How to confirm the fit

  1. Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g. 3/8" LP .050".
  2. Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
  3. Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ

What size chain does a Kobalt KCS 180B-06 take?

The Kobalt KCS 180B-06 runs a 3/8" Low Profile or 3/8" Low Profile™ pitch, .043" / .050" gauge chain. Available bar lengths: 16", 18". Match the drive-link count to your bar (see the table above).

How do I know which gauge my KCS 180B-06 chain is?

Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the KCS 180B-06 are .043" / .050", .050".

Can I put a longer bar on my Kobalt KCS 180B-06?

Oregon lists 16", 18" bars for the KCS 180B-06. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
