• Highlight: MK Diamond's MK-404DV V-segment profile is purpose-built to chase concrete cracks — the V-shape widens existing cracks into a uniform groove ready for epoxy or polyurea repair compound.
• Best For: Concrete repair contractors, parking-deck restoration crews, and floor coating installers prepping cracks for crack-fill epoxy or joint sealant.
• Expert Note: The 4" (102mm) V-segment blade runs on 4-1/2" angle grinders at ~10,000-12,000 RPM dry; light pressure and a steady pace keep the V-profile uniform along the crack length.
