RT-4H

The RUNTAI 4H is a four-segment, curved metal-bond diamond grinding tool designed for coarse grinding and concrete surface preparation.

It is suitable for concrete surface opening, coarse floor leveling, laitance removal, scratch correction, and old concrete floor renovation.

The H-shaped curved segments provide smooth floor engagement, stable operation, and uniform grinding patterns. The four-segment design increases the contact area with the floor and helps reduce machine vibration, making it suitable for grinding applications that require improved stability and surface consistency.

The product is available in 16#, 30#, and 60# grits. The 16# grit is suitable for aggressive surface opening, correcting significant floor unevenness, and heavy coarse grinding. The 30# grit is designed for general surface opening, laitance removal, and initial floor leveling. The 60# grit is suitable for refining coarse scratches and transitional grinding before resin polishing.

Hard, medium, soft, and extra-soft bond options are available for different concrete hardness levels, providing a reliable balance between cutting performance, wear resistance, and service life.
