Abstract
A 360° rotatable drill shear attachment has a housing with forward extending shear blades and a rearward extending drive bit connectable to a chuck of a portable hand drill. A cowling is fixed to a mounting flange and rearward of the shear housing protectively covering the drive bit and drill chuck. A circular clamp is rotatable and securable to the mounting flange. Left and right rails slide-ably adjust lengthwise and pivotally extend from the clamp along the left and right sides of the drill body to a point beyond the rear of the drill body to a drill rear end. A connector adjustably is fastened to the rear ends of the rails to adjustably draw the ends together for securing the shear attachment to the drill body. The clamp may be loosened to rotate the mounting flange of shear attachment, and shear blades, within the clamp for shear blade orientation anywhere along a 360° axial arc. After which, the clamp is tightened for safe, one-handed operation of the drill with the shear attachment and shear blades oriented in the desired direction.
