Overview

Ships as a 2-piece set, this chain is a direct replacement for KOBALT KCS 1224A-03 / KCS 1224B-03 Chain Saw - 2423633 models. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.

Key specifications

  • Bar length: 12”
  • Quantity: 2 chains per pack

Compatibility

Fits KOBALT KCS 1224A-03 / KCS 1224B-03 Chain Saw - 2423633 as a direct replacement for the factory chain. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.

Installation notes

Begin by shutting off the saw and disconnecting the power source. Loosen the bar-mounting fasteners and remove the side cover to access the chain. Slide the worn chain off, seat the replacement around the sprocket and into the bar groove with cutters pointing in the direction of rotation. Tighten the tensioning screw until there is slight play but no droop, then secure the cover.

Common questions

Q: Will this 2-pack of 12 inch chains fit my KOBALT KCS 1224A-03 or KCS 1224B-03 chainsaw?

Yes, these chains are made for the KOBALT KCS 1224A-03 and KCS 1224B-03 12-inch chainsaw models, including unit 2423633. As long as your saw is using the original 12-inch bar, these are the correct replacement chains for that setup.

Q: Do I need to do anything special when installing one of these chains on my 12-inch KOBALT saw?

After installing the chain, make sure the cutting teeth are facing forward on the top side of the bar and then set the tension so the chain sits snugly but can still be pulled around by hand. Run it briefly, then recheck tension because a new chain will usually stretch slightly during the first few cuts.

Q: How do I keep these 12 inch chains cutting well and lasting longer on my KCS 1224B-03?

Keep the chain properly tensioned and always make sure your bar-and-chain oil reservoir is filled before use, since a dry chain will dull and wear quickly. It also helps to clean sawdust from the bar groove and sharpen the cutters regularly, especially if the chain has touched dirt or wood with embedded debris.

Not sure which chain you need? See our guide: How to count drive links or Chain pitch, gauge & drive links explained.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (3/8 LP), gauge (.043"), and drive links (45DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 12".
  4. Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.

Frequently asked questions

How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.
