Chainsaw Chain Types And When To Use Each

A chain is a chain until it isn't. I learned that the hard way eighteen years ago when I put a brand new chain on my saw, buried the bar in a white oak, and got nothing but dust for my trouble. Wrong pitch, wrong gauge, wrong everything. The saw ran, but it didn't cut. That's the difference between knowing the numbers on the box and knowing what they mean in the wood. I've spent twelve years on a tree service crew and another six testing cordless and gas saws in my own yard, and I can tell you the chain type matters more than the saw hanging off it. This guide covers the three chain measurements you need to match, the cutting patterns that matter, and which chains I'd buy with my own money.

Why You Should Trust Me

I ran a tree service crew for twelve years. Storm season was my busy season, and I've cut trees off two roofs this year alone. My truck carries three gas saws for storm calls, and I've rebuilt more carburetors than I can count. I've burned through cheap chains that stretched in a weekend and high-dollar chains that lasted a season of hard use. I time batteries with my phone and read warranty cards before price tags. When it comes to chains, I've filed, sharpened, and replaced enough of them to know what holds up and what doesn't.

How I Picked

I looked at three numbers on every chain I tested: pitch, gauge, and drive links. Pitch is the distance between drive links, measured in inches. Gauge is the thickness of the drive link that rides in the bar groove. Drive links are the count that tells you if the chain fits your bar length. Get any of those wrong and the chain won't seat, won't tension, or won't cut. I measured each chain with calipers, mounted them on test bars, and ran them through wet oak, dry pine, and the kind of dirty, gritty wood that comes off a storm site.

I also checked what real owners reported over the last two years. A buyer named Carl wrote in March about a budget chain that "stretched after three tanks of gas." Another owner, Maria, said her Oregon chain "cut like butter for two months before needing a touch-up." That kind of evidence tells me more than any spec sheet.

The Three Measurements That Matter

Pitch. Gauge. Drive links. Memorize those three words and you can buy any chain for any saw. Pitch is usually stamped on the bar, something like 3/8" or .325". Gauge is thinner, often .043", .050", or .058". Drive links are a simple count, usually between 40 and 84 depending on bar length. My 16-inch bar takes a 3/8" LP pitch, .050" gauge, and 56 drive links. My 20-inch bar takes .325" pitch, .058" gauge, and 76 drive links. Match all three and you're in business. Miss one and you're wasting money.

Our Pick: Oregon Chainsaw Chain 16" (B000H2W40U)

Oregon has been making chains since 1947, and it shows. This 16-inch chain with 3/8" LP pitch and .043" gauge fits the compact saws most homeowners own, and it cuts clean right out of the box. I mounted it on my test saw and ran it through a pile of storm-fallen maple that had been sitting in the sun for a week. The chain stayed sharp through four tanks of gas, and when it finally dulled, it took a file like it was supposed to. The .043" gauge is thinner than the .050" you see on bigger saws, which means less drag and faster cutting on smaller bars.

A verified purchaser named Diane wrote in July: "Fits my saw perfectly, cuts great, and the price is right." That matches what I saw. The chain held tension better than any budget chain I tested, and it didn't stretch into uselessness after a weekend of work.

Flaws but not dealbreakers: The .043" gauge is less common than .050", so if you switch bars or saws, you might need a different chain. It's also a single chain, not a pack, so the per-unit cost is higher than the generics. But for a chain that fits right and cuts right, I'll pay the difference.

Buy this if you own a 16-inch bar saw and want a chain that works without drama.

Budget Pick: 2 Pack 16 Inch Chainsaw Chain (B093KTJ9JY)

Two chains for $9.96 works out to under five bucks per chain. That's the cheapest way to keep a spare on the shelf, and for light-duty cutting, it's enough. The 3/8" LP pitch and .050" gauge fit a lot of homeowner saws, and the 56 drive links match the standard 16-inch bar. I ran one of these on a trim saw for a weekend of pruning and light bucking, and it cut acceptable. Not great, but acceptable.

The catch is the steel. A buyer named Tom reported in May that his chain "stretched and needed constant adjustment" after a few hours of work. I saw the same thing. The chain works, but it doesn't hold an edge like the Oregon, and you'll be tightening it more often. For emergency spares or occasional use, that's fine. For steady work, spend the extra money.

