Milwaukee 3/8" x 18" Bell Hanger Bit 48-13-7137
PRECISION WIRE ROUTING AND HIGH-SPEED DRILLING FOR LOW-VOLTAGE SYSTEMS
When you're pulling security, phone, or data lines through wall cavities and deep headers, efficiency is the difference between a profitable job and a long day. This 18-inch bell hanger bit is designed specifically for the low-voltage professional, offering the reach needed to clear structural members without losing your path. The aggressive tip geometry bites into wood instantly, while the non-stick coated flutes ensure that debris is cleared quickly to prevent binding in tight spaces. The most critical feature is the integrated pull-through hole in the tip; once you've punched through the header, simply attach your wire and pull it back through the wall in one fluid motion, eliminating the need for separate fish tapes in many standard residential and commercial installs.
- / Aggressive tip geometry delivers rapid penetration through wood and light-gauge materials to keep your install moving.
- / Integrated pull-through hole in the bit tip simplifies wire routing by allowing you to pull cable back through the hole immediately after drilling.
- / Non-stick coated flutes significantly reduce friction and binding, ensuring faster chip ejection in deep-hole applications.
- / 3-Flat Secure-Grip™ shank prevents the bit from spinning in the chuck under high torque, providing maximum power transfer.
