RT-20T

The RUNTAI RT-20T is a Ø250mm metal-bond diamond grinding plate designed for concrete surface opening, coarse grinding, floor leveling, laitance removal, uneven-surface correction, old floor renovation, and scratch refinement after coarse grinding.

Its 20 T-shaped oval segments increase the effective contact area between the grinding plate and the floor, providing smoother machine operation and more uniform grinding patterns. It is suitable for medium and large floor grinding machines and delivers consistent cutting performance and high productivity in large-area applications.

The product is available in 20#, 30#, and 60# grits. Different bond types and hardness levels can be selected for soft, medium-hard, and hard concrete, ensuring continuous diamond exposure and a reliable balance between sharpness, wear resistance, and tool life.

Grit Applications

20#: Suitable for aggressive surface opening, heavy coarse grinding, correction of significant unevenness, and fast material removal.

30#: Suitable for general surface opening, laitance removal, coarse grinding of old floors, and initial floor leveling.

60#: Suitable for refining scratches after coarse grinding, surface correction, and transitional grinding before resin-pad applications.
