    Abstract: A step drill bit including a shank extending along a bit axis and a body having a proximal end adjacent the shank and a distal end opposite the proximal end. The body includes a bit tip adjacent the distal end. The bit tip includes a diameter in a direction perpendicular to the bit axis. The body defines a plurality of axially stacked, progressively sized steps including a first step adjacent and a terminal step. Each step of the plurality of steps defines a length and a diameter. The step drill bit also includes at least one flute in the body. Each flute extends from the distal end to the proximal end. The step drill bit includes a cutting edge on the flute. A ratio of the diameter of the bit tip to the length for a majority of the plurality of steps is in a range from 1.0 to 1.5.

    Abstract: A lockable adapter is configured to couple a drive socket to a tool. The lockable adapter includes a body defining a longitudinal axis. The body is configured to couple the lockable adapter to the tool. The lockable adapter includes a sleeve moveably coupled relative to the body along the longitudinal axis of the body between a first position and a second position. The sleeve is configured to interface with the drive socket to support the drive socket on the sleeve. The lockable adapter includes a collar moveable relative to the sleeve. The sleeve moves into the second position configured to lock the drive socket to the sleeve in response to inserting the drive socket onto the sleeve. The sleeve moves into the first position configured to allow removal of the drive socket from the sleeve in response to moving the collar relative to the sleeve.

    Abstract: A tool bit includes a drive portion configured to be engaged by a tool, the drive portion including a first maximum outer dimension, a shank extending from the drive portion and including a reduced outer diameter, and a tip coupled to an end of the shank opposite from the drive portion. The tip includes a compressive residual stress layer formed by blasting to increase a wear resistance of the tip relative to the shank. The tip additionally includes a second maximum outer dimension. The reduced outer diameter of the shank is smaller than the first maximum outer dimension of the drive portion and the second maximum outer dimension of the tip.

    Abstract: A lockable adapter is configured to selectively couple a drive socket to a power tool. The lockable adapter includes a shaft configured to couple the lockable adapter to the power tool for the power tool to rotate the lockable adapter about an axis, a drive member movable along the axis relative to the shaft, and a retaining member supported by the drive member. The drive member is configured to interface with the drive socket to support the drive socket on the lockable adapter. When the lockable adapter is in a locked state, a portion of the retaining member protrudes beyond a surface of the drive member such that the retaining member is configured to secure the drive socket to the drive member. When the lockable adapter is in an unlocked state, the retaining member is configured to allow for removal of the drive socket from the drive member.
