Diablo segmented-rim diamond blade with the Speed-Edge slot pattern, engineered for dry or wet cutting of concrete, masonry, brick, block, pavers, and natural stone. The slotted rim sheds material and heat between segments for smoother, faster cuts and longer blade life on the abrasive material that masonry work throws at a blade.

• Diameter: 4"
• Construction: Segmented turbo rim with Speed-Edge slot design to reduce vibration
• Bond: Ultra-durable diamond-to-body bond for sustained cutting power and impact resistance
• Diamond exposure: Constant exposure design for consistent cut rate as the blade wears
• Cutting mode: Dry or wet
• Arbor: 7/8" with 20mm and 5/8" reducer bushings included
• Materials cut: Concrete, brick, concrete block, mortar, decorative concrete, pavers, natural stone, marble

Sized for 4-1/2" and 5" angle grinders, well suited to touch-up work, scoring tile and brick, trimming thinset and grout lines, cutting cement board, and quick masonry repair cuts.

Tip: Match the cutting mode to the material. Dry cutting is faster for short, intermittent cuts -- step off the trigger between cuts to let the blade cool. Wet cutting eliminates dust, controls heat on long continuous cuts, and extends blade life on hard aggregate concrete -- but only on saws rated for wet use. Always wear an N95 dust mask or run a HEPA-rated vacuum on dry masonry cuts to control respirable silica.
