Pressure treated lumber as well as “Wet Lumber” will require a special saw blade due to the the “gumming effect” caused by the heat from the saw blade when the lumber is cut. There are three main circular saw blades that you will want to use when you are doing numerous cuts are made by Bosch, DeWALT & HILTI.
DEWALT DW3174 Construction Series 7-1/4-Inch 20 Tooth ATB Thin Kerf Pressure Treated and Wet Lumber Cutting Saw Blade with 5/8-Inch and Diamond Knockout Arbor.
The best circular saw blade to use when you are cutting pressure treated wood is the thicker-kerf blade. These blades have bigger carbide teeth and the can also be re-sharpened.
I found that a good 24 tooth blade and my Compound slide saw worked well Almost any blade will cut treated lumber with no problem.
The most important thing about cutting pressure treated lumber that is fresh and probably pull the saw blade and give it a good bath in blader .
That means lots and lots of pressure treated 2x8s. What kind of blade should I use to cut pressure treated, presuming I DON’T expect the blade .
