The GS 461 ROCK BOSS® is a heavy-duty, professional-grade gas concrete cutter designed for deep, precise cuts in concrete, masonry, asphalt, and soft stone — making it ideal for infrastructure work, station maintenance or construction jobs where durability and power are essential.

Key Features & Benefits

• Deep-cutting power: Capable of cutting up to 15.7" deep into concrete, reinforced concrete (including rebar up to ½"), cinder blocks, masonry bricks, asphalt and soft stone — powerful enough for wall penetrations, trenching, or heavy renovation work. 

• Professional-grade engine performance: Powered by a 76.5 cc, 4.3 kW (5.8 bhp) gas engine with advanced low-emission 2-MIX technology for strong torque and efficient fuel consumption. 

• Efficient water-cooled wet cutting: Includes a water connection and internally flushed guide bar to keep dust levels down and cool the diamond chain during cutting — especially important when working in dusty or enclosed environments.

• Operator-friendly ergonomics: A compact, relatively lightweight powerhead (~16.8 lbs / 7.6 kg) offers a favorable power-to-weight ratio, making the cutter easier to handle, maneuver, and transport on job sites.

• Reduced vibration & easier use: Built-in anti-vibration system helps reduce operator fatigue during extended jobs, while features like a side-mounted chain tensioning system, tool-free fuel cap, and ergonomic top-handle grip make maintenance and use simpler and more comfortable.

• Long-lasting, heavy-duty build: Equipped with a durable diamond abrasive chain (type 36 GBM) and a guide bar specifically engineered for concrete and masonry cutting for reliable, consistent performance under tough conditions.
