CR450

Positioning: Precision crack chasing for clean, controlled repair channels.
Precision chasing: High-accuracy depth control follows the crack line, with precise width and depth, leaving a clean V-shaped or rectangular channel for repair material.
Crack-following: The blade tracks straight, curved, and irregular cracks, avoiding off-crack damage.
Low-vibration cutting: Optimized frame and vibration damping keep the cut steady — clean edges, no chipping, less hand chiseling before repair.
Ideal for: Designed for floor crack repair — clean, precise chasing improves repair quality and durability. A key tool in any crack repair process.
