Freud Diablo D07040A vs. Freud LU79R007
Considering a new circular saw blade? Compare the features of the Freud Diablo D07040A and Freud LU79R007 in order to make an informed purchase!
We’ll take a look at these two Freud circular saw blades: the Freud Diablo D07040A and the Freud LU79R007.
Features & Benefits
Size
Both products 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 Diablo D07040A is 0.04” thick and cuts a 0.059” (thin) kerf. The LU79R007 is 0.063” thick and cuts a 0.079” (thin) kerf. (The term “kerf” refers to the width of the cut that the blade leaves in the material being cut.)
Teeth
The Diablo D07040A has 40 TiCo Hi-Density carbide teeth in an ATB configuration. The LU79R007 has 60 carbide teeth in a Hi-ATB 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, leading to cleaner crosscuts. They do have a tendency to be less durable than flat-top teeth. Hi-ATB teeth have a steeper bevel angle than regular ATB teeth, and do a better job on materials like plywood and melamine.
Pros & Cons
Let’s take a look at some of the pluses and minuses of these products.
For the Diablo D07040A:
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
For the LU79R007:
Pros
- Leaves extremely smooth cuts in laminate, melamine, and other chip-prone materials
Cons
- Quite expensive, best saved for jobs where it really excels rather than general-purpose use
