STIHL 33RMF Rapid Micro Full Skip Chain
The STIHL 33RMF is a Rapid Micro full-skip chainsaw-chain configuration designed around a rounded cutter profile rather than a square-chisel cutter.
This makes the 33RMF a distinct chain family from STIHL square-chisel full-skip chains such as 33RSLF.
When ordering bulk chain, match the exact chain family rather than selecting solely by pitch and gauge.
3/8" Pitch
The STIHL 33RMF uses a 3/8-inch chain pitch.
Pitch must match the chainsaw's sprocket, guide-bar nose, and the rest of the cutting system.
.050" Gauge
The 33RMF uses a .050-inch drive-link gauge.
Gauge identifies the thickness of the drive-link portion that runs in the guide-bar groove. The guide bar and chain must use the same gauge.
Rapid Micro Rounded-Tooth Cutter
The supplied specifications identify the 33RMF as a Rapid Micro chain with a rounded-tooth cutter profile.
The cutter uses a 30° tooth angle.
This differentiates the 33RMF from square-chisel chain families and should be considered when choosing both the chain and the appropriate sharpening method.
Full-Skip Cutting Sequence
The 33RMF uses a full-skip sequence.
Full-skip chain has greater spacing between cutting teeth than a standard full-complement chain arrangement.
Always verify that the exact full-skip chain configuration is appropriate for the chainsaw, bar, sprocket, and cutting application before use.
1,640 Drive Links
The supplied reel specification lists 1,640 drive links.
Because this is bulk saw chain rather than one finished loop, individual chain loops must be measured and assembled to the exact drive-link count required by the specific guide-bar and chainsaw combination.

What File Size Does STIHL 33RMF Use?
The supplied specification for this STIHL 33RMF chain lists a 13/64-inch file.
Use the sharpening equipment and procedures specified for the exact 33RMF chain rather than assuming that another common chainsaw file size is correct.
Can I Use a 7/32" File on STIHL 33RMF?
The product information supplied for this 33RMF reel specifies a 13/64" file size.
For that reason, use the specified 13/64" sharpening setup unless STIHL's current technical documentation for your exact chain configuration instructs otherwise.
33RMF vs. 33RSLF
STIHL 33RMF and 33RSLF are different chain families.
| Chain | Cutter | Sequence |
|---|---|---|
| 33RMF | Rapid Micro / Rounded Tooth | Full Skip |
| 33RSLF | Square Chisel | Full Skip |
Even though both may use the same general 3/8" and .050" dimensions in the supplied configurations, they should not be treated as the same chain. Match the exact chain designation required for the application.
Yellow-Label STIHL Saw Chain
The supplied specification identifies 33RMF as a yellow-label chain with no safety link.
This is an important product characteristic. Operators should use the chain only with appropriate equipment, experience, safety procedures, and cutting-system specifications.
STIHL Oilomatic® Chain
The 33RMF incorporates STIHL's Oilomatic® chain design.
Correct lubrication remains essential for chain performance, guide-bar life, and cutting-system durability.
Bulk Reel vs. Ready-to-Install Chain
This product is a bulk chain reel, not a finished ready-to-install saw-chain loop.
| Bulk 33RMF Reel | Pre-Cut Chain Loop |
|---|---|
| Contains bulk saw chain | Already assembled into one loop |
| 1,640 drive links on supplied reel | Fixed drive-link count |
| Requires breaking and riveting | Ready to install when properly matched |
| Can produce multiple compatible loops | One finished chain |
