STIHL GS 461 ROCK BOSS Concrete Chainsaw – 16"

The STIHL GS 461 ROCK BOSS® Concrete Chainsaw is a professional concrete cutter designed for deep cuts, precise corner cuts, wall openings, and demanding construction work. Powered by a 76.5 cc gas engine producing 5.8 bhp, the GS 461 uses a specialized STIHL diamond abrasive chain to cut concrete, reinforced concrete, masonry, cinder block, asphalt, and soft stone.

With cutting depth up to approximately 15.7 inches, the GS 461 gives contractors the ability to make deep cuts in a compact, maneuverable chain-based concrete cutter. Its integrated water connection supports wet cutting, while STIHL ElastoStart™, a decompression valve, anti-vibration system, HD2 filtration, and IntelliCarb™ help make demanding cutting work more manageable.

STIHL GS 461 Specifications

Professional STIHL Concrete Chainsaw

The STIHL GS 461 is different from a conventional wood-cutting chainsaw. It is a chain-based concrete cutter designed around a specialized diamond abrasive cutting system and integrated water supply.

This design allows the GS 461 to make deep, controlled cuts while retaining the maneuverability and cutting geometry of a chainsaw-style machine.

That makes it especially useful for jobs where a conventional circular cut-off saw cannot easily reach corners or achieve the required cutting depth.

What Can the STIHL GS 461 Cut?

The GS 461 ROCK BOSS is designed for professional cutting of materials including:

• Concrete
• Reinforced concrete
• Cinder block
• Masonry brick
• Asphalt
• Soft stone

The supplied product information also identifies reinforced concrete containing rebar up to approximately 1/2 inch as an application when using the correct STIHL cutting system and operating procedure.

Up to 15.7-Inch Cutting Depth

One of the biggest advantages of the GS 461 concrete chainsaw is its ability to cut approximately 15.7 inches deep.

That makes the ROCK BOSS useful for:

• Wall openings
• Deep concrete cuts
• Corner cuts
• Pipe and utility openings
• Masonry openings
• Construction and demolition work

Diamond Abrasive Cutting Chain

The GS 461 uses a specialized STIHL diamond abrasive chain rather than a conventional wood-cutting saw chain.

The cutting system is designed specifically for abrasive materials such as concrete and masonry.

When replacement cutting components are needed, match the chain and sprocket to the exact GS 461 bar and cutting-system configuration.

Wet Cutting With Integrated Water Connection

The GS 461 includes an integrated water connection with shut-off valve and quick connector.

Water is an important part of the GS 461 cutting system, supporting wet cutting of concrete and stone while helping manage dust and cool the cutting components.

Always follow the STIHL operating manual and applicable jobsite silica-dust and safety requirements.

STIHL ElastoStart™

STIHL ElastoStart™ uses a starter handle with an integrated shock-absorbing element designed to reduce the sudden forces transmitted to the operator during engine starting.

This helps smooth the compression forces normally felt through the starter rope.

Decompression Valve

The decompression valve temporarily reduces pressure in the combustion chamber during starting, helping reduce the pulling effort required to crank the engine.

HD2 Heavy-Duty Air Filter

Concrete and masonry cutting takes place in extremely dusty environments. The GS 461 uses an HD2 heavy-duty pleated air filter along with secondary filtration to support longer service intervals in demanding conditions.

The filter system is designed for convenient removal and service when maintenance is required.

IntelliCarb™ Compensating Carburetor

The IntelliCarb™ Compensating Carburetor is designed to help maintain an appropriate air/fuel ratio as the air filter becomes restricted.

As available airflow changes, the system compensates fuel delivery to help maintain engine operating performance.

STIHL Anti-Vibration System

The STIHL anti-vibration system helps reduce vibration transferred from the engine and cutting system to the operator.

This can improve comfort and cutting control during demanding professional concrete work.

Ergonomic Handle Design

The GS 461 features an ergonomic handle layout designed to provide a secure grip across different cutting positions.

This is especially useful during vertical cuts, corner work, and other applications where the machine may need to be repositioned frequently.

Rubber Bumper

A rubber bumper at the front of the engine housing helps protect the machine while it is positioned against material during cutting.

Bayonet-Style Fuel Cap

The fuel cap includes a retainer and is designed for straightforward operation, including when wearing work gloves.
