Hi I'm Dave Trull with The Trull Gallery, a custom furniture shop in St. Petersburg, Florida and I'm going to talk to you about the different kinds of circular saw blades. The blades I'm going to show you today are 10 inch blades, it's the most common size. If you're using a skill saw you might use 7.25 inch but most of your table saws, rip saws, panel saws, miter saws are going to use a 10 inch blade. There are 3 main blades that you would use on a regular basis. The first one I'm going to show you is a rip blade. It's used for cutting with the grain. They tend to have fewer teeth, in this case 24 and the reason they have fewer teeth is they need the extra space in the gullet which are these slots down here to pull out all that extra stock that they're cutting through. If you're going to cut against the grain or a crosscut, you would go to a crosscut blade. Now you're going to see considerably more teeth, this is a 60 tooth, they can go as high as 80 for a 10 inch, those are pretty standard, 60 to 80. They'll allow you to cut against the grain without a lot of splintering and give you a nice clean cut. The third blade is actually called a combination and it's exactly that, it's a combination of a rip and a crosscut. It's got deep gullets every fifth tooth and this is a pretty standard looking blade. These will come between 40 and 50 teeth. The advantage with this is it allows you to do both cuts but it doesn't do either one very well. Those are some of the more common circular saw blades you'll see. There are several others for different purposes but more specialized but they're all going to fall into these general categories.
