The Stihl 33RS 72 is a high-performance chainsaw chain designed for the most demanding cutting conditions. This chain is part of the Stihl Rapid Super series, known for its fast cutting and efficient performance. It is ideal for professional use, particularly in applications such as felling, bucking, and limbing.

The 33RS chain features Oilomatic drive link lubrication, which funnels oil directly to the rivet to reduce wear and extend the chain's life. It is also pre-stretched at the factory to eliminate excess adjustments during the break-in period.

Key Features

• Fast Cutting Efficiency: The 33RS chain is an aggressive, full-chisel chain that ensures minimum chain friction for exceptionally smooth and clean cuts in hard or frozen wood.
• Reduced Vibration: The chain is designed with a single-humped drive link and a cutter and tie strap design to reduce vibration levels during cutting.
• Low Kickback Tendency: Although it is a fast-cutting chain, it has features to reduce kickback, making it safer for professional use.
• Professional Grade: Best suited for medium to high-powered chainsaws, this chain is ideal for full-time professionals who require high-performance cutting tools.
• Oilomatic Lubrication: This feature ensures that the chain is well-lubricated, reducing wear and extending its lifespan.
• Pre-Stretched: Pre-stretching at the factory eliminates the need for frequent adjustments during the break-in period.
