DeWalt DCCS670 Chain — Best Aftermarket 16-Inch Replacement

If you own DeWalt’s 60V chainsaw, you’ve probably seen the same complaint pop up again and again in owner forums and community discussions: the saw itself is excellent, but replacement consumables can get expensive fast. The DCCS670 is one of DeWalt’s most popular cordless chainsaws, and while the stock setup works well, many owners eventually go looking for a more affordable chain replacement that doesn’t give up cutting performance.

That’s exactly why this aftermarket 2-pack has been getting attention. For DeWalt users who burn through chains doing storm cleanup, firewood processing, trail work, or routine property maintenance, paying OEM pricing every time can be hard to justify. A well-matched replacement chain at a much lower per-chain cost solves a very real ownership problem.

The Problem

Chains are wear items. Even on a strong cordless saw like the DeWalt DCCS670, the chain is one of the first parts owners end up replacing. In real-world use, several issues commonly lead to needing a new chain:

• Dulling from dirty wood: Cutting fallen limbs, roots, storm debris, or reclaimed lumber quickly takes the edge off cutters.
• Rock or metal contact: One brief touch to soil, gravel, fencing, or hidden nails can ruin an otherwise good chain.
• Stretch and tension issues: As chains wear, some owners notice they need more frequent adjustment or can no longer hold tension properly.
• Crooked cutting: A worn or unevenly sharpened chain can start pulling to one side, making cuts slower and less accurate.
• Poor chip ejection: Instead of throwing chips, the saw starts making fine dust, a classic sign the chain is dull.
• Extra battery drain: A dull chain forces the saw to work harder, reducing runtime and making the tool feel weaker than it actually is.

The big frustration, as many DeWalt owners mention, is that the OEM replacement chain often costs $25 or more for a single chain. If you keep a spare on hand, or if you routinely cut enough wood to rotate between chains, costs stack up quickly. That’s why aftermarket options only make sense if they truly fit correctly and cut well enough to be worth using.

Our Pick

Our recommendation is the:

2PC 16” CHAINSAW CHAIN BLADE For Dewalt DCCS670T1 DCCS670B DCCS670X1 DCCS623L1 DCKO667X1 16in. Brushless Battery Powered Chainsaw

• ASIN: B0C9DFF81G
• Price: $22.99
• Rating: 4.4/5
• Pack Size: 2 chains
• Chain Size: 16-inch
• Pitch: 3/8” LP
• Gauge: .043”
• Drive Links: 56DL

This is the kind of replacement part that hits the sweet spot for value. The specs match what DeWalt owners need for the DCCS670 platform, and the price is the biggest selling point: at $22.99 for two chains, you’re effectively paying about $11.50 per chain.

That matters because a single OEM chain is typically $25+. In other words, for less than the cost of one factory chain, you’re getting two replacements here.

Just as important, this isn’t only about price. A lot of cheap chains exist, but many are inconsistent in fit, sharpening quality, or durability. What makes this one stand out is that it’s been shown to cut just as well as the OEM chain in practical use. For most homeowners and even many heavier users, that makes it an easy recommendation.

Why it’s a good value

• Half the effective cost per chain versus OEM
• Correct specs for the DeWalt 16-inch cordless saw setup
• Good user feedback with a 4.4 rating
• Convenient 2-pack means you have a ready spare
• Comparable cutting performance to the factory chain

If you like to keep one chain on the saw and one sharpened backup in the garage or truck, this pack makes a lot of sense.

Compatibility

This chain is marketed to fit the following DeWalt models:

• DCCS670T1
• DCCS670B
• DCCS670X1
• DCCS623L1
• DCKO667X1

The key fitment details are the ones that matter most when verifying compatibility:

• Bar length: 16 inches
• Pitch: 3/8” low profile
• Gauge: .043”
• Drive links: 56

For the DeWalt DCCS670 series, those specs are the crucial match points. If your saw uses a 16-inch bar with 3/8LP, .043, 56DL, this is the correct replacement format.

