Weve also got a roundup of the best 10” table saw blades.

Size

Both table saw blades are a 10 diameter blade and fit on a 5/8 diameter arbor. Standard table saws have a 5/8arbor and can accept blades up to 10in 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 termkerfrefers to the width of the cut that the blade leaves in the material being cut.)

A kerf smaller than 1/8is known as athinkerf. 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.
