Topic tags/keywords: table saw blade size more rip cross cut tablesaw joining finishing

I’m just curious as to what type of blades we use most on our table saws, tooth count, kerf size, rip blade, cross cut blades and the list goes on with options available for table saw blades. Most of my work is on solid wood pieces usually thicknesses between 1/4” to 2 1/2” and starting with rough cut boards. I have a 10” table saw 2 hp, general 185 left tilt, contractor mounted on large rolling base with router table.

I use CMT 1/8” kerf blades, my go to blades are a 10” Glue line rip blade, 30 tooth, as well as a 10” Compound mitre Cross cut 80 tooth blade. I change between these two blades as required and they have performed perfectly for me and my projects.

8” Dado stack is used and makes oh such nice smooth flat bottoms.

I did find a thin kerf blade in my collection but don’t recall knowingly using it.

So what do you use for your table saw go to or default blade/s ?

Full kerf blades yield cleaner cuts. The only reasons I use
a thin kerf is with a 110v saw.

My blade inventory is down to a measly 25 ready to go blades that I have on hand. I’m currently running a 3hp cabinet saw, and have gradually replaced my thin kerf blades with full kerf simply because there’s less incentive use TK blades now. When I had a 2hp contractor saw and 1-3/4hp hybrid, the saws had a noticeably easier time spinning a good TK blade. I tend to keep a good 40T Infinity Super General or 50T DeWalt ATB/R general purpose blade in the saw for convenience, but I’ll switch to a specialty blade when there’s a need…..60T Infinity Hi-ATB or 80T CMT Hi-ATB blade for more critical fine crosscuts and plywood, or a 20T Amana ripper if I have a lot of heavy ripping to do. I keep an 80T Leitz on my CMS.

There are pros and cons to each kerf width. I don’t believe you can make a valid absolute statement that all full kerf blades make cleaner cuts than all TK blades. There are good and poor examples of each, and it’s hard to tell the difference between the good ones…which is best is a matter of preference and circumstances. Both kerf widths will work with most saws, but a full kerf blade is typically 33% thicker than it’s TK counterpart, and requires more power to make the same cut. If all else is equal, a thicker blade will tend to be more stable than a thinner blade, but if the blade is well made, it generally requires some lateral pressure to make any blade deflect significantly. Sharpness and basic quality are key in either kerf width….keeping them clean, will yield better results and will keep them sharp longer. It’s especially important that your blade is at least as wide as your splitter or riving knife, or the work piece will bind.

I’m not one that likes to changes blades on the table saw, call me lazy :) I have an older Hitachi C10FL 10” Table Saw that’s no longer made that I purchased from Lowes many years ago, since I do a lot of box and finger joints, mitered splines and such I’ve been using the Forrest single grind 1/8” flat kerf blade and just use it for everything, in the miter saw I have a low end avanti 60 tooth finishing blade.

I hate math… and figuring with a full kerf 1/8in. blade in the mix, is a lot easier! ;-)

I have a 1.5 HP contractor saw, so power is somewhat of an issue. For a long time, I used a Forrest WWII full kerf combination as my main blade, and I was very happy with it. (The reason I went with full-kerf at the time is that the thin-kerf blade that came with my saw had hang-up issues with the blade-guard/splitter assembly.)

After I ditched the OEM splitter for a Micro Jig splitter setup, I decided to see how a good quality thin-kerf would perform. I bought a Freud Fusion TK combo blade that I saw several folks recommend, and I run it with a blade stabilizer. The cut quality is every bit as good as the Forrest full-kerf, and the saw does not struggle at all now. It’s like a hot knife through butter. Needless to say, that’s the blade that stays on my saw now, unless I’m using my dado stack.

At 2 HP, I guess you might be sort of on the borderline. I think it would be worth your while to try a good thin-kerf blade. You might find enough improved performance to make you think about sticking with it.

2 things will dictate full kerf vs thin kerf; hp and depth of cut. Lower hp saws definitely benefit from thin kerf as they are take less muscle to spin through the wood. However, as the depth of cut increases the likelihood of blade warp increases exponentially. Stabilizers help, but also limit the depth of cut. When using a contractor style saw I typically use a thin kerf blade, but our cabinet saws are all full kerf.

If you’re getting good results with full kerf blades, there’s no reason to change. I doubt you’ll see any improvement and more likely will see degraded cuts.

Full kerf combo, thin kerf ripper, thin 80 th. crosscut are the standards for my shop. I have multiples from Freud, Onsrud, and Infinity.

I use a Forrest WWII full kerf on my 1 3/4 hp Sawstop. It has plenty of power to use a full kerf blade so I don’t see any reason for the thin kerf blade. I don’t like changing blades a lot either so unless I need to use my dado set I just leave the one blade on and it works good for me.

Geoff, I use a variety of 8” Skill saw blade configurations in my table saw unless I really have a thick piece to cut. Why, because they are cheaper. But that is just me. Currently I have an 8” thin kerf 40 tooth combination blade on my saw that has lasted for a long time.

I usually have a Delta ATB combination blade mounted up as I have several on hand. If I’m cutting something that’s could damage or quickly dull the blade, I’ll use a thinner kerf Freud Diablo blade. If I’m making several cuts where minimum kerf is required and surface finish and speed aren’t high priorities, I’ll use a much smaller, very thin kerf blade for a cordless circular saw. This is only done when the bandsaw won’t work for what I’m trying to accomplish.

My normal usage includes examples of Forrest WWII 40t, Chopmaster 80T, Freud 18, 24, and 30T rip blades, and a melamine blade, all full kerf. I have two of most, one is either unused or out for sharpening, the other is in use. A pair of 24T rips are married, and mated to spacers for dual blade tenoning.

I don’t keep track of the stack that I don’t use…
