Comparing 2 different semi chisel chains. Stihl 36RM, Husqvarna S85

Comparing 2 different ways of achieving the same thing. The 36RM uses more of a chamfer chisel design compared to the rounder style of the S85.
This also shows why both chains end up with different side plate angles when filed using the same angle. The Stihl RM corner sits lower giving a 75 degree side plate vs the 60 degree of the Husqvarna. Both use a 60 degree top plate cutting angle.

Thanks for going to the trouble of setting up the side by side comparison - appreciated. At 15 sec the close up and lines you put in brings out the 3 sides on the Stihl 36 RM 'semi chisel' and shows the smooth curve on the Husky S85. Interesting to see the different physical constructions. I wonder what effects the different shapes have and how they vary with specific conditions. Did a quick google: If I got OK info, Chamfer Chisel a little more aggressive than Semi Chisel and might have an advantage in hard/dry wood but the Semi is a better at handling dirt and might do as well in green/soft woods. Got the comparison by reading some _'Canberra Diamond Blade'_ pages. They present info as if it's true to reality but I can't vouch for it. They seem to have a lot of info to help understand differences in performance to make purchase/use decisions. Cheers d

I'm happy someone else found it interesting, I just happened to have a new one of each and was curious to see what, if anything, was different between them. I might do the same thing with 404 chain later on. I have a bigger range of brands in that size.

thanks@@SawChainTheories I'm quite happy plodding along using semi-chisel on my 291 doing some firewood but after your vid and looking up chamfer chisel, I might give it a go some time. Won't need new chains for some time though. Cheers d

@@davidfenton3910 Nothing wrong with running semi. You give up some initial cutting speed for the extra durability and I think most people will cut more wood in a day with semi chisel. I bought both these to try and test how long full chisel chains hold their cutting speed advantage for because a lot of them drop off very quickly. Hopefully I'll find out in the next few weeks

I use the s85. How does the chamfered edge compare with that other chain? Is the chamfer more durable in dirty wood compared to the s85?

Stay with the S85 it's fantastic. Had 4 different 3/8 058 semi's with me and the S85 is the fastest cutting, Oregon DX is slower, slightly smoother and is the most durable. Stihl RM, I used to love it but when it's ran back to back with the others it was crap. Chatters and is rough cutting compared to the others. Had some Prokut stuff there as well, it's ok for the money but not great.
