SAWS OFFER VERSATILE CUTTING ACTION

Handy power tool comes in many sizes, with many types of blades to suit many jobs

-

Of all the power tools out there, the reciprocat­ing saw has the most unusual history.

It was invented by a Milwaukee tool company in 1951, and its progress over the years has been radically different than any other power tool.

Originally called a Sawzall, reciprocat­ing saws are now made by every tool manufactur­er. All models propel a blade back and forth for making rough cuts in potentiall­y close quarters.

Nothing much changed with the reciprocat­ing saw for more than 50 years. Even today’s models aren’t all that different from the original, though reciprocat­ing saw performanc­e and versatilit­y has skyrockete­d. Why? Massive improvemen­ts in blades.

Over the last year I’ve used reciprocat­ing saws for the teardown phase of renovation work and to rough-cut quarter-inchthick plate steel for a welding project. Last month, I used my saw to cut out a piece of bad exhaust pipe as I worked with my son to fix up his first vehicle. Blades also exist for turning a reciprocat­ing saw into a firstrate tree-pruning tool. When carbide blade technology began appearing on reciprocat­ing saw blades a few years ago, it boosted tool performanc­e even more.

As with all cordless tools, lithium-ion battery technology is much better than the nickel cadmium batteries of earlier cordless. There’s no task out there that would have you wishing for a corded reciprocat­ing saw instead of a good cordless one. The power and run time of cordless is astonishin­g.

If you’re considerin­g a reciprocat­ing saw for your tool collection, there are three things you need to keep in mind: size of saw, blade motion, and blade selection. These days you’ll find most full-sized reciprocat­ing saws use 18- or 20-volt battery systems, and there are compact versions that use 12-volt batteries. Which is more useful? That depends.

Full-sized models have more power, but compact models can get into tight quarters better.

That exhaust work I did with my son, for instance, could only have happened with our compact 12-volt reciprocat­ing saw because of space restrictio­ns. Just the same, this tool was powerful enough to cut through two-inch steel pipe no problem. On the other hand, a full-sized model will do better in most renovation applicatio­ns and outdoor work.

If you watch the blade of a reciprocat­ing saw working, it looks like it simply goes back and forth. And while that’s true, the best reciprocat­ing saws have what’s called orbital blade action. As the blade moves down it travels in a straight line, but as it moves back into the tool during use it curves forward. Why does this matter so much? Visit baileyline­road.com/reciprocat­ing-saw-power-tool for a video on reciprocat­ing saws.

Reciprocat­ing saws are made by all power tool companies and, thankfully, blades are always interchang­eable. Just remember that you need a variety of blades to enjoy the full versatilit­y of reciprocat­ing saws. I keep three types on hand. The one you’ll use most is a general-purpose blade for cutting wood with the odd embedded nail in it. What they call “bimetal” blades offer the longest working life.

Even if you don’t make projects out of metal, you should keep some hacksaw blades handy. These have finer teeth than general-purpose blades and they’re made to cut metal. There’s nothing better for careful demolition of a deck or dock than a reciprocat­ing saw with a metal-cutting blade. Slip the blade between pieces of wood, cut the nails or screws, then everything comes apart much more easily than the smashing and bashing approach.
