How to Select Table Saw Blades: Woodworking for Beginners #2 - Woodworkweb

hello everyone Colin Canet here for woodwork web today we're doing our second installment on videos for newcomers to woodworking and today we're going to talk about blades for table saws I often see new woodworkers getting very confused with what blades they should be using in their table saw and the first thing I can tell you is always buy an excellent quality blade it doesn't matter what your saw is like what counts is the quality of your blade and we'll put a link to how to select quality blades at the end of this today we're only going to talk about four types of blades you're going to make it very simple and very easy for you the first blade I want to talk about is the ripping blade and a ripping blade is used for natural woods for ripping for cutting with the grain and a ripping blade typically has 24 - maybe 30 teeth and you can see how big the teeth are and there's big gaps between them and there needs to be because that as the blade is spinning it needs to move a fiber out of the board so that's why you look for a ripping blade with only 24 teeth the next layer we want to talk about is a cross cut blade and you can see this one has 90 teeth lots of teeth on a cross cut blade compared to say a ripping blade and the reason that you have all of these small teeth because now you're cutting across the grain you're not ripping fibers out you're cutting across so you're really just making sawdust but you want to make a really nice clean cut so you need lots of teeth to do that and that's how you identify a ripping blade ripping blades often have 60 to 90 teeth the next blade I want to talk about is something called a combination some people call it a general-purpose blade and these blades are are good for rip and they're good for cross-cutting they're not as good as a crosscut and they're not as good as a ripping blade but for people who don't want to change blades or maybe they can only afford one good quality blade this might be something that you want to look at this particular one has 50 teeth which would be unusual for a ripping blade but it actually does a pretty good job of ripping and it does a very good job of cross cutting the advantage with a blade like this is you can put it in your table saw and you don't have to change from a ripping to a combination blade it does everything it doesn't do quite as good as a dedicated blade but it still does an adequate job the last blade that I want to talk about today is called a composite or multipurpose blade this particular one is 60t and this blade is for cutting MDF materials this is for all of your man-made materials plywood's MDF materials and the reason that we select the blade like this is because with things like plywood for example on your top layer you've got wood running this way your second layer it's going across it's going back and forth so with a blade like this it actually is doing a combination of cross cutting and ripping this blade your combination blade would also do an adequate job on ply woods and MDF but if you're doing a lot of MDF material or a lot of plywood this might be a blade that you want to look at the last thing I want to talk about today is how wide blades are and they refer to this as kerf and this blade here this is what we call a full curved blade and they're typically for a metric friends that's a little over three millimeters in imperial that's about a full eighth of an inch now the blade next to it this is what they call a thin curved and they're typically 3/32 or about two and a half millimeters and the difference between these blades as you can see there's a lot more carbide on a full curved blade than there is on a thin curved blade and what that means is this will stay sharper longer but it's also harder on the saw harder on the motor harder on the woodworker because it's taking off a lot more material this one here that little bit of thinner blade it's easier on the motor a little easier to be pushing wood through the saw but the blades don't stay sharp as long so that's the difference between thin curved and full curved so that concludes our video on table saw blades so now when you go to the hardware store you're going to have a much clearer idea how to select the kind of blades that you want in our next video we're going to be looking at the jointer and how to properly use the jointer to get the best results five minutes while making an expert on the joint here I'm calling connect for woodwork web don't forget to subscribe follow us on Twitter like us on Facebook you
