Abstract: The self feeding drill bit comprises a shank that has one end adapted to be connected to a chuck of a rotary tool such as a drill or power driver. The opposite end of the shank supports a cutting member where the cutting member is a cup shaped member having a series of teeth formed on the edge thereof. A screw tip is provided for feeding the cutting member into and through the wood. A removable cutting blade is provided for boring the interior of the hole. A kit including a self feed bit and a plurality of replacement bits is also provided.

Abstract: The self feeding drill bit comprises a shank that has one end adapted to be connected to a chuck of a rotary tool. The opposite end of the shank supports a cutting head having a series of teeth formed on the edge thereof for cutting the periphery of the hole. A screw tip may be provided for feeding the bit into and through the wood. A plurality of cutting blades is provided for boring the interior of the hole. The cutting blades define a plurality of cutting edges that are disposed at different angles to a plane perpendicular to the axis of rotation.

Abstract: A drill bit comprises a shank having a longitudinal axis. A cutting head is formed at one end of the shank. A removable and replaceable pilot tip such as a screw tip or pilot point is formed on the cutting head. The pilot tip is designed for controlled failure. A tool is also provided for removing the broken tip. A kit comprising a dill bit adapted to receive a removable tip, a removable tip for attachment to the cutting head, and/or a removal tool for removing a broken tip from the drill bit. A method for removing a tip from a drill bit and replacing it with another tip is also provided.

Abstract: The drill bit comprises a cutting blade formed at one end of a shank. The cutting blade has a pair of cutting shoulders that extend inwardly from the outer sides of the blade toward the bit axis. A tip having converging sides that create a point extends from the shoulders. The cutting edge of each shoulder is beveled with respect to the plane of the face of the blade. A flute is provided on the leading portion of each blade face adjacent the cutting edges. Each flute is a smooth curve that creates a substantially uninterrupted recess on each face of the blade that facilitates chip removal, increases the drill rate and lowers the power required to drill a hole. A non-stick coating may be applied to the blade to further facilitate chip removal.

Abstract: A drill bit comprises a shank defining a longitudinal axis. A cutting head is formed at one end of the shank. At least one cutting edge and a centering point are formed on the cutting head. The shank and a portion of the cutting head are formed of a first material. The cutting edge, centering point and a portion of the cutting head are formed of a second material. A weld joins the first material and the second material. A first blank is welded to a second blank. A cutting head is milled into the first blank and second blank such that the cutting head is formed of the first material and the second material.

Abstract: The bit has a longitudinally extending shank having a quick release connection formed at one end thereof for attachment to a driving tool such as a drill. The opposite end of the shank is formed with a cutting member. The cutting member is formed as a twisted planar member having a generally helical shape. A screw tip is provided along the longitudinal axis of the bit for guiding the bit through the workpiece.

Abstract: 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.

Abstract: A cutting tool consists of a cutting body extending from a front end to a rear end and defined by at least an exterior surface. A shank is connected to the cutting body at the rear end. The cutting body is provided with a slightly concave base surface positioned at the front end. A pilot unit extends outwardly from the base surface and is defined by at least an outside surface thereof. First and second surfaces extend inwardly from the exterior surface of the cutting body and intersect each other to form a flute. The first surface, second surface and the flute extend into the pilot unit. A cutting edge of the cutting tool is formed at the intersection of the first surface with the base surface of the cutting body.

Abstract: A drill for piloting holes, drilling holes, countersinking and counterboring holes in wood or wood-like materials comprises:(a) a plurality of coaxial, stepped sections with cutting interfaces between,(b) at least one radial flute,(c) chucking means, and(d) a counterboring section.
