Also known as wire installers, bell hanger drill bits have a hole near the drill point of the tool for threading wire onto the bit to pull it back through the workpiece after drilling. These bits are frequently used when installing telephone, cable, internet, and security systems.
Bend around obstructions when drilling in hard-to-reach areas. Flexible shank bits are commonly used in construction and electrical applications for running cables and wires through floors, studs, and walls.

Round shanks, also known as straight shanks, are the most common shank style for drill bits. They fit into a standard 3-jaw chuck or a collet chuck on a drill and provide more accurate centering than 3-flat or hex-shank bits, but the chuck must be tightened to keep the bit from slipping.
High-speed steel is the most common choice for general-purpose drilling because it's typically compatible with steel, wood, plastic, and nonferrous metals. Carbide tipped tools offer the strength and wear resistance of carbide steel on just the cutting edge when you don't need the full strength and rigidity of solid carbide bits. These bits are often used for dry drilling.

Switch-Bit Flexible Shanks
Choose from shanks in a range of lengths to provide the reach and flexibility you need when installing wires and cables. Interchangeable switch-bit drill heads attach to the shank to adapt the tool for different applications.
These shanks can be used in a standard drill chuck and have a 3-flat shank to help keep the tool from slipping in the drill chuck.

Switch Bits for Flexible Shanks
Attach one of these interchangeable switch-bit drill heads to a compatible switch-bit flexible shank to optimize the tool for drilling into different materials when installing wires and cables.
