Tools and methods for creating a plurality of aligned holes from a plurality of near full-sized holes. The tool includes a cutting member having a first diameter and a pilot member connected to and coaxial with the cutting member. A first section of the pilot member includes a centering member and is positioned between the cutting member and the second section having a second diameter. The centering member may include a cutting surface. The second diameter corresponds to a positional tolerance of misalignment of a plurality of near full-sized holes of the same diameter and a full-size hole diameter. The centering member may have a third diameter between the first and second diameters. The centering member may be tapered. The pilot member may be inserted into a plurality of near-full sized holes and the cutting member may cut through the holes to form a plurality of aligned full sized holes.

A boring tool may include a coupling portion for interfacing with a powered driver, a shank operably coupled to the coupling portion, a cutting portion operably coupled to the shank, and a cutting portion. The cutting portion may be defined by a plurality of helical cutting flutes. The cutting tip may be operably coupled to a distal end of the cutting portion relative to the shank. The coupling portion, the shank, the cutting portion and the cutting tip may all share an axis. The cutting tip may include an inner portion and an outer portion. The inner portion may be defined by inner faces bisected by the axis and extending a first radial distance away from the axis to define a first point angle between the inner faces. The outer portion may be defined by outer faces extending from respective ones of the inner faces at the first radial distance to a second radial distance equal to a radius of the cutting portion to define a second point angle between the outer faces, and the second point angle may be less than the first point angle.

A drill bit includes a body having a first end, a second end, and an axis of rotation extending centrally through the body from the first end to the second end. The drill bit also includes a shank adjacent the second end. The drill bit further includes a cutting head adjacent the first end. The cutting head includes a pilot tip and a cutting portion. The cutting portion has first tip surfaces and second tip surfaces on opposite sides of the pilot tip. Each first tip surface extends radially outward from the pilot tip to a corresponding second tip surface. The first tip surfaces define a first tip angle through the axis of rotation that is less than 180 degrees. The second tip surfaces define a second tip angle through the axis of rotation that is smaller than the first tip angle.

An auger includes a body having a first end, a second end, a stem that defines an axis of rotation, and a flute helically wrapped around the stem. The auger also includes a shank at the first end of the body and a cutting head at the second end of the body. The cutting head includes a cutting edge, a cutting face adjacent the cutting edge, and a back taper surface extending from the cutting edge in a direction opposite the cutting face. The back taper surface defines a back taper angle between an axis perpendicular to the axis of rotation and the back taper surface. The back taper angle is a non-zero angle. The cutting head further includes a feed screw extending from the stem along. The feed screw includes a thread having a pitch and a depth. The pitch is larger than the depth of the thread.

An auger includes a body having a first end, a second end opposite the first end, a stem that extends from the first end to the second end and defines an axis of rotation, and a flute helically wrapped around the stem. The auger also includes a shank at the first end of the body configured to be received by a power tool and a cutting head at the second end of the body. The cutting head includes a cutting edge, a spur, a feed screw with a thread, and a cutting face positioned adjacent the cutting edge. The cutting head defines a step at an interface with the body, and wherein the cutting head has a maximum diameter that is greater than a maximum diameter of the body.

Orthopedic systems and methods for installing an implant and/or boring a bone bicortically. The system may include a drill having a proximal boring portion configured to bore a larger hole in a bone more efficiently when the drill rotates in a first direction compared to an opposite second direction, and a distal boring portion configured to bore a smaller hole in the bone more efficiently when the drill rotates in the second direction. The implant may be configured to be implanted at least partially in the bone, such that a first region of the implant is located in the larger hole and a second region of the implant is located in the smaller hole. In an exemplary method, the larger hole and the smaller hole may be bored in the bone's near cortex and far cortex, respectively, by a shaft and a nose of the drill rotated in opposite directions.

A method for enlarging each one of an initial pair of holes, which includes a first hole, extending through a first component, and a second hole, extending through a second component, includes inserting a pilot member, corresponding to a tolerance of misalignment of the first hole and the second hole of the initial pair of holes, such that pilot member passes through a clearance gap, defined by at least a portion of a boundary of first hole and at least a portion of a boundary of second hole with pilot member having a first central axis. The method also includes cutting a second pair of aligned holes through first and second components, respectively, with a cutter section, which has a second central axis.

An auger includes a body with a first end, a second end opposite the first end, a stem that extends from the first end to the second end and defines an axis of rotation, and a flute helically wrapped around the stem. The auger further includes a shank at the first end of the body configured to be received by a power tool and a cutting head at the second end of the body. The cutting head includes a cutting edge, a spur, and a feed screw with a thread. The thread has a pitch and a nonsymmetrical thread profile. The pitch of the thread is at least 2.5 mm.

A method employing an apparatus in conjunction with a hammer-drill to penetrate composite metal and non-metal structure or structures including, for example, thick metal or rebar encountered during concrete, rock or masonry boring operations without requiring a change in drill equipment.
