   Oldham makes a circ saw blade especially for plywood. I'm sure there are other brands available but I bought one last year at Home Depot and it works great, no splintering at all. I think I paid 12 bucks for it.

   I just picked one up a couple days ago from HD. Made by Oldham, 60 tooth, carbide tipped. Best 7-1/4" blade for plywood that I've used. I think it ran about $11.00.

   I've been using one of those Oldham, 60 tooth, carbide tipped blades for a few years and they're great.  Virtually no splintering on ripped plywood and pretty minimal on crosscuts - even on birch.

   Thanks for the responses.  I picked up a 60 tooth blade, as well as a 140.  Used the 140 to rip the hardwood plywood.  It took a long time to make the cut, and did burn the wood, but there was almost no tearout or splintering.

   I now have burn marks on the blade though, probably because I'm not so good at using the saw!  Is there anything I can use to get the burn marks off the side of the blade so it won't 'stain' the next piece of wood I cut? 

   Also, could the fact I used a blade with so many teeth be the reason it took so long to make the cut (I was cutting down the entire length of a sheet of plywood, and the cut probably took 1-2 minutes)?

   Thanks again,

   Mark

   If we are thinking the same, I believe those 140 tooth blades are for thinner material, and the blade is not carbide tipped. Crosscutting plywood is the tricky operation. Ripping along the grain you can almost get away with any blade as long as your finished side is down.

   You can try a blade cleaner, sold in most woodworking stores. Some people use oven cleaner, but I have no experience with that.

   140 tooth blade? I wouldn't use it on ply. Mabey lexan or plexy. What does it say it is for?

   MIKEplease excuse my spelling.

   Another vote for the Oldham 60 tooth.  I didn't expect much from it for the price, but it leaves a remarkably smooth cut.

      Another vote for the Oldham 60 tooth carbide. Been using it for years to rip and cross-cut. Great value!
