Lavina PCD the “3×1/2” signifies three segments, each half-round, designed for efficient coating removal, often paired with a diamond bar for stability, and comes in clockwise or counter-clockwise directions for different grinder head rotations.
Key Features & Function
Application: Primarily for removing thick floor coatings (epoxy, paint, glue, mastic, tar).
Design: Features three half-PCD segments, sometimes with a stabilizing diamond button, offering aggressive scraping and faster removal.
Compatibility: Fits Lavina floor grinders (X, S, Pro series) and other machines with compatible quick-lock systems.
Directional: Available in clockwise (CW) or counter-clockwise (CCW) for different grinder head rotations, important for balanced operation.
How it Works
The PCDs aggressively scrape off the coating.
The integrated diamond segment dresses the surface and helps guide the tool, preventing deep gouging.
It’s a two-in-one tool, removing heavy material and preparing the floor in one pass.
Usage Notes
Direction is crucial: Always match the tool’s rotation (CW/CCW) with your machine’s head rotation for safety and effectiveness.
