• Best For: Pavement and slab crews routing long crack runs on a 7-inch grinder, where the extra diameter reaches deeper than the 4-inch MK-404DV and covers ground faster.
• Highlight: Same .375-inch V-segment geometry as the smaller MK-404DV, but carried on a 7-inch plate that holds depth through wide, weathered cracks in asphalt.
• Expert Note: A 7-inch crack chaser needs a tool with the guard capacity and torque to match, so check the rating before stepping up from the 4-inch size, and run it dry as the segment is designed.
