Bosch Diamond Blade DB542H 5 Inch Turbo Rim (13300 RPM 1-1/2 Inch Cut Depth Concrete Brick Masonry Angle Grinder Cutting Tool)

Bosch DB542H 5-Inch Premium Diamond Turbo Rim Circular Saw Blade

The Bosch DB542H 5-Inch Diamond Turbo Rim Blade provides fast, smooth dry cutting across reinforced concrete, hard clay brick, concrete masonry units (CMU), and natural stone up to a maximum cutting depth of 1-1/2 inches (1.50 in). Formulated with industrial-grade diamond grit embedded in an optimized metal matrix, this 0.075-inch thick blade operates safely at rotational speeds up to 13,300 RPM. A multi-fit arbor system with 7/8-inch, 20mm (0.787 in), and 5/8-inch bushings mounts directly onto corded and cordless small angle grinders to deliver rapid, low-friction aggregate slicing on demanding commercial jobsites.

Best Used For:

• Masonry & Brick Scoring: Making straight, chip-free relief cuts and joint score lines in hard-fired clay brick and concrete pavers with handheld grinders.
• Concrete Block Sizing: Slicing cinder blocks, pre-cast lintels, and structural masonry units up to 1-1/2 inches deep in a single dry pass.
• Stone & Tile Profiling: Trimming natural granite, fieldstone, and thick quarry pavers during landscape hardscaping and structural veneer installations.

Key Performance & Safety Features

• Continuous Turbo Rim Configuration: Fluted serrated rim channels cooling airflow and evacuates dense concrete dust rapidly to maintain low cutting friction.
• Industrial Diamond Matrix: Premium synthetic diamond crystals metallurgically bonded to the rim deliver extended service life over conventional bonded abrasives.
• 0.075-Inch Thin Plate Core: Hardened tensioned steel core reduces rotational resistance and minimizes aggregate blowout for cleaner cut edges.
• Multi-Arbor Mounting System: Features a standard 7/8-inch arbor with included precision brass adapter rings for 20mm (0.787 in) and 5/8-inch grinder spindles.
• High-Velocity 13,300 RPM Rating: Dynamically tensioned steel core handles maximum angle grinder speeds without blade wobble or distortion.

Technical Specifications

Pro-Tip: Allow the weight of the angle grinder and the 13,300 RPM rotational speed to drive the cut through cured concrete without excessive downward force; pushing too hard overheats the metal matrix and glazes over the diamond cutting crystals.
