Chainsaw vs Reciprocating Saw: Which One Should You Use on Wood?

In the chainsaw vs reciprocating saw choice, the chainsaw wins on logs, thick limbs and firewood, and the reciprocating saw wins on roots, thin stems and cramped cuts near the ground. A beginner should fell a tree with neither tool, and neither saw ever cuts at or above shoulder height. I look after a 3.7-acre orchard, and most of the wood I cut is small: dead plum limbs, hedgerow stems and roots by the drip lines. Below I compare how each saw cuts, what each one handles, and what each one asks of you for safety.

Chainsaw vs Reciprocating Saw: The Short Answer

Pick the chainsaw for logs, thick limbs and firewood, and pick the reciprocating saw for roots, thin stems and awkward cuts close to the ground. A chainsaw is built to cut wood. Milwaukee’s manual for its M18 FUEL Sawzall, the brand name many people use for any reciprocating saw, describes plunge cuts into walls and floors and cutting metal, and it never mentions trees.

• Choose the chainsaw if you cut logs for firewood, clear fallen limbs thicker than a hand saw handles, or cut a lot of wood in one session. For bucking logs at home and on the farm, I rank seven chainsaws for firewood in a separate roundup.
• Choose the reciprocating saw if your wood jobs are roots, thin dead stems, stubs and cuts where a chain would run into soil or stone.
• Choose neither if the tree is large, leaning, hung up on another tree, under tension after a storm, or near a power line. Those jobs belong to a certified arborist or the utility.

How Each Saw Cuts

The two saws remove wood in different ways, and that difference explains almost everything else in this comparison. A chainsaw drags a loop of cutters around a bar. A reciprocating saw pushes a straight blade forward and back. My guide on how a chainsaw works goes through the engine, clutch, chain and brake.

A Chain on a Bar

A chainsaw cuts as the chain travels around the guide bar, so it keeps cutting as long as the bar stays in the wood. The bar length printed on the box is the called length, and the wood the saw can cut through in one pass is shorter. On Makita’s UC4051A corded saw, for example, a 16 in bar has a 14 in cutting length. When I size a saw to a log, I count the cutting length against the log diameter, not the number on the box.

Alabama Extension puts bars of 8 to 15 in on light saws for small limbs and trees, bars of 16 to 20 in on midweight saws for thick limbs and trunks, and calls saws with bars over 20 in professional-grade and not recommended for homeowners. NC State says most household jobs rarely need more than a 16 in bar. My guide on what size chainsaw you need turns those bar ranges into a pick for homeowner jobs.

A Blade That Moves Back and Forth

A reciprocating saw clamps a blade in the front of the tool and drives it forward and back while a shoe at the front rests on the work. According to Milwaukee, the M18 FUEL Sawzall 2821-20 runs from 0 to 3,000 strokes per minute with a 1-1/4 in stroke, and the harder you pull the trigger, the faster it goes. The blade can be fitted with the teeth up or down, and the shoe slides to eight positions to use more of the blade.

What a Reciprocating Saw Can and Cannot Cut in a Tree

A reciprocating saw is a small-wood tool for me. I reach for it on a dead stem the thickness of a broom handle or a stub left after pruning, and I put the shoe flat against the wood before I pull the trigger. Milwaukee asks for the same: hold the shoe flat against the workpiece to avoid excessive vibration.

Wood that is not supported moves under the blade, and Milwaukee tells the user to secure and support the workpiece on a stable platform, because holding it by hand or against the body can cause loss of control. For me that means short pieces lying on a stand, not a limb still swinging on the tree. I use a reciprocating saw to cut tree branches only when they are dead, thin and below shoulder height, and I use only blades the maker recommends for the tool.

Reciprocating Saw vs Chainsaw for Pruning

Live fruit wood is mostly a hand saw and loppers job in my orchard. A chainsaw earns its place only on the rare limb that is too thick for them, and a reciprocating saw sits between the two. I keep it for dead wood and stubs, where speed matters more than a clean cut. For higher branches, I compare a pole saw and reciprocating saw to help you choose a pruning tool.

