SURTEC Brush Cutter NTB330B
Industrial OEM Gasoline Chainsaw with 16-20 Inch Guide Bar
The SURTEC NT4510 is an industrial OEM gasoline chainsaw engineered to deliver precision and dependable power in a compact, balanced frame. Its 45cc two-stroke, air-cooled engine produces 1.7KW of rated power at 7500rpm, providing steady, controllable output for medium-sized wood, garden maintenance, and everyday farm and logging work. With guide bar options from 16 to 20 inches, the NT4510 bridges the gap between lightweight homeowner saws and full-size felling machines — making it a versatile wood cutting chainsaw for operators who regularly move between limbing, bucking, and small-to-medium tree work.
Performance is driven by smart engineering. The brand-new air-filter system uses vortex airflow to spin out heavy dust particles before they reach the engine, extending filter life and keeping peak efficiency on long jobs. A direct-air injection carburetor ensures complete combustion for efficient fuel burn, translating into stable power delivery, better fuel economy, and lower emissions. The result is a machine built for endurance: the NT4510 can run for over 200 hours of continuous operation without compromising performance, a durability benchmark that professional and semi-professional users genuinely rely on.
Handling and operator comfort have not been overlooked. The balanced frame makes the saw easy to control and noticeably reduces strain, while the anti-slip ergonomic handle provides a high-friction, stable grip for precise work. Effective vibration-reduction dampers lower hand-arm fatigue during extended cutting, and the convenient fuel structure — a transparent fuel window paired with a quick flip-up cap — keeps refills fast and level checks instant. Component quality reinforces the whole package: a precision-forged lightweight aluminum engine body, heat-resistant reinforced nylon fittings that resist aging, a German-standard alloy saw chain that stays sharp, flexible, and break-resistant, a wear-resistant alloy guide bar for continuous cutting, and a CE-certified safety brake that meets European standards for sensitive, reliable stopping power.
For the trade, the NT4510 is both a complete chainsaw and a parts platform. Designed for household and light commercial cutting, it is supported by a full line of CE-certified, high-strength spare parts made from premium aluminum alloy and reinforced nylon — perfectly matched to the 16–20 inch machine and ideal for global B2B wholesalers and hardware distributors who want balanced durability, comfort, and great cost performance. As an OEM favorite among chainsaw dealers, chainsaw manufacturers, and outdoor power equipment distributors worldwide, the NT4510 enjoys steady demand across Latin America, Africa, Eastern Europe, and Southeast Asia. For importers and distributors seeking a mid-range industrial chainsaw that sells reliably and supports a profitable spare-parts business, the SURTEC NT4510 is a dependable choice.
