This invention comprises a leverage attachment for a power drill having a grip. The leverage attachment has a bracket for mounting to the housing of the power drill. A lever arm is pivotally mounted at one end to the bracket. The lever arm has an eyelet adjustment to the pivotal mounting of the arm. A link chain is mounted at one end to the eyelet of the device and is adapted to extend around the material to be drilled. The device has a hook connected to the one end of the chain and adapted to be hooked to one of the links of the other end of the chain to position the chain taunt about the material when the drill is in position upon the material for drilling, so that the operator may with one hand push upon the grip of the power drill and energize the drill and with the other hand push the lever arm upward to push the drill downward relative to the chain and thereby to push the drill bit of the drill downward upon the material to provide additional downward leverage force upon the drill bit in engaging the material.
