STIHL 33RSLF Chainsaw Chain Reel
The STIHL 33RSLF is a professional bulk chainsaw-chain configuration intended for demanding cutting applications where a 3/8" pitch, .050" gauge, square-chisel, full-skip chain is required.
Buying the chain in a 100-foot reel allows a properly equipped shop or professional user to make individual chain loops to the exact drive-link count required for compatible saw and guide-bar combinations.
100-Foot STIHL Chainsaw Chain Reel
This listing is for a 100-foot reel rather than a pre-cut replacement chain loop.
The reel contains approximately 1,640 drive links.
Because it is bulk chain, the finished chain length is determined when the required number of drive links is measured, cut, and properly assembled into a loop.
3/8" Pitch
The STIHL 33RSLF uses a 3/8" (.375") chain pitch.
Pitch must match the chainsaw's drive sprocket, guide-bar nose sprocket, and overall cutting-system specification.
Do not select chainsaw chain based on bar length alone.
.050" / 1.3 mm Gauge
The drive links use a .050-inch / 1.3 mm gauge.
Gauge describes the thickness of the drive-link section that travels through the guide-bar groove. The chain gauge must match the guide bar.
Square-Chisel Cutters
The supplied specification identifies the STIHL 33RSLF as using square-chisel cutters.
This cutter design is intended for high-performance cutting and is typically selected by experienced and professional chainsaw users who prioritize aggressive cutting performance.
Full-Skip / Skiptooth Sequence
The 33RSLF uses a full-skip, or skiptooth, sequence.
A full-skip chain spaces cutting teeth farther apart than a standard full-complement arrangement.
This configuration is particularly relevant on longer guide bars and demanding cutting setups where the exact full-skip specification is required.
