BellHanger Drill Bits
Common tools of the trade for electricians and cable installers, bell hanger drill bits (or installer bits) are twist drills that feature a transverse hole drilled through the bit near the tip that enables the pulling of wire through walls, ceilings and floors. After penetrating the wall, a wire can be threaded through the hole and pulled through the hole as the bit is withdrawn. The wire in turn pulls a cable back through the wall. Manufactured Irwin Tools, bell hanger bits, also known as installer bits or fishing bits, perform well in wood, metal lathe, plaster and wallboard drilling applications. The fluted design facilitates speedy chip removal.
