yet another saw blade post

Ok, I think i'm ready to upgrade my Mak 10" SCMS blade- its the factory 70t. I was seriously considering a Forrest Duraline thin kerf. as you know, it has a 40 degree HiATB and a 5 degree hook. The Chopmaster has 30 Degree ATB+R and a negative 5 degree hook.
I like the hi atb part of the duraline, as i would be cutting melamine and such... but isn't 30 degree pretty high too? What is the normal angle on ATB blades? Which of these two blades is more versatile- I won't have the luxury of multiple blades for specific purposes- so, mainly trim work, shelves... hard woods, MDF...

What other brands/specific models are comparable or worth considering?

Thanks,
jeff

This is the blade you want IMHO. I love this blade better than any other 80T I have ever used.

The Blade

Of course opinions vary and you will find die hard Forrest fans (like me) that won't try anything else (unlike me). Freud is making world-leader quality blades and usually for a few bucks cheaper.

Hi Jeff - Standard ATB angles range from 10-20, 30 is still quite high.

The Hi-ATB's I've used are the Duraline 100T, the LU80r010 (LU79 TK), A CMT ITK 255.080.10, and an Infinity 010-060 60T Hi-ATB. All cut very cleanly. That 40 of the Duraline and higher tooth count will leave the cleanest cuts but has a narrower "sweet spot", due to a slower feedrate so I don't believe that the Duraline is as versatile as the LU80, and neither is as versatile as the Infinity IMHO. The lower tooth count and slightly steeper hook (5) make the Infinity more versatile, but the 30 Hi-ATB grind will still makes very clean slices in crosscuts, veneers, ply, melamine, etc. (~ $70) Infinity also makes an 80T "Ultrasmooth" 010-080 that I haven't tried. The CMT ITK was very good but I think the others upstage it a bit.

The CMT's 15 degree hook is a small problem- but a great price. The LU80 seems about perfect, and cheaper than the Forrests, but is the LU79 being a thin kerf going to detract from any of the positives about the LU80? My Mak is the previous generation with the 13amp motor, and while its fine, I'd rather use a TK and go easier on it.

The LU79 will be more prone to deflection than the LU80 but should otherwise have nearly identical performance. Note that being "more prone" and actually having deflection are two different things...my experience has been that deflection is rare for most cuts with a high quality blade.

The Infinity 010-060 that I mentioned is on the thick side for a TK at 0.104".

The LU79 seems to be the answer. Nobody mentioned Ridge or Tenryu? Should i bother looking into them?

I've tried the Tenryu Gold Medal and Ridge Carbide TS2000...both 40T general purpose blades that are top shelf, but I haven't tried an 80T blade from either.

Ridge Carbide is analogous to Forrest....former Forrest employee, not far down the road from Forrest. They make one quality level...all top notch, US made, huge carbide....their 80T Hi-ATB is the MC10802 for ~ $110.

Tenryu has multiple lines and is either made in Japan or China depending on which line you end up getting....their Gold Medal is top of the line. Holbren sells the Ridge Carbide and Tenryu at good prices,

If TexasTimbers told me to buy ocean front property in Phoenix... I'd probably go ahead and buy the boat while I was at it.
The Freud blades have been my favorite, so far. Haven't used the CMT but I heard they're good.

ok, I was impressed with my Mak blade, just wanted better, and I could justify it. I got an LU79 this morning. HOLY COW! This blade is soooo smooth. I didn't think i had tear out before, cause I could brush off, or use my fingernail to clean up the edge. There's no such thing as tear out with the 79. It is truly fabulous. If a Duraline is double the price, there's no way its double the blade.

So, thanks for all the advice, i think i made a very wise choice.
