Handles like a chainsaw, but with the power of a cut-off machine: the GS 461 concrete saw from STIHL. It's ideal for cutting concrete, masonry, concrete pipes and ductile cast iron pipes. But what really makes it stand out from the crowd is its impressive cutting depth, great power-to-weight ratio and ability to cut precise corners. The guide bar perfectly matches the tool and features nozzles that point forward for effectively supplying the chain with water. And the special diamond saw chain transforms the engine power into superior cutting performance.

STIHL MotoMix® is our patented premixed fuel, specially blended for ultimate performance. Like a sports drink for your engine, this 50:1 mixture is a combination of premium non-ethanol, high-octane motor fuel and our highest-quality STIHL HP Ultra oil. Clean and convenient, MotoMix® eliminates the hassle of mixing your own 2-stroke engine fuel while providing superior performance and lubrication. Plus, we stand behind this formulation by doubling the limited warranty when you include MotoMix® with your power tool purchase. STIHL MotoMix® contains no ethanol, allowing it to maintain stability for up to two years after the seal is broken - so it stays fresh in your equipment during long storage periods. MotoMix® is also made of non-aromatic fuel and fully synthetic, highly biodegradable engine oil. It’s no surprise that MotoMix® is the official fuel of the STIHL® TIMBERSPORTS® Series.
STIHL Diamond Abrasive Chain 36 GBM
The STIHL Diamond Abrasive Chain 36 GBM is the first of its kind ever offered by STIHL. This chain features a pre-sharpened diamond segment on each link, making it immediately ready for cutting concrete and stone. It’s designed to deliver high cutting speed, smooth cuts and good performance during plunge cuts. The diamond segments reduce vibration, improving overall cutting speed. A depth gauge between each diamond segment improves chain ruggedness and plunge cut performance. The chain also features a “sandwich” segment design for faster cutting and longer service life. Expected service life is approximately 40-80 linear feet of cutting in 6-inch thick concrete (chain life will vary greatly depending on aggregates and steel reinforcement).
Applications: This chain is to be used exclusively with the GS 461 STIHL Rock Boss® concrete cutter and the STIHL ROLLOMATIC® G guide bar. The chain is designed to cut concrete, reinforced concrete (with rebar up to ½ inch), cinder blocks and masonry (including bricks, asphalt and soft stone such as sandstone). Cutting hard stone such as granite and ductile iron pipe are also approved applications but will reduce the service life of the chain.
STIHL ROLLOMATIC® G Guide Bar
Based on STIHL’s many years of experience designing guide bars and chains, the STIHL ROLLOMATIC® G is a 16-inch guide bar that is designed for the professional application of concrete and stone cutting. The bar requires no bar oil – it uses water and features internal water channels that are directed toward the cutting area. This delivers optimal cooling and debris flushing of the chain and sprocket nose. The bar also features an additional tensioning hole to further increase chain tensioner travel. The expected service life of the STIHL ROLLOMATIC® G guide bar is equal to the service life to 2-3 STIHL Diamond Abrasive 36 GBM chains.
Applications: This guide bar is to be used exclusively with the GS 461 STIHL Rock Boss® concrete cutter and the STIHL Diamond Abrasive Chain 36 GBM; this guide bar is NOT to be used with any other STIHL products, including chain saws. The bar is designed to cut concrete, reinforced concrete (with rebar up to ½ inch), cinder blocks and masonry (including bricks, asphalt and soft stone such as sandstone).
