DeWalt DW3191 vs. Makita D-45989

We’ll take a look at these two circular saw blades: the DeWalt DW3191 and the Makita D-45989.

Features & Benefits

Size

Both blades have a 7 1/4” diameter and fit on a 5/8” diameter arbor. Typical circular saws have a 5/8” arbor and accept 7 1/4” diameter blades. This means that both saw blades should be widely compatible with many circular saws. If in doubt, check the manual for your saw to verify what size of blade your circular saw can take.

Both circular saw blades have a 0.071” (thin) kerf. The DW3191 has a plate thickness of 0.045”. The D-45989 has a plate thickness of 0.047”. (The term “kerf” refers to the width of the cut that the blade leaves in the material being cut.)

Teeth

Both products have carbide teeth. The DW3191 has 18 teeth in an ATB configuration. The D-45989 has 24 teeth in an ATAF configuration.

Alternate top bevel (ATB) teeth are cut on a bevel rather than being straight across. This shape allows them to slice through wood rather than chewing out chunks, resulting in cleaner crosscuts. They do have a tendency to be less durable than flat-top teeth.
