The 125mm (5") Crack Chasing Diamond Blade is a specialised concrete repair tool engineered for routing, widening, and cleaning cracks prior to sealing, epoxy injection, or structural repair. Designed with a 10mm wide V-shaped diamond segment, this blade creates a consistent crack profile that promotes stronger bonding and longer-lasting repair results. Unlike standard cutting blades, the V-segment design allows the blade to follow irregular, curved, and wandering cracks with greater accuracy. This makes it ideal for concrete crack remediation, expansion joint preparation, decorative scoring, and surface restoration projects where precision is critical. Manufactured with high-quality diamond segments bonded to a durable steel core, the blade delivers fast cutting performance, excellent stability, and reduced vibration during operation. The robust construction helps minimise chipping while maintaining a clean cut profile across concrete, masonry, and asphalt surfaces. Suitable for both wet and dry cutting applications, this crack chasing blade is commonly used on driveways, warehouse floors, concrete slabs, footpaths, car parks, and commercial construction projects. Compatible with most 125mm angle grinders featuring a 22.23mm bore, it provides contractors with a reliable and efficient solution for professional crack preparation and repair work. Whether you're preparing cracks for polyurethane sealants, epoxy injection systems, or concrete fillers, this blade helps ensure a cleaner repair process and improved long-term performance.
