STIHL 33RS3-66 Oilomatic® Rapid Super 3 Chain delivers exceptional cutting performance combined with enhanced safety features. Designed with a single-humped drive link to reduce kickback and a specialized cutter and tie strap configuration, this chain minimizes vibration while maintaining an aggressive, fast-cutting full-chisel design. The razor-edged, square-cornered cutters reduce chain friction, enabling smooth and clean cuts even in hard or frozen wood. Renowned for its cutting and plunge-cutting efficiency, the RS3 chain surpasses the RM chain in cutting speed but requires regular sharpening and maintenance to sustain its high performance. I for medium to high-powered chainsaws, this chain excels in felling, bucking, and limbing applications. Designed for professional use, it strikes a balance between performance and safety, making it a reliable choice for demanding tasks. For optimal safety, STIHL recommends pairing low-kickback, green-labeled chains with reduced-kickback bars on all powerheads. Model Number: 33RS3 66
