Bosch Segmented Diamond Blade DB541H 5 Inch Masonry Wheel (1-1/2 Inch Cut Depth 7/8 Arbor Wet Dry Laser Weld Concrete Brick Block Hardscape)

Bosch DB541H 5" Premium Laser-Welded Segmented Rim Diamond Masonry Blade

The Bosch DB541H 5-inch segmented rim diamond blade cuts cured concrete slabs, slices structural cinder block, trims clay brick pavers, and scores hardscape masonry up to a 1-1/2-inch cutting depth without thermal degradation. Engineered with a multi-fit 7/8-inch arbor including 20 mm and 5/8-inch reducing bushings, a narrow 0.080-inch segment kerf, and a tensioned alloy steel core, this high-speed wheel delivers 20% faster feed rates on small angle grinders and compact masonry saws. Featuring laser-welded cutting segments embedded with deep industrial diamond distribution and cooling gullets for rapid debris extraction, it provides masonry contractors, hardscape installers, and general remodelers with aggressive cutting speed and extended wheel life during demanding wet and dry jobsite cutting operations.

Best Used For:

• Concrete Slab and Footing Sectioning: Slicing cured concrete, precast steps, and foundation footings up to 1-1/2 inches deep for utility trenching and expansion joint repair.
• Brick and Cinder Block Sizing: Trimming structural CMU blocks, standard red clay masonry bricks, and retaining wall units quickly to custom dimensions on site.
• Hardscape and Paver Installation: Cutting dense interlocking concrete patio pavers, stone edging, and landscape borders with angle grinders for tight boundary fits.

Key Performance & Safety Features

• Laser-Welded Segment Technology: Single-step laser fusion permanently welds diamond segments to the steel core, providing exceptional joint integrity under high friction.
• Deep Diamond Matrix Distribution: Premium industrial synthetic diamond crystals are distributed uniformly through the segment depth to ensure consistent cutting speed.
• Segmented Air-Cooling Rim: Perimeter slots and deep expansion gullets maximize airflow to rapidly flush swarf and prevent thermal core distortion.
• 0.080-Inch Narrow Kerf: Thin cutting profile minimizes dust output, reduces motor strain on cordless power tools, and increases plunge cutting speeds.
• Multi-Arbor Mounting Versatility: Direct 7/8-inch bore includes precision brass reducing rings to fit 20 mm and 5/8-inch grinder spindles and cutoff tools.
• Dual Wet and Dry Operation: Optimized for dry cutting with dust collection shrouds or wet cutting with water delivery attachments to suppress airborne crystalline silica.

Technical Specifications

Pro-Tip: When dry cutting hard aggregate concrete or dense retaining wall block, let the grinder's speed and the blade weight drive the cut without applying excessive downward force; allowing the air-cooling gullets to clear debris prevents segment overheating and core warpage.
