Equipped with a high-output 20 HP engine running at 3600 RPM—featuring the renowned Honda GX630 in the gasoline concrete saw variant—this robust machine delivers exceptional torque and reliability for precise, deep cuts. The hydraulic concrete saw achieves a maximum cutting depth of 270 mm (with documented capability supporting up to 320 mm in optimised conditions), accommodating blades up to 800 mm diameter and incorporating an advanced hydraulic drive system with plunger pump, gerotor motor, and automatic feed functionality for smooth, controlled operation. A generous 25 L water tank provides superior dust suppression, enhancing workplace safety and blade longevity, while polyurethane wheels ensure damage-free movement across fresh concrete surfaces.
The Q800H is a robust hydraulic concrete saw designed for demanding construction environments, available in both gasoline concrete saw and diesel concrete saw variants to suit various operational needs. Powered by a reliable Honda GX630 engine in the gasoline version or an equivalent diesel engine, this epa concrete saw delivers exceptional performance with a maximum cutting depth of 270mm, making it ideal for precise and efficient concrete cutting. Featuring hydraulic drive for smooth operation, an 800mm blade capacity, and a generous 25L water tank to minimise dust and enhance blade longevity, the Q800H hydraulic concrete saw 320mm depth honda gx630 variant ensures versatility across medium to large-scale projects. Whether opting for the gasoline concrete saw 800mm blade 25l water tank model for quick starts or the diesel hydraulic concrete saw 270mm max depth for fuel efficiency, this concrete saw combines power, durability, and user-friendly features like automatic feed and comfortable grip handles for safe, professional results.
