POWERTEC 7 in. Segmented Rim Diamond Saw Blade For Concrete, Brick, Block and Asphalt The POWERTEC 7 in. Segmented Rim Diamond Saw Blade is engineered for tough cutting jobs through cured concrete, brick, pavers, block, and asphalt. Built with laser-welded segments, it offers lasting durability and consistent performance under demanding conditions. Its segmented rim and premium diamond grit deliver fast, precise cuts while minimizing heat buildup. Deep gullets between segments help remove debris and improve airflow, keeping the blade cool and extending its life. This blade supports both wet and dry cutting. Wet use reduces dust and improves edge quality, while dry cutting adds flexibility on job sites without water access. Designed for masonry, tile, and stone saws with a 7/8 in. arbor. Includes a 5/8 in. adapter ring for added compatibility with common tools.
