The MK Diamond MK-8250 is an 8-inch Supreme Grade V-segment crack chaser blade in the .250-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 .250-inch is the narrowest, removing the least material for hairline and smaller cracks. A routed crack takes and holds sealant far better than a raw one, which is the point of the job.