Both power saws share one limit: never cut at or above shoulder height, and never cut from a ladder or a roof. Clemson says the operator loses some control above shoulder height, the upper body is not protected by cut-resistant clothing, and a pole saw should be used for work overhead. My comparison of a pole saw and chainsaw covers that separate decision.

Small one-hand pruning saws are a third option, and each model has its own operating rules. Milwaukee’s manual for its 8 in pruning saw says to hold it with the right hand on the trigger handle and the left hand on the body grip, and to use one hand alone only to steady the branch, clear of the chain. I compare five cordless mini chainsaws for yard branch work in a separate roundup.

Using a Reciprocating Saw to Cut Tree Roots

Roots are where the reciprocating saw makes the most sense to me. A root lies in soil, and a chainsaw chain that touches the ground dulls fast; fine dust instead of chips tells you the chain is dull, according to the University of Georgia. A reciprocating saw blade is swapped at the clamp, and I treat blades as the part that wears out.

Roots also hide things. Milwaukee warns users to check the work area for hidden gas pipes, electrical wires and water pipes before blind or plunge cuts, and to hold the tool by its insulated gripping surfaces where the blade might touch hidden wiring. In my orchard the drip lines run on the soil near the trees, so before I cut a root I mark the line with stakes and keep the blade away from it.

Logs and Firewood: Where the Chainsaw Wins

A chainsaw is the tool for logs, and a reciprocating saw is the wrong tool for a firewood pile. The chain keeps the cut moving through thick wood, and the bar size is chosen for the log: Oregon State says the bar should be at least as long as the diameter of the largest tree you will cut, while the University of Georgia says slightly longer than the diameter. Both sources agree the bar must clear the wood, which is why I measure the cutting length. My guide on log splitter or chainsaw explains what each tool does with a firewood pile.

Battery and gas chainsaws suit different amounts of work. Alabama Extension says gas saws are more powerful, while battery saws are quieter, start with a button, need little upkeep and are powerful enough for most smaller jobs, with run time of about 30 minutes per battery in storm cleanup and two batteries recommended. NC State says battery saws are great for small, infrequent tree and shrub projects, not for prolonged use or large material. If you lean toward battery, I rank nine saws by bar, brake and battery kit in my battery chainsaw picks roundup.

I lift logs onto a stand before I cut them. The chain stays out of the dirt, and the wood is supported along its length so it does not pinch the bar.

Safety Compared: Chain, Blade and What Each Can Do to You

Both saws cut flesh, and both send people to the emergency room. A US review of 18,250 power saw and axe injuries over 2006 to 2016 found that power saws caused 89 percent of them, that most were lacerations to the fingers and hand, and that most happened at home (1). That review covers power saws as a group, not chainsaws alone.

What a Chainsaw Asks of You

A chainsaw injury series from rural Turkey counted 109 leg injuries and 76 arm injuries among 185 patients, and the authors conclude that protective gear and simple precautions can prevent such injuries (2). A separate hospital series of 41 leg injuries linked them to the foot sitting in the path of the saw, with the left foot hurt most often (3). Two hands on the saw, thumbs wrapped around the handles, body to the left of the chain line and firm footing are the starting rules.

Kickback is the reactive hazard of the chain. Laboratory tests on gas saws found that proper chain tension, anti-kickback links, guide bars with sliding ends and a quick chain brake influence kickback (4). Other tests show that the wood being cut and the spot where the bar tip touches it change the risk (5).

If the upper part of the bar tip touches wood or another object, the bar can kick back up and toward you (rotational kickback). Wood pinching the chain on the top of the bar pushes the saw straight back at you (pushback), and wood pinching the bottom pulls it forward, away from you (pull-in). A low-kickback chain, a chain brake and a correct grip reduce these risks; none removes them.

