BES FLX3848H Piranhabit, 3/8" 48", High Speed Steel Flexible Shaft Drill Bit with Wire Pull Hole

Designed for installers who need reliable, repeatable results, the BES Products FLX3848H Piranhabit flexible shaft drill bit makes quick work of low-voltage and security jobs. This high-speed steel (M2) flex drill bit combines a 3/8" cutting diameter and an extended 48" overall length to reach behind panels, inside conduit runs, and through framing without disassembly. The aggressive 118° tip and fast spiral flutes drill clean holes through wood, metal, and mixed materials while reducing bind-up and heat. A built-in wire pull hole lets you feed security, surveillance and monitoring cables as you drill—saving time on camera and access control installs. The beveled shank improves chuck grip to prevent slippage during high-torque work, and the two-piece construction pairs a hard cutting bit with a more flexible shaft for durability where it matters. Powder-coated finish resists corrosion on job sites. Whether you're mounting cameras, running Cat/Coax, or doing general low-voltage work, the BES FLX3848H is engineered to improve speed, control, and cable management. Add it to your toolkit to streamline installations and reduce callbacks.

• Speeds up installations by drilling fast, clean holes for security and surveillance cable runs
• Flexible shaft reaches tight or long drill paths so you can pull wire through walls and conduits
• Premium M2 HSS construction stays sharp longer for fewer bit changes and consistent performance
• Beveled shank and aggressive 118° tip reduce slip and deliver reliable grip in any drill chuck
• Two-piece design with a built-for-flex shaft and a hard cutting bit minimizes breakage and maximizes control
