BES FLX3854 HSS Flex Bit 3/8 in. Diameter, 54 in. Long

When long reach and reliable, clean holes matter, the BES Products FLX3854 HSS Flex Bit delivers. Built for professional installers and contractors, this 3/8 in. diameter, 54 in. long flex drill bit offers the reach and durability needed for security, surveillance and monitoring system installations—drilling through walls, studs and conduit runs with minimal access. The Piranhabit FLX3854 pairs a premium M2 high-speed steel cutting head with a two-piece flexible shaft, giving you a sharp, aggressive 118° tip for fast penetration and spiral flutes that clear chips to reduce drag and heat. That combination means fewer bit changes, faster runs of cable and neater holes for mounts and anchors. Beveled shanks improve chuck grip, so you keep control when working on metal, wood or through embedded fasteners. Made in the USA and built for demanding jobsite use, this flex bit is an efficient choice for security integrators, low-voltage electricians and network cabling teams. Add the BES FLX3854 to your kit for cleaner, faster installations—ideal for CCTV, access control and structured cabling projects.
