Industrial-Grade 4-1/2 Inch Premium Segmented Rim Diamond Saw Blade

The Bosch 4-1/2-Inch Premium Segmented Rim Diamond Saw Blade operates as a commercial masonry cutting disc engineered to execute rapid rough cuts through cured concrete, concrete block, red clay brick, and natural stone. Formulated with high-density industrial synthetic diamonds bonded to a tensioned steel core plate, this 7/8-inch round arbor blade functions on small angle grinders and compact circular saws at rotational speeds up to 13,200 RPM. Featuring deep expansion gullets that channel dust swarf out of the kerf, the unit maintains a 1-1/4-inch maximum cutting depth during high-speed wet or dry masonry modification without core plate warping.

Best Used For:

  • Concrete Block & CMU Modification: Slicing structural concrete masonry units (CMU), cinder blocks, and concrete wall footings during site prep.
  • Red Clay Brick & Mortar Cutting: Executing high-speed rough cuts through dense face bricks, refractory bricks, and mortar beds.
  • Natural Stone & Paver Trimming: Milling rough edges in fieldstone, granite pavers, slate tiles, and sand-lime bricks.

Key Performance & Safety Features

  • Industrial-Grade Synthetic Diamonds: Premium diamond formulation provides high-speed abrasive wear resistance and extended service life.
  • Segmented Rim Expansion Gullets: Deep rim slot geometry actively ejects masonry dust particles and vents thermal friction to prevent blade overheating.
  • Tensioned Steel Core Plate: Computer-balanced core plate minimizes lateral wheel chatter and maintains flat rotational tracking at 13,200 RPM.
  • Wet and Dry Application Range: Operates efficiently dry or wet to suppress crystalline silica dust during masonry cutting.
  • Universal 7/8-Inch Arbor Fit: Mounts directly onto standard 4-1/2-inch corded and cordless small angle grinders without spindle adapters.

Pro-Tip: When making full 1-1/4-inch deep dry cuts in hard concrete block or brick, avoid burying the blade completely in a single pass. Step-cutting in two shallow 5/8-inch increments allows airflow through the segmented gullets to cool the steel core plate, preventing thermal binding and matrix glazing.
