Bosch DB442C Turbo Rim Diamond Blade 7/8 Inch

Product Description

The ROBERT BOSCH TOOL GROUP DB442C is a turbo rim diamond blade engineered for fast, smooth cutting through concrete and masonry materials. The blade measures 7/8 inches in diameter and accepts a 5/8 inch arbor, making it compatible with standard angle grinders used in the trades. High-quality diamonds are distributed deep into the bond matrix, which extends blade life and maintains cutting performance over repeated use. The turbo rim segment design increases cutting speed compared to standard continuous rim blades. This blade is typically installed and used by tile setters, masonry contractors, concrete finishers, and general contractors.

This diamond blade is suited for cutting concrete block, brick, pavers, stone, and similar masonry materials in both residential and light commercial applications. The 5/8 inch arbor fits common angle grinders used in field and shop settings. It ships in a package quantity of five blades per unit, making it practical for contractors stocking multiple tools or anticipating extended cutting jobs. Its smooth cutting profile reduces chipping on cut edges, which is useful when precision is required on exposed masonry surfaces.

Follow applicable OSHA and tool manufacturer safety guidelines for abrasive wheel use.