• Eyes: impact-rated safety glasses marked Z87+, with a mesh face screen only as an addition.
• Ears: hearing protection every time. Alabama Extension puts gas saws at about 110 decibels.
• Head: a hard hat when anything can fall from above.
• Hands and feet: gloves, and sturdy boots with ankle support.
• Legs: chainsaw chaps or trousers within their maker’s limits. Some makers state their material may not stop the chain of a battery or corded saw, and no garment guarantees protection.

Hold the saw with both hands, right hand on the rear handle and left hand on the front handle, thumbs and fingers wrapped around the handles, with your body to the left of the chain line and firm footing. Never use any rear-handle chainsaw with one hand, never cut at or above shoulder height, and never work alone. A gas saw also gives off carbon monoxide, so it never runs in a garage, a shed or any enclosed space.

What a Reciprocating Saw Asks of You

Milwaukee’s manual for the 2821-20 lists its own rules, and other makers’ manuals carry their own warnings, so read the manual of the saw in your hands. For the Milwaukee, hold the shoe flat against the work, keep the blade extending beyond the shoe and the workpiece through the whole stroke because blades may shatter if they hit the workpiece or the shoe, and never run the saw without its shoe.

Secure and support the workpiece on a stable platform, and wait for the blade to stop completely before you take the saw out of the cut. Milwaukee says the electric brake generally stops the blade within two seconds, may delay, and may occasionally miss. The manual also says not to use the tool if you feel the work is beyond your capability, and to contact Milwaukee or a trained professional for help.

Noise, Vibration and Fatigue

Both saws shake your hands, and both tire you. In a vibration study of groundskeepers in the southeastern United States, chainsaws gave the highest single-tool vibration reading, 8.0 m/s2 at the right hand, and some workers reached the 2.5 m/s2 hand-arm action limit across their workday (6). That is a professional measurement and I read it as a reason for breaks and for changing the job rather than as a number for a homeowner to chase.

For me the practical rule is simple. A sharp chain and a flat shoe cut vibration, a tired operator makes mistakes, and numb or tingling hands mean stop and see a doctor if it persists. Hearing protection stays on for a gas chainsaw from the first pull, and I wear it for a battery chainsaw too.

Which Saw for Which Job

Match the tool to the wood you actually have, then check the height and what is under the cut. This list is how I sort my own jobs.

Use hand tools for small live pruning, a chainsaw for substantial logs and limbs, and a reciprocating saw for suitable roots and confined cuts near the ground. Picking a battery or gas chainsaw is a separate question, and my comparison covers power, upkeep, noise and safety.

Before You Make the First Cut

Three things hold up every time: match the saw to the wood size, stay below shoulder height, and leave large or tangled trees to professionals.

My own habit is to walk the cut first and mark any drip line with stakes before the saw leaves its case. Read the manual for the exact saw in your hands, and take chainsaw training before your first real cut. Treat the chainsaw vs reciprocating saw decision as a question about the job in front of you: the size of the wood, the height of the cut and what lies underneath. If you are buying your first saw, my roundup of chainsaws for beginners lists seven saws with chain brakes.

Frequently Asked Questions

Can you cut trees with a reciprocating saw?

A beginner should not fell a tree with a reciprocating saw, or with a chainsaw. Felling is the most dangerous chainsaw job, and a large, leaning, dead or hung-up tree is a job for a certified arborist. A tree near a power line is a job for the utility’s qualified line-clearance crews.

Is a reciprocating saw better than a chainsaw?

A reciprocating saw is better than a chainsaw for roots, thin stems and tight spots near the ground, and a chainsaw is better for logs and thick limbs. The job decides, and both need eye protection and a firm hold.

Can I use a reciprocating saw to cut tree branches?

You can use a reciprocating saw to cut thin dead branches that sit below shoulder height and can be supported. For live fruit wood I prefer a hand saw or loppers, and anything overhead needs a pole saw or a professional.

