Looking to purchase a new thin kerf rip blade for my 1.5 HP Delta Table Saw. After reading several reviews, I have narrowed it down between the Diablo and Marples both 24 tooth count. Any thoughts on which one would be a better purchase? Price is about the same, somewhere around $30. Has anybody tried both and have a favorite? I see a lot of Diablo blades being used in video posts and shop pictures, but hardly ever see any Marples. Thanks

Knotscott rates both equally there. I’ve not used either. I use 40T combination blades for ripping.

With a 1.5 hp motor you could use full kerf blade ,a LM72RO10 would be my first choice
It has thicker carbide teeth that can last longer than TK blades.can easily cut through 2” hard maple.

At what size motor should you stop using thin kerf?

I use the Diablo 24 tooth rip, 40 tooth combo, and the 60 tooth crosscut in my table saw. I like them because they are cheap and produce smooth cuts.
Before you invest in a tk blade, be sure the kerf will be wide enough for the riving knife or splitter on your table saw. If I remember correctly, the kerf on a Diablo is .098”

Both should prove to be very efficient at ripping, and neither is likely to leave an impressively smooth edge. Lumberjoe has tried both, and posted his findings here – http://lumberjocks.com/reviews/2934

I have tried the LM72 and the LU87, and can tell you that on a 2hp contractor saw and a 1.75hp hybrid, the LU87 was much easier to spin in thicker rip cuts.

I defer to knotscott on all blade knowledge but when I had my in my 1.5 HP saw, I can also say the Freud LU87 was the best blade I put in there.

How much more efficient is a 24 tooth blade then a 50 tooth combo blade at ripping stock? I have a 50 tooth already, do I need a 24 tooth also?

All of my blades are diablo I absolutely love them from their price point and performance. I have a 10in 50 tooth for ripping a 90 tooth for cross cuts on the table saw and a 12in 80 tooth on the miter saw no complaints here

For thick ripping the 24T is the way to go. Huge difference when you get much over 1” thick of dense hardwood.

24 teeth requires much less power for ripping then a 50 tooth blade for ripping. A full kerf blade will give you a much nicer finish than a thin kerf blade. You do need a 24 tooth blade for ripping and more so especially if you have a 1-1/2 hp saw. Also a dedicated rip blade has flat ground teeth as opposed to the alternating bevels of teeth on a combination blade which makes it cut easier and cleaner. Dedicated ripping and cross cutting blades will give you the maximum finish where as a combination blade is a compromise in both types of cut.

I have the freud ice blade. 24t bu it is thick. And the teeth are massive in width and length. I also have a delta/rockwell contractors saw.. older. The blade has made all the difference. The reason a 24t blade cuts faster (and works better in lower powered saws) is that it can move the sawdust out of the teeth faster. The cut is less smooth but I find that it’s still fine for gluing. Sometimes I pass it through the jointer after but not often.,

I don’t agree with that statement if you’re using high quality blades. In theory, if all else is equal, a full kerf blade should be less prone to deflection. Deflection with good TK blades was rarely an issue when I used them, and the finish was very comparable the vast majority of the time.

I’ve used a 40T thin kerf Diablo combination blade and a 24T thin kerf Diablo ripping blade on my 3hp cabinet saw and the main difference was the ability to run stock through the ripping blade at a much higher rate. The cut quality was only very slightly lower.

Looks like a need a 24 Diablo. Didn’t get much feedback on the Marples, I guess it isn’t very popular. Thanks guys and gals.

I use both a Freud Diablo and an Irwin Marples. Both are made in Italy and perform beautifully. I don’t think you will really notice a huge difference between the two. The Irwin has more carbide, so it may be a candidate for resharpening in the future.

What I’ll argue is the biggest difference between the two is availability. You can easily find the a range of the Freud Diablo at HD, whereas the Irwin is newer and more sparse if you want to see it in person before buying.
