Stihl GS461 Rock Boss General Purpose Diamond Chain - 36GMB

When heavy demolition demands surgical precision and immense depth, reach for the undisputed authority: the STIHL GS 461 ROCK BOSS® Concrete Cutter. This revolutionary gas-powered concrete chainsaw completely changes the game on commercial construction sites, allowing operators to make plunge cuts, square corners, and pocket cuts up to an incredible 15.7 inches deep. It cuts cleanly through reinforced concrete (with rebar up to 1/2-inch), cinder blocks, structural masonry bricks, asphalt, and soft stone, all while maintaining a compact, lightweight profile that is highly maneuverable in tight trenches or confined workspaces.

Built to withstand the absolute harshest structural cutting environments, the GS 461 ROCK BOSS® features an specialized onboard water management system. This advanced control module feeds water directly into the guide bar groove, cooling the chain, flushing out highly abrasive slurry, and suppressing airborne crystalline silica dust to ensure strict jobsite compliance. Its high-torque engine is paired with a heavy-duty, long-life HD2 air filter system that bars fine concrete dust from entering the powerhead, drastically extending your operational runtime between service intervals.

Elite Engineering & Handling: Because it’s a specialized STIHL® commercial tool, user comfort and machine life are paramount. The ROCK BOSS® utilizes an advanced multi-point anti-vibration system that isolates intense engine and cutting vibrations away from the handle bars, minimizing operator fatigue during prolonged vertical or horizontal wall cuts. The tool comes optimized with a durable, rubber-armored hand guard, a specialized chain sprocket side cover with integrated water deflection, and a professional-grade diamond abrasive chain designed to track flawlessly through thick aggregate materials.

Please Note: (1) Heavy-duty 16-inch Rollomatic® G Guide Bar and (1) Premium Diamond Abrasive Cutting Chain are included out of the box. Replacement chains and water hoses are sold separately.

Key Features & Benefits

• Unmatched 15.7-Inch Plunge Depth: Specialized long-reach bar layout allows you to cut deep structural walls, square openings, and utility pipe tracks from a single side without over-cutting corners.
• Reinforced Concrete & Rebar Capable: Specifically engineered to slice directly through embedded steel rebar up to 0.5 inches in diameter without binding or chain failure.
• Advanced Dust & Slurry Suppression: Integrated water connection feeds internal channels within the guide bar, continuously lubricating the diamond segments and trapping fine aggregate dust.
• Heavy-Duty HD2 Filter System: Washable polyethylene filter cartridge features radial pores that trap fine stone particulates, protecting the engine and maintaining peak horsepower.
• Professional Anti-Vibration Layout: Strategically positioned rubber-and-spring dampeners decouple the powerhead from the operator grips to ensure precise control and reduced physical strain.
• Exclusive STIHL Diamond Chain Technology: Features pre-stretched, laser-welded diamond abrasive segments on every drive link for exceptionally fast cutting speeds and rugged structural life.
• Decompression Valve & ElastoStart™: Drastically reduces compression resistance when pulling the starter cord, allowing for quick, reliable hot-starts in deep trenches.