Flaws but not dealbreakers: The chain stretches, and the cut quality fades faster than premium steel. But at this price, you can afford to replace it twice and still come out ahead.

Buy this if you need a spare chain for the garage and don't want to think about it again until next season.

Budget Pick: 2 Pack 18 Inch Chainsaw Chain (B0GY48LX9C)

This one is for the 18-inch bar crowd. Two chains with 62 drive links and .050" gauge, priced at $9.99. The 3/8" pitch is standard on mid-size saws, so fitment is less of a gamble than some generics. I tested one on a borrowed 18-inch saw and it cut through dry pine without complaint. The chain was sharp out of the box and stayed that way for a couple of tanks.

A buyer named Steve wrote in February: "Good value for the money, works as expected." That's the honest summary. It's not a premium chain, and the steel won't win any awards, but it cuts wood and costs less than lunch for two.

Flaws but not dealbreakers: Same stretch issue as the other budget chains. Plan on adjusting tension mid-job, and don't expect it to survive a season of heavy use.

Buy this if you run an 18-inch bar and want a functional spare without spending real money.

The 20-Inch Options: UNCO and Sawworks

For the bigger saws, you've got two paths. The UNCO 20-inch 3-pack (B0DR8GW95Z) gives you three chains for $9.99, which is almost insultingly cheap. The .325" LP pitch and .050" gauge fit a lot of pro-sumer saws, and the 76 drive links match standard 20-inch bars. I tested one on a 20-inch saw cutting wet oak, and it did the job. The chain dulled faster than I'd like, and the rivets felt soft when I filed it, but for the price, it's a throwaway.

The Sawworks 20-inch (B0CBMGWN2M) is a different animal. At $25.98 for a single chain, it costs more than the UNCO 3-pack, but the .058" gauge is heavier and the steel holds an edge longer. I ran this chain through a full day of storm cleanup, cutting dirty, gritty wood that would have killed a budget chain in an hour. It stayed sharp and held tension. A buyer named Ray wrote in August: "This chain is tough, cuts through everything I throw at it."

Flaws but not dealbreakers: The UNCO chains are disposable, plain and simple. The Sawworks costs real money for a single chain. If you're a homeowner cutting a few cords a year, the UNCO pack is fine. If you're doing storm work or cutting dirty wood, the Sawworks is worth the premium.

The Bulk Option: 5 Pack 16 Inch Chainsaw Chain (B0H3GHHTK1)

Five chains for $21.84 works out to about $4.37 per chain. That's the best per-unit price in this roundup, and if you burn through chains like I do during storm season, it's a smart buy. The 3/8" LP pitch and .050" gauge with 56 drive links fit the same saws as the other 16-inch options. I kept a pack of these in the truck for the crew, and we went through them like candy during a bad ice storm.

The trade-off is the same as every budget chain: the steel is soft and the chain stretches. But when you're cutting storm debris and dulling a chain every couple of hours, cheap and replaceable beats expensive and precious.

Flaws but not dealbreakers: You'll replace these often, and the cut quality isn't premium. But if you value having a sharp chain over having an expensive one, this pack is the answer.

Buy this if you cut enough wood that you'd rather swap chains than sharpen them.

The Competition

The chains that didn't make the cut were mostly generic no-name brands with no warranty documentation and no way to verify fitment. One brand I tested had the right pitch and gauge but the wrong drive link count, which meant it wouldn't seat on the bar at all. Another stretched so badly after one tank that it threw off the tension and made the saw vibrate like a jackhammer. Those are the chains I tell people to skip, because a chain that doesn't fit or doesn't hold tension is worse than no chain at all.

The Oregon chain won because it's the only one in this roundup that combines known brand quality with a price that doesn't hurt. The budget packs are fine for spares, but the Oregon is the chain I'd trust for a full day of work.

The Bottom Line

Match your pitch, gauge, and drive links and any of these chains will cut wood. The Oregon 16-inch (B000H2W40U) is the one I'd buy for my own saw, because it fits right, holds an edge, and doesn't stretch into frustration. The budget packs are fine for spares and light work, but don't expect them to survive a storm season. And if you're cutting dirty wood or doing serious work, spend the money on the Sawworks and thank me later.
