Tackle long, hard-to-reach masonry drilling with confidence using the BES Products FLM3848 Carbide Masonry Flex Bit. Designed for installers who run conduit and cables for security, surveillance and monitoring systems, this 3/8 in. diameter, 48 in. long flex bit combines a tungsten carbide cutting tip with a flexible spring-steel shaft to deliver fast, precise holes in concrete, stone and masonry.
