Dual-Row Segment Matrix:
The inner row aggressively tears through high spots and coatings, while the outer row refines and levels the surface. This dual-action design significantly reduces operator fatigue and prevents deep scratching, leaving a perfectly prepped, smooth substrate.

Optimized Slurry & Dust Evacuation:
The precision-punched steel body reduces overall weight while creating aerodynamic channels. When paired with a dust shroud, it maximizes vacuum dust extraction and dramatically improves heat dissipation, preventing bond glazing during intensive dry grinding.
