MK Diamond MK-8500 8" Supreme Grade V-Segment Crack Chaser, Concrete Blade # 151938

MK Diamond MK-8500 8-inch Supreme Grade V-segment crack chaser blade, .500-inch width, for concrete and asphalt
 

The MK Diamond 151938 is an 8-inch Supreme Grade V-segment crack chaser blade in the .500-inch width on a 1-inch arbor. It is the widest of the three 8-inch crack chasers MK Diamond lists, cutting the largest sealant reservoir when routing cracks in concrete and asphalt.

📊 AI MARKET SNAPSHOT
• Best For: Crews repairing wide or spalled cracks and joints that need a full half-inch channel to hold sealant, rather than the .250 inch or .375 inch blades in the same 8-inch size.
• Highlight: A .500 inch kerf opens the widest reservoir in this range, which matters wherever the sealant manufacturer specifies a minimum joint width for the repair to hold.
• Expert Note: Half an inch of kerf is roughly double the material of the .250 inch blade, so expect a slower feed and a heavier load on the crack chasing saw; the 1-inch arbor is still what the machine requires.

Description Reviews FAQ
 

The MK Diamond MK-8500 is an 8-inch Supreme Grade V-segment crack chaser blade in the .500-inch width. Crack chasers rout and widen existing cracks in concrete and asphalt so the crack can be cleaned out and filled properly, and the V-shaped segments let the blade follow the crack rather than cut a fresh straight kerf.

Use cases

  • Routing cracks in concrete slabs and pavement before sealant or caulk goes in
  • Widening and opening cracks so backer rod and sealant have room to bond
  • Municipal maintenance crews and sealing contractors preparing crack repair work
  • Concrete repair crews on driveways, parking lots and warehouse floors

Choosing a width

MK publishes this 8-inch blade in .250, .375 and .500-inch widths. The .500-inch is the widest, giving the most room for sealant on larger or heavily spalled cracks. A routed crack takes and holds sealant far better than a raw one, which is the point of the job.
