The MK Diamond MK-404DV 4-inch crack chaser (part 156048) is a supreme grade blade for hand-held grinders. Its V-shaped segments are designed to quickly route and widen cracks in concrete and asphalt, giving sealant and repair material a clean channel to bond in.
MK Diamond says the long-lasting, dry cutting design is used to cut down on resealing time. It is laser welded, with a 13mm segment height and a .375-inch width.

Fit and compatibility
This blade is made for hand-held grinders. Confirm that your grinder accepts a 4-inch blade and a 7/8-5/8 arbor and that the guard fits. MK Diamond also lists this model with a 5/8-11 arbor under other part numbers, so check the arbor before you order.
Getting the most from the blade
This is a dry-use blade. Keep the guard in place, let the blade cut rather than forcing it, and wear eye, hearing and respiratory protection, since cutting concrete and asphalt creates dust. Follow your grinder maker's safety guidance.
