The V-Groove Crack Chaser is designed to route out and widen random existing cracks in cured concrete. Our high performing blade features heavy diamond concentration, allowing the operator to complete chip-free cutting quickly and smoothly.
Crack chasing is the process of cutting into the cracks in the concrete so that they can be waterproofed with a sealant or repaired with a filling compound like an epoxy. As its name states, the V-Groove Crack Chaser creates a V-shaped groove in order to simplify the repair process of re-caulking and re-filling.
This tool is very useful for commercial or residential jobs; repairing cracks found on driveways, roads, sidewalks, and building foundations.

How to Use:
- Make sure that you have chosen the proper blade for the application.
- Assure that the saw blade flange, shaft and guard are in good condition. Check your manufacturer’s user guide for safety precautions.
- Mount the blade in the proper rotation. Check for an arrow on the saw blade or look at the diamond segment to determine the direction. The diamond in the matrix appears as a “comet” with a diamond head and a “tail” following behind. The direction of the blade follows the “comet”.
- When cutting through a slab, make sure that you clear the blade from the cut before the slab shifts. If not, you could pinch the blade between the slabs immediately inhibiting the blade and possibly tearing away segments.
- To remove the blade, cut it free from the slab using another blade instead of pulling it out or risk bending the core.
Tips & Tricks:
Make sure that you vacuum and clear any dust that is left in the crack to prevent unwanted adhesion.
Never force the blade to cut, allow the weight of the saw be the cutting pressure. Always keep the RPMs of the saw constant.
Start by making a very shallow ½” cut to establish a base guide.
If the blade becomes dull, cut a concrete block to re-dress the blade.
Anything that is extremely abrasive or fine should be cut with a material specific blade.
