DeWalt DW3191 vs. Freud Diablo D07040A
Considering a new circular saw blade? Compare the features of the DeWalt DW3191 and Freud Diablo D07040A in order to make an informed purchase!
We’ll take a look at these two circular saw blades: the DeWalt DW3191 and the Freud Diablo D07040A.
Features & Benefits
Size
Both circular saw 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 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.
The DW3191 is 0.045” thick and cuts a 0.071” (thin) kerf. The Diablo D07040A is 0.04” thick and cuts a 0.059” (thin) kerf. (The term “kerf” refers to the width of the cut that the blade leaves in the material being cut.)
Teeth
Both saw blades have teeth in an ATB configuration. The DW3191 has 18 carbide teeth. The Diablo D07040A has 40 TiCo Hi-Density carbide teeth.
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, leading to cleaner crosscuts. They do have a tendency to be less durable than flat-top teeth.
Pros & Cons
Let’s take a look at some of the pluses and minuses of these products.
For the DW3191:
Pros
- Heavy-duty shoulders stand up to nails in wood with no kickback
- 18-tooth count makes for fast demolition and dismantling of wood
Cons
- Leaves rough cuts, not for precision work
For the Freud:
Pros
- Smooth cuts in both plywood and soft/hardwoods
- Thin kerf wastes less material
- Highly durable teeth last a long time
Cons
- Some retailers are still shipping the older (8,000 RPM) version
- Red coating sometimes smudges off on cut material
