3/8 vs .404

[outsider]

On a stihl 880 wich chain would be best for ripping? 3/8 ripping chain or .404?

I use .404 on the 090/070, 3\8 on the 056 & 064

There will be very little in it.

 

The .404" is standard, so sprockets and bars are easier to get. The teeth are a bit bigger and the larger pitch means slightly fewer teeth engaged so it will clear chips better on wide cuts.

 

The 3/8" takes a slightly narrower kerf and engages more teeth at a time so nominally will cut faster and create less waste.

 

You don't get the same advantage running .404" as with an 090 or 070 as the revs are significantly higher and the torque significantly lower, so you can't just drop the rakers right away and take huge chips without it bogging down.

 

On balance, I go for the .404" as the advantages of standard parts (and slightly fewer teeth to sharpen!) outweigh the slight loss of kerf.

As above .404 is better - if you have the power to drive it then use it!

 

 

Kerf difference between the two is very small - speed of cut really comes down to skilled chain sharpening.

Ok, it'll be .404 then, when I get the saw and guide, I'll order the .404 chains at chainsawbars since stihl doesn't sell them anymore on Belgian market.

Thanks for the advice

Many thanks
