Size

Both table saw blades are a 10” diameter blade and fit on a 5/8” diameter arbor. Standard table saws have a 5/8” arbor and can accept blades up to 10” in diameter. Thus, both saw blades should be widely compatible with most table saws.

The 10” x 40T PrecisionTrim has a 0.098” (thin) kerf. The D1012LF cuts a 0.087” (thin) kerf. (The term “kerf” refers to the width of the cut that the blade leaves in the material being cut.)

A kerf smaller than 1/8” is known as a “thin” kerf. Thin kerfs waste less material than full-kerf blades and make it easier for saws to cut through thick or hard wood. Most, but not all, table saws can take thin-kerf blades. Make sure your riving knife is thinner than the kerf, or dangerous binding can take place.

Teeth

The 10” x 40T PrecisionTrim has 40 C4 carbide teeth in an ATB configuration. The D1012LF has 12 polycrystalline diamond teeth.

Blades having a tooth count under 40 are typically geared towards ripping wood lengthwise. For crosscuts or general-purpose use, you should consider options with more teeth. Blades having between 40 and 60 teeth are generally termed general-purpose blades. They will do an adequate job at ripping as well as crosscutting, but not quite as well as a blade specifically made for these cuts.

Alternate top bevel (ATB) teeth are cut on a bevel as opposed to being straight across. This design allows them to slice through wood instead of chewing out chunks, leading to smoother crosscuts. ATB teeth 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 10” x 40T PrecisionTrim:

Pros

Thick C4 carbide teeth with a precision finish
Very clean crosscuts
Good performance ripping hardwood and cutting plywood
More durable than blades with higher ATB tooth angle
Quiet when cutting, not much louder than when spinning
No chip-out when cutting material like melamine

Cons

Teeth are somewhat brittle and can be damaged if hitting nails or if used on metal
Some customers received blades with a noticeable warp or wobble

For the Diablo:

Pros

Diamond teeth are highly durable even when cutting laminates
Leaves very smooth cuts in laminate flooring
