An extension assembly configured to permit a user to drill a hole through inaccessible areas in a wall is disclosed. The extension assembly includes a flexible, solid core rod having first and second ends and a holding means. The rod is configured to extend through a hole in a wall cavity and flex therein to position a tool bit at an inaccessible location in the wall cavity and permit a user to drill a hole through a substrate at the inaccessible location. The holding means is secured to the second end of the rod for releasably holding a tool bit for rotation with the rod and includes a sleeve adapted to slide axially along a body of the holding means between a secured position where a tool bit is securely held within the holding means and a release position where the tool bit is released from the holding means.

Flexible and extendible drill bit assembly

A flexible, extendable extension assembly used to create extended length holes and holes through inaccessible areas in walls and framing. The extension assembly including a flexible, solid core rod having first and second ends; and a holding means secured to the first end of the rod for releasably holding a tool bit for rotation with the rod.

A lockset drilling guide that comprises a frame is provided. The frame comprises a first flange and a second flange. The second flange is capable of flexing relative to the first flange. The lockset drilling guide further comprises at least a first opening and a second opening defined in the frame. The first opening is positioned at approximately 90 degrees relative to the second opening. A positioning member is mounted on the frame, wherein the positioning member is laterally movable to at least two positions relative to the frame. The frame is configured for mounting on a door to facilitate the forming of holes in the door for the installation of a lockset.

Lockset drilling guide

A lockset drilling guide and a method of forming holes in a door are provided. The drilling guide includes a frame and at least a first opening and a second opening defined in the frame. The first opening is positioned at approximately 90 degrees to the second opening. The frame is configured for positioning on a door to facilitate the forming of openings in a door for the installation of a lockset. The method includes the steps of providing a frame having at least a first opening and a second opening defined in the frame; positioning the frame on an edge of the door; inserting a first holesaw at least particularly into the first opening and drilling a first hole in the door; inserting a second holesaw at least partially into the second opening and drilling a second hole in the door; and removing the frame from the door.
