1/4" x 24" Bellhanger Drill Bit

The Milwaukee 48-13-7325 Bellhanger Drill Bit is a 1/4" diameter, 24" long drilling solution designed for installing computer, security, phone, and cable wire systems. This bit provides extended reach in tight spaces and features a pull-through hole at the tip to simplify wire routing through drilled openings. Built for electricians, low-voltage installers, and telecom technicians, it combines aggressive cutting geometry with a secure-grip shank that prevents spinning in the drill chuck.

• Aggressive Tip Geometry: The bit's tip is engineered for faster penetration through wood framing, wall studs, and joists. This design reduces drilling time on every hole, so you finish wire runs faster.
• Non-Stick Coated Flutes: The flutes feature a coating that minimizes friction and prevents wood chips from binding inside the channels. Fast chip removal means less heat buildup and longer bit life.
• Pull-Through Hole in Tip: A machined eyelet at the tip allows you to thread wire directly through the hole after drilling. This eliminates the need for separate fish tape on many pulls, cutting installation steps.
• 3-Flat Secure-Grip Shank: Three flat surfaces machined into the shank create positive contact with drill chuck jaws. The bit locks firmly in place and won't slip under torque, even in high-speed applications.
• 24" Extended Length: The 24" reach lets you drill through multiple stud cavities or cross deep wall assemblies in a single pass. Fewer repositioning steps mean faster rough-in work.
• Versatile Wire System Application: Designed for all small-gauge wire installations including ethernet, coaxial, alarm, speaker, and telephone cable. One bit handles the full range of low-voltage trade work.

This bellhanger bit fits any corded or cordless drill with a 3-jaw chuck capable of gripping a 1/4" shank. Milwaukee offers this bit in 12", 18", and 24" lengths to match different wall depths and reach requirements. The coated flutes and aggressive tip work in softwood and hardwood framing lumber commonly found in residential and light commercial construction.

Insert the 3-Flat shank fully into the drill chuck and tighten securely so all three flats contact the jaws. Apply steady forward pressure during drilling to let the aggressive tip geometry do the cutting work without forcing the bit. After each use, wipe the flutes clean of wood debris and inspect the tip eyelet for damage or clogging. Store the bit in a protective case to prevent bending the long shaft.

A: A bellhanger drill bit is a long, thin bit designed specifically for drilling holes through wall studs and floor joists to run wire. The name comes from its original use by telephone installers (bellhangers) who needed to route wire over long distances through building cavities. Modern bellhanger bits like the Milwaukee 48-13-7325 include a pull-through hole at the tip, allowing installers to thread wire directly through the bit after drilling, which speeds up low-voltage cable installation.
