@davidwyby , try getting this grind on Your semi chisel loops!

No Name (I received it in a care package from the US) , 3/8" , chisel , factory ground NEW



Ugly protruding rivet heads, I see them catching fibers and creating drag.

Oregon 091 , 3/8" LowProfile , semi chisel , factory ground , made some test cuts



Much less hook that the Dolmar 092 above!

I could use some help getting this to self feed on 42” 3120.

To me, the wheel never touched the corner of the tooth, and I agree with @Wilhelm, you went low into the gullet, going too low into the gullet hurts performance, makes the chain more grabby and robs power to do so

@Wilhelm wheel from wood turner’s wonders $75

I have some Stihl RM that seems to cut well and hold up well, I will try to emulate those angles as well. Also the Stihl guide for angles.

I probably should have put my .404 full chis skip loop on, but the wood was very dirty. You can see on the stump I had chip clearing problems.

I got Stihl RM from Sondre, I think I made some test cuts - I do not recall whether I liked it or not.

I have some small to medium diameter but muddy logs to buck at my neighbors.
I am uncertain whether I want to bother try semi chisel or just whip out the Stihl RD3 carbide loop.
I am seriously leaning toward CARBIDE!
My free time is too limited and valuable right now.

Could try the thinner 1/8” wheel with 40-45° of tilt from vertical

Thank You, correcting my post now!

Different cutters anyone?
Here it comes, stay tuned!

My speciality.

 

[Wilhelm]

Free hand ground HSS-Co 17.0mm drill bit.
In the chainsaw chain world this would be considered a mean full chisel square grind.

Shallow 140ish° angle, cross cut center, extreme "shoulder" back cut - makes one mean drill bit You don't want to use drilling free hand!

RM should cut pretty well. The side radius is so small it’s not far from full chisel

 

[Wilhelm]

Same drill bit "detuned" to be less aggressive.
Kinda like a semi chisel/square ground chainsaw chain hybrid.
I picked this mod up from WiDia solid carbide drill bits I had the pleasure to test run, IIRC they advertise this grind like "4 dimensional" or "4 corner" cutting edge - I'd have to look it up to be certain.

Dull 2.5mm HSS-Co drill bit






Sharpened/ground
