STIHL Chain ID Reference

STIHL posted a link on Facebook to a guide to how their chains are numbered.

33RS
3/8 pitch, .050 gage , Rapid, Full Chisel.
Good chisel chain

No other numbers, not a safety or low kick back chain. ;
comes with a yellow link & a safety warning.

RS3 with the humped drive links to reduce kickback is what they are pushing for non professionals.
Green mark, Low kickback

It's in their full-line product catalog (what, you don't have one?! ) and the Bar And Chain catalog available via their website's Interactive Catalog section. I'd love to see one that included discontinued lines as well.

Actually it get's much deeper than this.

Available in .325, 3/8", and .404 (not every type is available in all 3 pitches/gauges)

RS/RSC = Chisel chain (aka. Full-chisel), yellow label
RS3/RSC3 = Chisel chain, low-kickback, green label

RM/RMC = Semi-chisel (similar to but not the same as "chipper chain" chain although the term is often used interchangeably), yellow label
RM3/RMC3 = Semi-chisel chain, low-kickback, green label

RD = Carbide chain
RDR = Rescue chain, which is basically RD chain with the RM2 () tie straps.

And that's just the bigger stuff. Then you have the Picco series, with similar nomenclature.

PM/PMC was yellow label Picco (3/8" Low-Profile) chain that was freakin' excellent stuff for small saws. I hear that it is no longer in production.

PMMC3/PMM3 = .043 guage narrow kerf semi-chisel low-kickback chain usually found on Stihl saws under 35cc.

PM3/PMC3 = is the current semi-chisel, green label, low kickback chain that comes on most Stihl saws under 40cc .

PS3 = relatively new, chisel chain, albiet green label, low kickback. Really wish I had a saw setup for Picco chain, want to try this stuff. C'mon Stihl, give us a yellow label version of this stuff, PLEASE????

and I'm not going to touch the semi-skip, full-skip, square ground, or Klassic stuff.

"Yeah uh, lemme get a 33RSLHK-105 and two 33RS-72's please."

"Would you like fries with that sir?"

I was lucky to snag 3 loops of 63PM55 off ebay for the 191T last week, $34 shipped. It was the last 3 loops off a guys old 100' roll! And it came with onion rings too!

If you can be a bit more specific about what you're looking for, I may have it.

That's just it, I'm not looking for anything specific.

I can forward the file I have if you'd like on Monday when I get back to work.

That would be fantastic, Thanks!
