Are any aftermarket chains good or should one just stick with OEM?

Yes -- based on the bar you have .325" pitch, .063" gauge, 68 link, 18" chain. I recommend buying a decent chain brand -- Stihl, Husqvarna, or Oregon. Among these three, keeping the chain sharp will be more important than the chain's brand. I have the most experience with Stihl chains. They cut well and last a long time.

There are two primary Stihl chain models.
- RM (Rapid Micro) is their semi-chisel model. I recommend this for you. A semi-chisel chain cuts just slightly slower than a full-chisel chain, but it maintains sharpness noticeably better than a full-chisel chain. If you chain is likely to encounter non-wood stuff (dirt on the ground, dirt in the bark, etc.) definitely go with a semi-chisel chain.

- RS (Rapid Super) is their full-chisel model. This would still work for you, if you can't get a RM chain. The full-chisel really shows its capabilities for felling -- larger trees, or many trees at a time -- especially for a saw with with a larger engine. The cutting "point" of the full-chisel is a smaller than with a semi-chisel -- the saw cuts the wood really well as long as the chain is sharp.

Well, I don’t see any tree felling in my future… at least not for a few years. My use is really just cutting up firewood for ambiance fires.

Seems the Stihl chain is about $30 at my local Ace. I’ll have to grab one of those and a file.

3/16” file is correct for my chain?

Cutters Choice is a good place to buy chains and parts.

3/16" is the proper file for a .325 chain. This size file is included in the 2-in-1 device.

The 2-in-1 guide does the following things:
- Sharpens the teeth at the right angle.
- Sharpens the teeth at the right depth. This is accomplished by the guide rails.
- Files the rakers to the proper height, so the teeth cut at the proper depth in the wood.

If you have little experience filing a chain free-hand with a single file, you have good chance of seriously reducing the chain's cutting ability. Possibly even making the chain effectively unusable, until re-sharpened by a professional with a grinder.

Get a 2-in-1 file guide. Seriously.

Ordered. Thanks for the guidance!

Good call. I found it super easy to use the 2 in 1 and went out and cut some more wood, thanks to the city having taken down another diseased tree in my neighborhood. It cut much better than it had at the end of my last cutting session. Clearly this file should travel with the saw when doing any cutting.

Nice. Glad that it works for you. I pack the 2-in-1 file with the saws each time.

Don't worry about over filing -- just file so the teeth are sharp & true. Chains can last a long time and they're not all that expensive to replace.

Here's an old 3/8" chain on the old bar on my Stihl 310, with an almost-new chain above. Much of the steel on the teeth has been ground away on the old chain, but it cuts very well. The upper chain is a full chisel. The lower chain is an old semi-chisel, with bumpers. You likely won't see a chain like this anymore, as it's from the early 2000's. The bumpers have to be filed down occasionally just like the rakers, so filing can be slower. In theory, the bumpers reduce kick-back and make it harder to bore cut. But the bumpers make the saw very smooth when cutting rock-hard dead limbs -- no vibration and jumping.




Here's an old 3/8" Pico (low profile) chain on my EGO battery saw. I just retired the upper chain (off the saw), when 2 teeth broke off. The chain cut really well first thing that day, until the teeth broke. The lower chain (on the bar) is an almost new chain, and the teeth have much more steel.

It was warm here yesterday. This thread inspired me to get out the chainsaw and cut up some limbs from a tree cut down last fall. It took a couple of minutes to warm up and bogged down the first couple of times I hit the throttle, but after about 3 minutes it was fine.



"Some things are apparent. Where government moves in, community retreats, civil society disintegrates and our ability to control our own destiny atrophies. The result is: families under siege; war in the streets; unapologetic expropriation of property; the precipitous decline of the rule of law; the rapid rise of corruption; the loss of civility and the triumph of deceit. The result is a debased, debauched culture which finds moral depravity entertaining and virtue contemptible."
