The STIHL 225mm Scratcher Tooth Circular Saw Blade is a professional-grade steel attachment designed for the most rigorous land-clearing applications. This powerful blade is ideal for cutting and clearing thick brush, woody vines, and established saplings. Its specialized scratcher-tooth profile provides a rugged, high-performance cutting action that excels in forestry and municipal maintenance where standard blades reach their limits.
Forged from premium-grade steel, this 225mm (8.9") blade is built for maximum durability and precision. Unlike chisel-tooth blades, this scratcher-tooth version is engineered to withstand extreme stress and must be sharpened by a professional to maintain its aggressive cutting geometry and factory balance. With a 20.0mm arbor, it is perfectly balanced for STIHL’s highest-capacity professional clearing saws.
Safety & Compatibility: This blade MUST be used with a brushcutter equipped with bicycle handles, a double shoulder harness, and the appropriate circular saw blade limit stop/guard. Approved for use with models: FS 361 C-EM, FS 461 C-EM, FSA 400 K, and FS 561 C-EM.
