About This Product
1900W Concrete Grinder for Surface Preparation
The BIHUI® CG1900A 7" Concrete Grinder is a 1,900W handheld concrete floor grinder designed to remove old coatings and prepare surfaces for renovation. Its adjustable speed ranges from 0 to 3,000 RPM, and it accepts most 7" (180mm) diamond or resin cup wheels for grinding concrete, natural stone, tile, tile adhesive, plaster, paint, coatings, and carpet adhesive.
Corner and Inner-Edge Grinding
A magnetic removable front cover provides access for grinding along corners and inner edges where an enclosed grinding head would limit reach. The ergonomic design supports balanced handling, while the aluminum alloy, steel, and high-strength engineering nylon construction provides durability for surface preparation work.
Vacuum-Compatible Dust Collection
The self-cleaning design includes a professional vacuum port that can be connected to a dust bag or compatible vacuum system. Collecting grinding debris at the source supports cleaner, dust-controlled operation during coating removal and concrete floor preparation.
Soft Start and Motor Protection
Full-wave electronics, soft start, and start-current limiting provide a smoother, more controlled startup. Adjustable speed control allows the grinder to be matched to the application, while overload and power-off protection help protect the tool during demanding grinding work.
