Step up to heavy-duty commercial cutting without the noise, exhaust fumes, or maintenance of gas engines with the STIHL TSA 300 Cordless Battery-Powered Cut-Off Machine. Part of the elite STIHL AP Pro battery series, this compact and lightweight powerhouse is specifically designed to cut deeper than a traditional 12-inch TS 410 gas saw. With zero exhaust emissions and incredibly low-noise operation, the TSA 300 is the premier choice for professionals executing deep indoor slab breaching, basement utility trenching, and masonry work inside confined or unventilated jobsites.
The engineering heart of the TSA 300 is a high-performance, wear-free brushless commercial motor managed by an advanced electronic control system that maintains peak power output across the entire battery charge lifecycle. To maximize field runtime, the saw features a smart fast-stop brake with a recuperation function. When the trigger is released, the blade stops within seconds, converting kinetic energy into electrical power and feeding it directly back into the battery. It is also outfitted with an advanced STIHL magnetic filter system that safely traps harmful ferrous dust and metallic shavings away from core electronics, drastically extending the service life of the machine during high-volume steel cutting.
Advanced Dust Suppression & Precision Control: Fully rated for heavy wet-cutting production, the TSA 300 features an integrated water connection with a smart quick-connect hose adapter that automatically shuts off the water flow the moment the hose is detached to prevent site pooling. Combined with a responsive variable-speed trigger for delicate feathering and structural precision, this tool provides civil contractors, landscape crews, and rescue squads with unparalleled control. The rugged, splashproof IPX4 construction ensures reliable operation in driving rain and adverse weather conditions.
Power & Digital Integration Note: Features built-in compatibility for the Smart Connector 2A to easily integrate into the digital STIHL connected fleet management platform. Run time varies based on battery type, material density, and operator technique. Powerhead only; AP-Series batteries and chargers are sold separately.
Key Features & Benefits
- Deeper Cutting Capacity: Achieves a maximum cutting depth of 4.3 inches (110 mm), out-cutting standard 12" gas-powered saws like the TS 410.
- Zero-Emission Indoor Utility: Operates clean with no exhaust fumes, making it ideal for indoor masonry, basement conversions, and deep trenching work.
- Energy Recuperation Brake System: High-speed blade brake stops the wheel in seconds while feeding reclaimed kinetic energy back into your battery pack.
- Advanced Magnetic Particle Filter: Captures magnetic steel filings and dust out of the cooling air stream to protect internal components during heavy metal demolition.
- Smart Quick-Connect Water Controls: Automatic water-stop valve shuts off flow instantly upon hose disconnection to minimize jobsite mess.
- IPX4 Splashproof Certification: Built to endure demanding professional field use, fully certified to operate reliably in pouring rain and wet environments.
- Variable-Speed Trigger: Delivers precise throttle modulation and smooth power engagement for starting straight, accurate cut lines.