A quick note: always verify the markings on your existing chain or bar before ordering, especially if your saw has had a bar change at some point. Some users swap bars or buy used tools with non-original setups, and that can cause confusion even when the model number seems right.

Installation Tips

Replacing the chain on the DCCS670 is straightforward, but there are a few gotchas worth mentioning.

Basic install steps

1. Remove the battery before doing anything.
2. Loosen the side cover and take off the bar/chain assembly.
3. Remove the old chain and inspect the bar groove and sprocket area for packed debris.
4. Install the new chain around the drive sprocket and along the bar.
5. Check chain direction carefully — the cutting edges on the top of the bar should face forward.
6. Reinstall the cover and set chain tension.
7. Tighten securely, then recheck tension after a brief test run.

Helpful tips

• Clean the bar groove before installing the new chain. Built-up sawdust and oil sludge can affect tracking.
• Inspect the bar rails for burrs or uneven wear if the old chain was cutting crooked.
• Don’t overtighten the chain. It should sit snugly on the bar but still pull around by hand with gloved fingers.
• Retension after the first few cuts. New chains often seat in and loosen slightly.
• Keep chain oil topped off. A good chain will still wear quickly if lubrication is poor.

If your new chain seems to cut poorly right away, the first thing to check is installation direction. A backward chain is more common than people think.

Why This Over OEM?

For most buyers, the answer comes down to cost, availability, and real-world performance.

1. Price advantage

The OEM DeWalt chain is often $25 or more for one chain. This aftermarket option gives you:

• 2 chains for $22.99
• About $11.50 per chain

That’s a major difference, especially if you maintain multiple chains or cut often enough to dull them regularly.

2. Better value for routine users

A lot of homeowners don’t need a premium-priced factory replacement every time, particularly when an aftermarket chain with the same core specs performs similarly. If it fits correctly, oils well, sharpens normally, and cuts cleanly, it does the job.

3. Proven cutting performance

This isn’t one of those bargain parts that saves money but creates frustration. The key point here is that this chain has been shown to cut just as well as OEM. That’s the deciding factor. If the cut speed and behavior are comparable, the lower price becomes very compelling.

4. Spare-on-hand convenience

Running a chainsaw without a backup chain is inconvenient. If you hit dirt or a rock midway through a job, your work stops unless you can sharpen immediately. A 2-pack makes practical sense because one can stay ready as a replacement.

5. Honest quality assessment

Is this necessarily better than OEM in every possible way? Not automatically. Factory parts still have the benefit of brand consistency and direct matching. But for buyers focused on function and value, this aftermarket set appears to deliver where it counts:

• correct fit
• acceptable finish
• strong price
• cutting performance comparable to stock

That makes it an easy alternative to recommend for most DCCS670 owners.

FAQ

Will this chain fit all DeWalt 16-inch chainsaws?

No. It fits specific models using 3/8LP, .043 gauge, 56 drive link chains, including DCCS670T1, DCCS670B, DCCS670X1, DCCS623L1, and DCKO667X1 as listed. Always confirm the specs on your current chain or bar.

Is this chain as good as the OEM DeWalt chain?

For practical cutting performance, it’s been shown to cut just as well as OEM, which is why it stands out. OEM may still appeal to buyers who want strictly factory-branded parts, but this aftermarket option offers much better value.

Do I need to sharpen it before first use?

Typically, no. It should be ready to install and use out of the package. That said, chain performance always depends on proper tension, bar condition, and lubrication. If cutting seems off, check setup before assuming the chain is at fault.

For DeWalt DCCS670 owners, this is one of those rare aftermarket parts that solves a common complaint without creating new ones. You get the right 16-inch 3/8LP .043 56DL fitment, a useful 2-pack, and a price that undercuts OEM dramatically. If you want a smart spare set for your saw without paying factory replacement prices, this one is easy to recommend.
