Bosch Segmented Diamond Blade DB564S 5 Inch Masonry Wheel (12250 RPM 7/8 Arbor 0.063 Kerf Wet Dry Reinforced Concrete Brick Stone Scoring Tool)

Bosch DB564S 5" Segmented Rim Diamond Blade for Reinforced Concrete & Masonry

The Bosch DB564S 5-inch segmented rim diamond blade cuts reinforced concrete slabs, slices structural masonry brick, trims hard natural stone pavers, and scores expansion joints without thermal blade warping. Rated for rotational speeds up to 12,250 RPM with a standard 7/8-inch arbor and an ultra-thin 0.063-inch blade kerf, this high-speed cutting disc mounts seamlessly onto small angle grinders, circular saws, and handheld cutoff tools for wet or dry operation. Featuring an industrial-grade synthetic diamond matrix across aerated cooling segment gullets and a tensioned alloy steel core that dampens vibration, it equips commercial masonry contractors, hardscape installers, and demolition crews with rapid cutting speeds and consistent tracking across dense structural substrates.

Best Used For:

• Reinforced Concrete Sectioning and Scoring: Slicing cured concrete slabs, precast walls, and foundation footings containing embedded wire mesh or light steel rebar.
• Hardscape Stone and Paver Fabrication: Trimming granite pavers, dense retaining wall blocks, slate tiles, and exterior fieldstone for tight landscape borders.
• Structural Brick and CMU Masonry Cuts: Sizing structural cinder blocks, clay face bricks, and mortar joints quickly on jobsites with handheld angle grinders.

Key Performance & Safety Features

• Segmented Air-Cooling Rim: Perimeter slots and deep expansion gullets maximize airflow to rapidly flush abrasive swarf and prevent thermal core distortion.
• Industrial-Grade Diamond Matrix: Precision diamond crystal distribution ensures consistent wear resistance and aggressive material removal in hard masonry.
• Tensioned Alloy Steel Core: Heavy-duty core plate eliminates rotational blade wobble, suppresses harmonic vibration, and ensures straight channel tracking.
• Ultra-Thin 0.063-Inch Kerf: Slim cutting profile minimizes dust generation, reduces motor drag on cordless power tools, and accelerates plunge speeds.
• 12,250 High-Speed RPM Rating: Built to withstand peak rotational velocities on industrial 5-inch angle grinders and high-speed masonry saws.
• Dual Wet and Dry Versatility: Operates efficiently dry with OSHA-compliant dust extraction shrouds or wet with water kits to control crystalline silica.

Technical Specifications

Pro-Tip: When cutting dense reinforced concrete or granite dry, allow the blade to reach its full 12,250 RPM before engaging the material and use smooth oscillating passes; this prevents heat buildup on the 0.063-inch kerf and keeps the diamond matrix open and sharp.