Can you use a reciprocating saw to cut tree roots?

A reciprocating saw is a common choice for cutting tree roots because the blade is replaceable and no chain runs through the soil. Check for hidden pipes and wires first, as Milwaukee advises, and keep the blade clear of irrigation lines.

What should you not do with a reciprocating saw?

Do not run a reciprocating saw without its shoe, do not hold the work by hand or against your body, and do not change a blade with the battery in. Do not use accessories the maker does not recommend, and do not cut where hidden wires or pipes may lie.

Safety Note: Read your saw’s manual first and get hands-on training before your first cut. A chainsaw can react faster than you can: if the upper part of the bar tip touches wood or another object, the bar can kick back up and toward you; wood pinching the top of the chain can push the saw straight back at you, and wood pinching the bottom can pull it forward. Keep the bar tip out of contact and watch for wood closing on the bar. A low-kickback chain and a chain brake reduce these risks but never remove them. Before each use, inspect the saw as your manual describes: test the chain brake, and check the throttle lockout, the stop switch, the chain catcher, the guards and the chain. On a gas saw the chain must not move at idle. If any check fails or a part is missing or damaged, do not use the saw until it is repaired, and never disable a safety device. Wear impact-rated safety glasses with side protection marked Z87+ (a mesh face screen adds to them but does not replace them), hearing protection, chainsaw chaps or chainsaw trousers, work gloves and sturdy boots with ankle support, and a hard hat when you fell a tree or when anything can fall from above. Use leg protection within its maker’s stated limits: some chaps are not designed to stop the chain of a battery or corded saw, and no clothing guarantees protection. Hold the saw with both hands, right hand on the rear handle and left hand on the front handle, thumbs and fingers wrapped around the handles, and keep your body to the left of the chain line with firm footing. Never cut one-handed with a rear-handle saw, never cut at or above shoulder height, and never cut from a ladder or a roof. Top-handle saws are made for trained tree workers: follow that saw’s manual. Keep children, bystanders and pets well away while you cut. Never work alone. Start a gas saw with the chain brake engaged, on the ground or held firmly as the manual shows, never by drop-starting it, and at least 10 feet from where you fuelled it. Refuel outdoors with the engine off and cool, with no smoking, flames or sparks nearby, wipe up spills, and use only the fuel mix and ethanol content your manual allows. Exhaust contains carbon monoxide, which can kill: never run a gas saw indoors or in a garage, shed or other enclosed space. Before you touch the chain, clear a jam, adjust the tension or sharpen: release the trigger, engage the chain brake, stop the engine or motor and wait until the chain has stopped. Then, on a gas saw, let the engine and muffler cool and pull the spark plug cap off; on a battery saw, take the battery out; on a corded saw, unplug it by the plug. Put on gloves before you touch the chain, and release the chain brake only when your manual’s procedure calls for it. To carry the saw, stop it, take out the battery or unplug it, keep the chain brake engaged and the bar pointing behind you, and fit the bar cover for transport. Use a corded saw only with an outdoor-rated extension cord of the gauge your manual gives, plugged into GFCI-protected power. Never use it in rain or wet conditions: GFCI protection does not make that safe. Keep the cord away from the chain. Use only the chains and bars your manual approves. Felling trees is the most dangerous chainsaw job. Before any felling cut, keep everyone at least two tree lengths away, and plan and clear two escape routes angled back from the direction of fall; when the tree starts to fall, follow your manual’s retreat steps (release the trigger, stop the saw and set it down as it describes) and move away along that route; never delay escape to cool, unplug or cover the saw. A large, leaning, dead or hung-up tree, a trunk or limb under tension after a storm, and any tree near a house or a road are jobs for a certified arborist. Power lines are a separate danger: treat every downed line, and anything touching it, as live, stay well away and call the utility; before any work near a power line, contact the utility and leave that work to its qualified line-clearance crews. Stop when you are tired, and take breaks if your hands tingle or go numb.
