• Highlight: MK Diamond MK-925DSLX supreme grade 20" blade designed for concrete block — segmented rim with soft-bond matrix tuned for the abrasive sand-aggregate mix in CMU.
• Best For: Masonry crews and block layers running 20" handheld and walk-behind saws on cured concrete block, brick and similar abrasive aggregate.
• Expert Note: 20" x .145" x 1" arbor in a supreme grade designation; the soft-bond matrix is correct for concrete block but will wear faster on cured slab where a DX-10 grade fits better.
