Im in the process of upgrading from a craftsmen 110 to a powermatic 66. I have a decent combo blade from the 110 that is a thin kerf that i have no issues reusing it in the 66, but im about to order a Shark Guard/splitter, so if I am going to make the change to standard kerf with the more powerful engine, nows the time.

So what does the crowd say: stay w/ thin or jump into standard?

Not really feasible. Dont really care to buy a 2nd splitter and change it every time I change the blade.

I would go with the full kerf 1/8” blade for the best overall performance, 66’s are beasts, they will do the work fine with the full kerf blades.

If you want to measure the centimeters of wood you will save using the TK blades then do that. I don’t see that getting you better cuts though.

I’ve got a WWII thin kerf on my Delta and it does a fine job. I’ve had it for a couple of years. I just haven’t figured
out what I’ve gained over a standard kerf blade.

I’m pretty sure you can use a ‘thin kerf’ splitter with a full kerf blade <grin>

I’ll defer to those more knowledgeable, but from what I’ve read/watched, that’s not the safest option??

There’s very little reason to use a thin kerf blade, unless you have one and want to continue using it. With a left tilt saw, switching back and forth will make your fence scale off a little with one or the other unless you reset the cursor each time you change the blades. So if you intend to get a new blade, go with standard kerf, keep the TK around for when you send the other off for resharpening.

I hate combo blades as the do everything but nothing well.
Pick the blade for the performance. You will be amazed how well a 24 tooth full kerf works and how much smoother a good 60 0r 80 crosscut works.

Most full guards are full kerf splitters. You can get thin kerf MJ splitters and fit them to a throat plate. Please never run without a splitter of some type. Shame the 66 does not haver a riving knife retrofit but a splitter is better than nothing.

Did the same last year. PM66 with Shark Guard; went with the full-kerf splitter. Bought new blades. Kept my thin-kerf crusscut blade for my CMS and put my TK ripping blade on the shelf until I find someone to gift it to.

Have your say...
