The CONSMAC SC450 walk-behind concrete saw is purpose-built for heavy-duty pavement cutting operations on asphalt surfaces, reinforced concrete slabs, and composite pavement structures. It serves as a versatile asset for highway maintenance crews, municipal public works departments, and commercial flooring contractors.

Power is supplied by a 13.0HP (9.6kW) Honda GX390 four-stroke engine—a globally recognized powerplant known for reliable starting, consistent torque delivery, and excellent fuel economy under sustained load. The engine drives 400-450mm diameter diamond blades at a no-load speed of 2880rpm, generating a blade tip speed of approximately 67.8m/s—placing cutting operations within the optimal linear velocity range for diamond tooling that balances rapid material removal with acceptable blade wear rates. The 25.4mm (1.0 inch) arbor conforms to international industry standards, ensuring broad compatibility with aftermarket diamond blades from multiple manufacturers.

The machine achieves a maximum cutting depth of 170mm in a single pass, enabling operators to cut through full-depth pavement sections for complete slab removal, deep contraction joints, and clean vertical edges for asphalt patching. The depth adjustment mechanism employs a manual screw-jack system providing precise, repeatable settings with minimal effort—particularly valuable when transitioning between shallow joint cutting and deep slab demolition. This single-pass capability eliminates the time penalties of multi-pass stepped cutting, directly translating to faster project completion and reduced fuel consumption.

Thermal management is addressed through a centrifugal water injection system. During operation, cooling water is fed through the blade arbor and distributed outward by centrifugal force, ensuring complete coverage of the cutting zone—delivering superior cooling efficiency compared to conventional external spray bars. The 35-liter reservoir supports extended cutting cycles without frequent refills, while wet cutting effectively captures airborne silica particles, addressing worker health concerns and regulatory compliance.

Weighing 120kg with a carefully engineered low center of gravity, the SC450 maintains excellent stability during deep cuts, minimizing operator-induced deviation and ensuring straight, true cuts. The compact 94×57×109cm footprint allows easy transport in standard vehicle beds and maneuverability in confined work areas. The saw features a lift-up front blade guard for tool-free blade access and rapid changeovers, while the blade spindle utilizes premium sealed bearings for extended service life. A robust belt tensioning system reduces maintenance frequency and operational downtime.

The SC450 is configurable with multiple engine options: the Honda GX390 (13.0HP/9.5kW) remains the standard choice for its proven reliability and parts availability. CE certification confirms compliance with European safety and environmental standards. Each unit is accompanied by a mechanical test report and factory video inspection record, providing documented performance verification prior to shipment. Core components are covered by a 1-year warranty. Manufactured in Zhejiang, China.
