Overview
This carbide-tipped circular saw blade combo includes both 24-tooth and 40-tooth blades in the 6-1/2 inch diameter, giving you a framing blade for rough cuts and a finish blade for cleaner crosscuts in a single package. They serve as aftermarket replacements for DEWALT DWA161240 and DW3161. Compact 6-1/2 inch cordless circular saws are the workhorse of modern job sites, and keeping fresh blades on hand prevents bogging, burning, and ragged cut edges.

Installation notes
Remove the battery or unplug the saw. Press the spindle lock, then loosen the arbor bolt with the included wrench. Mount the new blade with the carbide teeth pointing in the direction of rotation shown by the arrow on the blade guard. Tighten the arbor bolt securely but avoid overtorquing. Make a test cut in scrap material to confirm the blade runs true and the guard retracts smoothly before starting finish work.
Common questions
Q: Will these 6-1/2 inch blades fit my DeWalt DCS391B and DCS565 20V MAX circular saws without any adapter?
Yes. These replacement blades are made for 6-1/2 inch saws and use the standard 5/8 inch arbor, which matches the DeWalt DCS391B, DCS565, DCS565P1, and DCS391P1 listed in the product title. As long as your saw is one of those 20V MAX models and uses a 6-1/2 inch blade, they should install directly with the factory arbor bolt and flange.
Q: What’s the difference between the 40T and 24T blades in this combo, and when should I use each one?
The 40-tooth blade is better for smoother, cleaner cuts in plywood, trim boards, and finish lumber where you want less tear-out. The 24-tooth blade is better for faster, rougher cuts in framing lumber and general construction material where speed matters more than a fine edge. Using the right tooth count for the job also helps reduce strain on your cordless saw.
Q: Do I need to do anything special when installing or maintaining these carbide tipped blades on my DW3161/DWA161240 replacement setup?
Make sure the blade is installed with the rotation arrow matching the direction of the saw, and confirm the blade seats flat on the 5/8 inch arbor before tightening the arbor bolt securely. For maintenance, keep pitch and resin cleaned off the carbide teeth and inspect for missing teeth, warping, or dullness before use. A dirty or dull blade can make the saw cut slower, drain the battery faster, and increase burning or binding.
