Best saw chain grind angle?

[ketch]

Been cutting dead red oak. 25 to 30 inch dia. stuff. HARD! What do you guys think would be the optimum grinding angle for the chain?

35 deg on top.

Is it "hard" and lugs the saw way down , or "hard" and dulls the cutters to fast?

As 30 deg with a slightly lower depth-gauge will stay sharp a little longer and keep a good chain speed in oak.

I've been real happy with 25 degrees. Run a full comp and full skip on a 24" bar with the 036 and it pulls just fine. Throws nice chips. Haven't played with angles for the 36" bar on the 660 yet. Probably will sharpen everything at 25 degrees unless someone tells me 30 degrees will get me faster cut times and keep the chain sharp longer.

same here, I've been running 25 degrees. Seems to work best for me. Tried 30 and 35, I like 25 better.

I run 30

What chain are you running ?

He said hard, not soft.........

Chain

I am cutting with my old 084 AV. The chain is the one that came with the saw and I am not sure which one it is. The saw of course has lots of power but in this stuff never spit out big chips like I would think it should.
The chain is over half used up. Maybe I should buy a new chain?

On the 084 (Oregon 59L chain) I use 25 deg for "hard" stuff. It stays sharper longer, especially if you have to crosscut the blocks to make them more manageable. Otherwise 30 degrees.
