STIHL TS 420 Gas Cut-Off Machine 14″ Concrete Saw 4.4 HP

Professional Cutting Performance for Construction and Infrastructure Projects

The STIHL TS 420 Professional Gas Cut-Off Machine has earned its reputation as one of the most reliable and versatile power cutters available for contractors, road crews, utility workers, landscapers, and construction professionals worldwide.

Designed to tackle demanding cutting tasks with precision and efficiency, the TS 420 combines a powerful 66.7cc gasoline engine producing 4.40 HP (3.20 kW) with a lightweight, ergonomic design that maximizes productivity while reducing operator fatigue.

Whether you’re cutting concrete, asphalt, reinforced concrete, masonry blocks, paving stones, steel pipes, metal profiles, rebar, or construction materials, the TS 420 delivers consistent power and dependable performance throughout the workday.

Its 14-inch cutting wheel capacity allows users to achieve cutting depths of up to 125 mm (4.9 inches), making it suitable for a wide variety of construction, demolition, landscaping, and municipal applications.

One of the TS 420’s most impressive advantages is STIHL’s revolutionary X2 Air Filtration System, which removes up to 99.96% of dust particles before they reach the engine. The cyclone pre-separation technology dramatically extends filter life, reduces maintenance requirements, and helps ensure maximum engine performance in dusty environments.

The STIHL Anti-Vibration System significantly reduces vibration transfer to the operator, resulting in improved comfort, greater cutting accuracy, and less fatigue during extended operation. Additional professional features such as IntelliCarb™ automatic fuel compensation, ElastoStart™ easy-start technology, semi-automatic belt tensioning, and integrated water connection further enhance productivity and reliability.

Built for professionals who demand performance, durability, and cutting precision, the STIHL TS 420 remains one of the most respected cut-off machines in the construction industry.
