Are these the same chain?

Yes. Both carry part number DWO1DT612: 12-inch, 45 drive links, 3/8-inch pitch, .043 gauge, semi-chisel, low kickback. The only real difference is pack size and seller terms.

Which is the better deal?

Product A. At $18.97 at Amazon as of November 4, 2026 you get two chains, about $9.49 each. Product B is $18.97 for a single chain at the same store.

Will either fit my DCCS620?

Yes, both list the DCCS620. Product B also lists the DCCS621B and DCCS620P1, so check your model plate if you own one of those.

How long does a chain last?

It depends on cutting volume, wood type and sharpening. Keep the chain oiled, tensioned and sharpened, and a homeowner can usually get a full season or more from one chain. Buying the two-pack means a spare is on hand.

Can I return Product B?

Some stores list it as closeout, final sale, not eligible for return. Check the seller's terms before ordering. Product A has no such restriction stated.

Do I need tools to install it?

Product A states adult assembly is required and tools are not provided. You need a bar wrench and a file guide for sharpening; neither is in the box.
