Hey folks. I’m a “tinkerer” in my shop. (imagine that. A woodworker who tinkers with tools) I’ve been using Forrest blades for years but lately I’ve been toying with the idea of using a Ridge Carbide TS2000 because it has a ATB grind with a flat raker tooth as well. Thought it might be nice to be able to make flat bottomed grooves without having to set up the dado set or use a router, especially when I dont need to make a whole lot of grooves. I mean, on a 1/8” inch kerf, you run two pases and there you go, a 1/4” groove and the blade stays on the saw. I use a 1 1/2 horse contractor’s saw and the Forrest blades are thin kerf. I would like to try using a 1/8” standard kerf blade like the TS2000. Do I have enough saw power for the 1/8 kerf and is it really worth it to have an ATB-R tooth configuration? Thanks in advance for the help!

It’s worth noting that none of the ATB/R configurations actually leave a perfectly flat bottom, though they’re less pronounced that a standard ATB or Hi-ATB. In order for the ATB teeth to have any effect, they have to protrude slightly above the flat raker tooth, which in turn leaves slight “bat ears” or grooves along the edge of the cut. Even thought the 40T TS2000 has an ATB/R grind that’s a bit different than most 50T ATB/R blades, it’ll still leave slight grooves.

The TS2000 is a great blade that’ll perform pretty comparably to the WWII. Your saw should have enough muscle for a full kerf blade in most thicknesses if it’s well tuned, but I’d expect it to bog a little in thicker rips. You can always pick up a 24T TK ripper for those cuts. FWIW, Forrest will grind a WWII to an ATB/R configuration also, and both the WWII and the TS2000 are available in both 1/8” full kerf and 3/32” TK.

Thanks for the input. I DO have a 24 tooth rip blade from Freud. I also thought about just using that for the grooves when I need them. The saw is well tuned. It has a few aftermarket items on it that make it run better…....stainless steel pulleys, link belt, Vega saw fence. I’ve heard great things about the Ridge blade and I know I can get one with a discount from Holbren. I didnt know Forrest would grind what I wanted/needed. Thanks for that information!

I run a 40T full kerf CMT blade on my bosch 4000 job site saw without any issues.
Even when cutting 6/4 purpleheart.
I think you will have plenty of power.
