Which is better for framing and decking?

The DCS565B. Its brushless motor spins at 4,950 rpm and it cuts 2-1/8 in deep at 90°, so it handles 2x lumber faster. The DCS393 works but is slower at 3,700 rpm.

Is the DCS565B worth the extra $26?

Yes for daily use. You get a brushless motor, an electric brake and keyless blade changes. For occasional cuts, the DCS393 at $95.99 saves money.

Do both use the same 20V MAX batteries?

Yes. Both are DeWalt 20V MAX bare tools, so they run on the same battery packs. Neither listing includes a battery or charger.

The DCS565B's brushless motor has no brushes to wear out, so it should outlast the brushed DCS393 under heavy use. The DCS393's magnesium shoe is a durability plus.

Which is lighter to carry?

The DCS393 at 6 lbs, by 0.3 lbs over the DCS565B at 6.3 lbs. The difference is small.

Can both bevel to 50 degrees?

Yes. Both have a 0–50° bevel capacity. The DCS565B adds tool-free bevel adjustment.
