Choosing the Right Crack Chaser Blade for Concrete Repair
A crack chaser blade is an essential tool for cutting and widening cracks in cured concrete and masonry. Unlike general-purpose blades, crack chasers have a V-shaped segment profile that follows the natural path of a crack and opens it up for effective sealing. This makes them the go-to choice for structural and surface-level repair projects.
Typical Use Cases:
- Routing control joints in concrete
- Surface crack preparation before epoxy or sealant application
- Repair work on parking decks, garages, driveways, and sidewalks
- Resurfacing and refinishing concrete with embedded cracks
Blade Configurations and Sizes
Our crack chaser blades are available in multiple diameters—commonly 4″, 5″, 6″, and 7″. Smaller blades are ideal for handheld grinders, while larger ones suit walk-behind crack chasing saws for deeper cuts. All options are engineered to withstand the heat and abrasion of high-speed dry cutting.
Segment Design
The V-groove segment design helps center the blade in the crack and produces a clean channel for sealants to bond effectively. Premium blades may feature laser welding or specialized bond matrices to extend life on tough concrete surfaces.
Compatibility and Tools
- Fits most 5/8″ arbor angle grinders
- Works with high-RPM crack chasing saws
- Compatible with dust shrouds and vacuum attachments for cleaner job sites
Concrete Crack Chaser vs. Tuck Point Blade
While both blade types may look similar, crack chasers are optimized for routing cracks, whereas tuck point blades are meant for mortar removal. Using the right blade enhances cut quality and extends tool life.
Why Use a Dedicated Crack Chaser?
- Cleaner, straighter grooves than general diamond blades
- Reduces risk of wandering cuts
- Improves adhesion for fillers and joint sealants
- Cuts time and increases efficiency in concrete repair prep
