STIHL GS 461 ROCK BOSS Concrete Cutter 5.8 HP Diamond Chain Saw 16-18 Inch

The STIHL GS 461 ROCK BOSS® Concrete Cutter is a professional-grade gasoline-powered cutting machine engineered for deep, precise cutting in concrete, reinforced concrete, masonry, brick, asphalt, and stone. Powered by a high-performance 76.5cc engine producing 5.8 HP (4.3 kW), this rugged cutter delivers exceptional power while maintaining a lightweight and maneuverable design for demanding construction, demolition, and utility applications.

Unlike traditional cut-off saws, the GS 461 utilizes STIHL’s exclusive Diamond Abrasive Chain Technology, allowing operators to perform deep plunge cuts, square corner cuts, and wall openings with outstanding precision. Available with 16-inch and 18-inch guide bars, the machine can achieve cutting depths of up to 15.7 inches, making it ideal for structural modifications, utility access work, concrete pipe cutting, and heavy-duty demolition projects.

Built for professional use, the GS 461 features a long-life HD2 air filtration system that provides superior protection against dust and debris while extending maintenance intervals. The integrated water supply system with quick-connect fitting and shut-off valve helps suppress dust and cool the cutting chain during operation, improving both cutting performance and jobsite safety.

Operator comfort is enhanced through the STIHL Anti-Vibration System, ergonomic top-handle design, ElastoStart™ starter handle, and decompression valve, all working together to reduce fatigue and simplify starting. Whether cutting reinforced concrete, masonry blocks, stone, or asphalt, the GS 461 ROCK BOSS® delivers professional-grade performance, exceptional durability, and industry-leading cutting capability.
