RT-3X

The RUNTAI RT-3X is a three-segment, X-shaped metal-bond diamond grinding tool designed for concrete surface opening, coarse grinding, and surface preparation.

Its X-shaped segments provide strong cutting performance and high grinding efficiency. The tool is suitable for concrete surface opening, laitance removal, coarse floor leveling, scratch correction, and old concrete floor renovation.

The multiple cutting edges improve the speed at which the segments engage the floor while ensuring a smoother and more continuous grinding process.

The three-segment structure provides a reliable balance between cutting efficiency and operating stability. Compared with dual-segment tools, it delivers smoother operation. Compared with tools featuring more segments, it provides more concentrated pressure on each segment, achieving a good balance between sharpness, grinding efficiency, and service life.

Hard, medium, soft, and extra-soft bond options are available to match different concrete hardness levels. Selecting the appropriate bond allows the diamond particles to remain continuously exposed, making the RT-3X suitable for soft, medium-hard, and hard concrete floors.
