Concrete Joint Cutter - Ninja Joint Cleaning Blades

Concrete Joint Cutter - Ninja Joint Cleaning Blades

DIAMOND PRODUCTS SKU: 39999 Copied!

Is this the right tool for the job?

Best For:

  • Joint/crack seal crews doing daily control and expansion joint clean-out
  • One- to two-person crews crack chasing cured concrete on multi-site runs
  • Prep before reseal: debris/old sealant removal on medium-large runs

Not Ideal For:

  • Full-depth cuts or trenching; shallow joint clean-out only
  • Green concrete early-entry joints; use purpose-built blades
  • Indoor dry cuts without dust control; manage silica compliance

Why Pros choose this tool:

  • Application-matched concrete bond → stays sharp in cured joints → faster footage and fewer stalls on long runs
  • Narrow kerf joint-cleaning profile → consistent groove width → sealant seats right and passes inspection
  • 1 in. arbor joint cleaner fit → solid tracking in existing cuts → faster, cleaner long runs with fewer corrections

Product Details

This specialty diamond blade cleans narrow control joints and chases cracks in cured concrete for reseal and repair work. Professional joint seal crews, repair contractors, and owner-operators use it to open debris-filled joints cleanly without stepping up to full-depth cutting equipment.

  • Clean cured control joints before backer rod, sealant, or joint repair materials.
  • Chase slab cracks accurately for routing, filling, and repair preparation.
  • Maintain production on medium-size repair jobs with a purpose-built joint cleanout blade.
  • Limit unnecessary concrete removal compared with general-purpose cutting blades.
  • Use indoors or outdoors with appropriate saw setup and compliant silica dust control.

This blade suits joint clean-out and crack chasing only; use larger equipment for full-depth slab cuts or high-production roadway work.
