Holy Shi$ am I seen you guys run in a circle chasing your tales?? Lmao
Ok what he means by why would anyone put carbide chain on there saw is this....
9A diamond wheel has to be used to sharpen carbide cutters. Stihl sells a diamond wheel for the USG grinder, and diamond wheels are available for other grinders. Unless you use carbide chain a lot, it is cheaper to send them away to have them sharpened. I think it cost me about $25.00 to have mine sharpened. The wheels are over $150.00. (I copied that from a previous discussion on these chains).
PS stop being so defensive in here, we are here to help not argue.
20 in. Oregon is $17-$20 for that saw. So you do the math. You are not sharpening that chain yourself. So its not cost effective to have that chain. If the previous owner wanted to waste his money (which looks like he did) on that chain, thats fine, but that chain is usually used for stumping (in dirt) roof venting(for fire dept) and other ruff stuff, that by the looks of that saw it wasnt used for any of that besides the person being sold on the carbide.
