What Is a Reciprocating Saw?
A reciprocating saw, also known as a recip saw or saber saw, is a power saw that cuts like a hand saw. The electric saw motor moves the blade in a back-and-forth — reciprocating — or an elliptical pattern to cut through the workpiece. The aggressive cutting action of a reciprocating saw makes it a useful power tool for jobs ranging from demolition to cutting tree limbs.
Key Parts of a Reciprocating Saw
- Blade Clamp: The fitting that holds the saw blade
- Shoe: A pivoting plate that rests against the workpiece, providing leverage and typically allowing you to cut from different angles
- Trigger: The switch that starts the saw
- Lock-Off Button: A setting that locks the trigger in the OFF position for safety
- Rear Grip: A D-handle or pistol grip that allows you to hold the saw while operating the trigger
- Forward Grip: On a standard saw, a grip near the shoe that lets you direct and steady the saw with a second hand
Matching a Reciprocating Saw to Blades and Attachments
Not all reciprocating saw blades work with all saws, so check the specifications for your saw to purchase blades that fit. Make sure a saw blade is right for the material you’re cutting, whether it’s wood, masonry, pipe, metal or nail-embedded lumber. Blade specifications determine what and how a blade cuts. Key blade specs include:
- Length
- Width
- Thickness
- Material
- Teeth per inch (TPI)
Look for reciprocating saw blade sets that include a variety of blades for different uses. See our guide to choosing reciprocating saw blades to find a blade that’s right for your saw and projects. In addition to saw blades, look for reciprocating saw attachments like scrapers, grout removers and brushes that increase the versatility of the saw.
Types of Reciprocating Saws
Consider design and power source when deciding on a reciprocating saw type.
Reciprocating Saw Designs
Full-Size Reciprocating Saws Cut Faster
A standard, full-size reciprocating saw requires two hands to operate. With a larger body, and a rear and forward grip, this type of saw is heavier. But it accepts longer blades that cut faster, so it’s good for larger jobs.
Compact Reciprocating Saws Are Lighter
A compact reciprocating saw cuts where larger saws won’t fit. It typically takes shorter blades, so it doesn’t cut as fast as a full-size saw, but models with a drill-like pistol grip allow one-handed use. The lighter weight of this type of reciprocating saw reduces fatigue. This saw is good for smaller jobs when the speed — and weight — of a standard saw isn’t necessary.
Battery-Powered Reciprocating Saws vs. Corded Saws
Battery-Powered Reciprocating Saws Offer the Best Portability
Without the restriction of a power cord, a battery-powered or cordless reciprocating saw lets you work just about anywhere. You also don’t have to worry about the cord getting caught on obstructions. High-power batteries give you cutting power, but heavy use can drain the battery. Having a spare battery ready lets you keep working. Cordless reciprocating saws are available in full-size and compact models.
When shopping for a cordless reciprocating saw, pay attention to the battery platform. Tools on the same platform let you swap batteries among equipment, so you can always have a spare ready.
Corded Reciprocating Saws Offer Constant Cutting Power
Uninterrupted power is a key benefit of a corded reciprocating saw, and the lack of a battery means a lighter saw. These factors make a corded saw a good option for larger, longer jobs. Corded saws are usually full-size models. Remember to factor in the cost of an extension cord that can handle the current the saw draws. Follow the manufacturer’s cord specifications and read our guide to power cord safety for tips on matching an extension cord to your saw
Reciprocating Saw Uses
Aggressive cutting and versatility make a reciprocating saw a great addition to your tool collection. Follow your saw and blade manufacturers’ instructions for use, but depending on your saw and blade you can:
- Cut through studs, joists and rafters for demolition or remodeling projects
- Cut through sheathing for windows and doors for a home addition
- Cut through walls or subfloors to run pipe or electrical wiring
- Cut pipe when repairing or rerouting plumbing
- Cut ductwork to configure a heating, ventilation and air conditioning (HVAC) system
- Cut small branches to prune a tree or shrub
Reciprocating saws also let you make flush cuts, for example cutting a post even with a concrete pad or cutting a wall base plate away from the subfloor
As useful as a reciprocating saw is, it’s not the best tool to use when accurate measurements and precise straight or angle cuts are priorities. A circular saw or miter saw are better options for this type of work. Our circular saw guide and miter saw guide help you compare features and uses.
Top Features for a Reciprocating Saw
Look for these reciprocating saw features to improve efficiency and convenience.
Cutting Power
Higher-voltage (V) cordless reciprocating saws and higher-amperage (amp) corded saws generally mean more power for cutting. With a cordless saw, runtime is a factor in how useful the saw is for large projects and tough cutting. High amp-hour batteries typically let you work longer.
Strokes per Minute
Cutting speed is a key benefit of a reciprocating saw and the number of strokes-per-minute the saw generates helps compare speed among models. More strokes per minute means faster reciprocating action and cutting.
Blade Stroke Length
Stroke length also affects cutting speed. Longer blade strokes mean faster, more aggressive cutting. You usually find the longest blade stroke lengths in full-size reciprocating saws.
Variable Speeds
A saw with a variable-speed motor lets you adapt cutting power to your project. Use higher speeds for quick cutting and lower speeds when you want more control and precision, and when cutting metal.
Adjustable Shoe
An adjustable shoe lets you configure blade depth for better control over your cuts. Adjusting the shoe can also let you cut with different sections of teeth, extending blade life.
Brushless Motor
A brushless motor on a reciprocating saw adapts power output according to the needs of the work and runs cooler. This means the saw uses the battery more efficiently and can last longer than a comparable saw with a brushed motor. Read our guide to brushless and brushed motors to see how the two motor types compare.
Other Reciprocating Saw Features
- Orbital cutting action uses an elliptical blade action intended for fast, rough cutting through softer materials, such as softwoods.
- Multi-position blade clamps let you orient the saw for the most effective cutting.
- Tool-free blade changes reduce down time.
- Built-in lights make cutting easier in tight or dark spaces.
Reciprocating Saw Safety Tips
The high-power cutting and exposed blade of a reciprocating saw require full attention to safety. Follow the safety procedures in your saw and blade documentation, but here are key safety tips to remember:
- Wear the right safety gear, such as safety glasses, hearing protection and, depending on the situation, a respirator and hard hat.
- Use the right blade for the saw and the material you’re cutting.
- Wear heavy-duty work gloves when installing blades.
- Be aware of hazards like electrical wiring, water pipes, gas lines and other potential hazards in the project area.

Frequently Asked Questions on Reciprocating Saws
The answers to these common questions about reciprocating saws can help you find the right saw and use it correctly.
Can a Reciprocating Saw Cut Metal?
With the right blade, a reciprocating saw can cut several types of metal, including nails, pipe and rebar. A variable-speed saw lets you use a slower cutting speed that’s effective for this type of work.
Can I Cut a 2-by-4 With a Reciprocating Saw?
Yes, a reciprocating saw with a wood cutting blade can quickly cut through a 2-by-4. Just make sure the board is properly secured or clamped to avoid pinching the blade and kicking back the saw toward you. Keep in mind, a reciprocating saw is best for rough cuts and demolition, where speed is the priority.
Should I Buy a Reciprocating Saw or a Jigsaw?
A reciprocating saw is the best saw for demolition work, heavy-duty cutting and projects where cutting speed is more important than detail and accuracy. A jig saw doesn’t have the power of a reciprocating saw and is better for work where precision is important, such as cutting curves or intricate designs.
