Installation notes
Unplug or remove the battery before changing blades. Retract the blade guard, lock the spindle, and loosen the arbor bolt. Mount the new blade with the teeth pointing in the direction of rotation indicated by the arrow on the guard. Snug the arbor bolt firmly but avoid overtightening. Run a test cut on scrap lumber to confirm the blade tracks straight and the guard retracts and returns smoothly.
Common questions
Q: Will these 7-1/4 inch blades fit my DEWALT DCS578B and DWE575, or are they only for the cordless models listed?
Yes, these blades are sized for 7-1/4 inch saws with a 5/8 inch arbor, so they fit both the DEWALT DCS578B and DWE575 as long as your saw uses that standard arbor size. This set is intended for the listed DEWALT models, including corded and 20V cordless saws like the DCS590B, DCS577B, DCS573B, DCS574B, and DWS535B.
Q: What is the difference between the 24T and 40T blades in this DWA171424 / DWA31740 4-piece set?
The 24-tooth blades are better for faster, rougher cuts in framing lumber and general construction material where speed matters more than finish. The 40-tooth blades cut more smoothly and are a better choice when you want a cleaner edge in plywood, trim boards, or finish work.
Q: Do I need to do anything special when installing these blades on my DCS577B or DCS574W1?
Make sure the saw is powered off and the battery is removed before changing the blade, then confirm the blade is installed with the tooth direction matching the rotation arrow on the saw. It also helps to clean the arbor flange and blade seat before installation, because sawdust buildup can cause wobble or poor tracking during the cut.
