What Are Crack Chaser Blades? Crack chaser blades are specialized diamond blades designed to route and widen cracks in concrete or masonry for filling or sealing. These blades typically feature a V-shaped or inverted V segment, allowing them to dig deep into narrow crevices without damaging the surrounding material. The ROC Abrasives: Crack Chaser Blades take this functionality to the next level with high-quality materials, precision engineering, and a robust diamond matrix built for long-term use—even on the toughest jobsites. ROC Abrasives: A Leader in Diamond Blade Innovation Before diving deeper into the crack chaser blade itself, it's important to understand the brand behind it. ROC Abrasives has built a strong reputation for manufacturing premium-quality diamond tools that deliver consistent performance and extended life spans. Known for innovation, precision, and durability, ROC is a name that professionals trust for demanding cutting, grinding, and repair jobs. Key Features of ROC Abrasives Crack Chaser Blades 1. V-Groove Segment Design ROC's crack chaser blades feature a V-shaped groove segment, typically with widths of 1/4" to 3/8", which allows them to precisely follow narrow cracks in concrete. This geometry makes them ideal for routing cracks to prepare for filler or sealant. 2. High-Grade Diamond Matrix Each blade is made using a premium diamond matrix that ensures fast, clean cuts with minimal chipping. The high diamond concentration increases blade life and maintains performance even in abrasive materials. 3. Laser-Welded Segments The segments are laser-welded to a steel core, ensuring durability under high heat and stress. Laser welding also prevents segment loss during deep cuts, which is critical when working on structural or decorative concrete. 4. Universal Tool Compatibility ROC crack chaser blades come in common arbor sizes and are compatible with most handheld grinders, circular saws, and tuck point saws, making them easy to integrate into your existing toolkit. 5. Dry or Wet Cutting Capabilities These blades are suitable for both dry and wet cutting applications, giving contractors flexibility based on the work environment. Wet cutting helps reduce dust and blade wear, while dry cutting is more convenient for quick patch jobs.
