HTG GX250 – 250mm Variable Speed Concrete Floor Grinder – Single Phase

Take your floor grinding results to the next level with the GX250 — a compact, high-efficiency planetary grinder engineered for contractors who demand maximum productivity on a standard single-phase supply.

Key Features

• High-Efficiency Permanent Magnet Motor – The GX250 utilises a permanent magnet synchronous motor combined with advanced vector control algorithms. It starts easily even with voltages as low as 200 V and maintains a steady grinding current within just 5 amps, significantly outperforming older models.

• Low Start Current (<10 A) – Thanks to its built-in large capacitor charging and motor design, the machine starts smoothly even under load (for example when an operator stands on it), reducing stress on site power systems

• Versatile Tool Compatibility – Compatible with a wide variety of tooling including diamond pads, resin pads, cup wheels and bush hammers—making it suitable for everything from aggressive removal to final polish.

• Specifications

  • Motor Power: 1.1 kW / 1.5 HP

  • Working Width: 250 mm

  • Voltage: 110 V / 220 V (model-dependent)

  • Rotational Speed: 350-1500 rpm

  • Weight: Approx. 60 kg

  • Machine Dimensions: 833 × 355 × 1,161 mm

Why Choose the GX250?

• Optimised for small to medium residential and commercial projects where three-phase power may not be available.

• Reduced energy draw and steady power delivery make it ideal for sites with limited or unstable voltage.

• The tooling flexibility allows you to cover removal, grinding, honing and polishing with one machine.

• Built to last with robust construction and modern motor technology for high uptime and low maintenance.

Typical Applications

• Concrete surface preparation in apartments, retail fit-outs and light commercial buildings.

• Removal of coatings, adhesives and toppings prior to floor refinishing.

• Pre-polish grinding and honing where a compact, efficient machine is needed.

• Finish work in low-access or power-limited environments.

Package & Options

The GX250 is supplied with standard planetary drive and tooling interface. Optional accessories such as vacuum shrouds, dust-control systems, and different tool plates can be added according to your application.
