Installer bits, also referred to as fishing bits, are special types of bits or drilling cable installation holes. The main feature that distinguishes an installer bit from others is that it is designed with a traverse hole that runs through the entire shank. After drilling a hole, a wire is passed through the hole and the drill removed. Then, the wire is used for pulling a cable through the drilled hole. The drills are made of hardened materials such as alloy steel and are recommended for drilling holes in cement bricks, and blocks. Because the aim of drilling holes using installer bits is to install cables, some of them are as long as 18 inches. The installer bits are created to be operated using hand-portable power tools
. The bits come in handy when you want to install cables for computer networking, surveillance cameras, security wires, and television cables. Visit our site to see the different installer bits.
