Best Type Of Circular Saw Blade For Wet Or Pressure Treated Wood

Choosing the correct saw blade will make all the difference in the quality of cut you get. If you have to cut a lot of wet wood it will take all day if you try and use that multi-purpose blade that came with your circular saw.

You really just have two ways to go here: use-and-destroy or use-and-maintain. The use-and-destroy way recommends buying a lot of thin-kerf blades (.059-inch) cheap and throwing them out when they get dull. When they’re new and sharp, they cut fast. If you hit a few nails, though, that’s it. At less than $10 a piece, that’s not such a big loss.

Many carpenters choose a thicker-kerf blade (.091-inch) that you can maintain. Thicker blades have bigger carbide teeth; they hold up to nails better and you can re-sharpen them to keep them in your fleet longer. However, you’ll pay more for them–upwards of $20.

When you want straighter cuts and rips or if you’re doing any kind of fine work like using a shoot board to cut built-in parts, stay away from thin-kerf blades–especially dull ones. Even sharp thin-kerf blades can deflect and leave you with a lower quality cut than a stiffer, thicker-kerf blade.

Many thin-kerf blades have aggressive hook angles (20 degrees or so) for faster cutting, but they can add to tear-out. Combination blades generally have lower hook angles of about 12 degrees and exit the work more cleanly.
