Looking for a blade to cut composite decking and wood. I see that Diablo has the Trex Blade,but there any reason that it won't cut regular wood also? Suggestions/Opinions?
A combo blade with around 40 teeth does a pretty good job ripping and cross cutting in hardwood softwood and plywood. Current issue of Fine Woodworking reviewing combos: Cleanest cut rip and crosscut on all wood, but slow ripping: Freud. Good rip speed but a little scoring on pine and a little chipping or fuzz on bottom of plywood:Forrest Woodworker II or Ridge."wood" is too generic for an accurate answer - that blade

is a "modified triple chip grind", made to keep from getting too hot and melting either trex or PVC.
I would think that it could MAYBE be used for occasional cuts on MDF or plywood (a "regular" TCG blade leaves a REALLY smooth edge), but if you were intending to do LOTS of cuts on ANY material, you'd be MUCH happier with a "job specific" blade for that operation - a "plywood" blade doesn't work for **** if you're RIPPING 2x6 fir into "2x3's", for example - it will burn up before you do just a few boards...
Conversely, a RIP blade (fewer teeth, different rake angle, etc) will make plywood look like you cut it with a chainsaw -
HTH... Steve
