Tianli Resin Bond Diamond Trapezoid Block:

Used in the mid-to-late stages of stone or floor grinding, transitioning from “fine leveling” to “glossing.” It relies on resin flexibility combined with diamond micro-cutting to remove scratches left by lower-grit tools (such as metal bond blocks), preparing the surface for final high-gloss polishing.

Compared to pure metal blocks, resin blocks offer better flexibility and self-sharpening properties, effectively preventing surface scorching and whitening while maintaining grinding efficiency.
