Abstract: A step drill bit includes a shank and a body that defines a plurality of axially stacked, progressively sized steps including a first step, a terminal step, and a plurality of intermediate steps having incrementally increasing diameters disposed between the first and terminal steps. The step drill bit includes a flute in the body extending from the distal end to the proximal end and a plurality of cutting edges formed in the body. Each cutting edge is disposed along one of the plurality of steps. Each cutting edge defines a helix angle and a radial rake angle. The helix angle of the cutting edge at a first intermediate step of the plurality of intermediate steps is greater than the helix angle at the first step. The radial rake angle of the cutting edge at the first intermediate step is greater than the radial rake angle at the first step.

Abstract: A tool bit includes a drive portion configured to be selectively coupled to a tool. The drive portion is composed of a first material. The tool bit includes a working end portion having a shape configured to correspond with a recess of a fastener for the working end portion to engage and drive the fastener. The working end portion includes a first segment and a second segment. The first segment is located between the second segment and the drive portion. The first segment is composed of the first material. The second segment is fixed to the first segment at a connection interface. The second segment is composed of a second material different than the first material.

Abstract: A drill bit includes a body having a first end, a second end opposite the first end, and an axis of rotation extending centrally through the body. The drill bit includes a cutting head with a cutting tip on the axis of rotation and a cutting portion. The cutting portion includes first tip surfaces on opposite sides of the axis of rotation and second tip surfaces on opposite sides of the axis of rotation. Each first tip surface extends radially outward from the cutting tip to a corresponding second tip surface. Each second tip surface extends from a corresponding first tip surface to an outer periphery of the body. The first tip surfaces define a first tip angle measured through the axis of rotation that is oblique. The second tip surfaces define a second tip angle measured through the axis of rotation that is smaller than the first tip angle.

Abstract: A drill bit includes a shank extending along a bit axis and a body with a proximal end adjacent the shank and a distal end opposite the proximal end. The body defines a plurality of axially stacked, progressively sized steps including a first step at the distal end and a terminal step at the proximal end. The drill bit also includes a flute in the body. The flute defines an elongated groove that extends from the distal end to the proximal end. The drill bit further includes a plurality of cutting edges formed in the body. Each cutting edge is disposed along one of the plurality of steps and defines a helix angle and a rake angle. The helix angle of the cutting edge at the terminal step is greater than the helix angle of the cutting edge at the first step. A ratio of the helix angle to the rake angle of the cutting edge at the first step is in a range from 0.5 to 2.4, and a ratio of the helix angle to the rake angle of the cutting edge at the terminal step is in a range of 0.9 to 1.7.

Abstract: A tool bit may include a first end, a second end, and a longitudinal axis, an insertion end portion adjacent the first end, a working end portion adjacent the second end and configured to be inserted into a fastener a first distance measured from the second end. The working end portion including a first segment and a second segment that is fixed to the first segment at a connection interface, and a first maximum outer dimension measured perpendicular to the longitudinal axis. The connection interface is located a second distance measured from the second end. The tool bit further includes a shank disposed between the insertion end portion and the working end. The shank includes a second maximum outer dimension measured perpendicular to the longitudinal axis, wherein the second maximum outer dimension is less than the first maximum outer dimension.

Abstract: A die head for cutting threads in a pipe. The die head includes a drive portion, a die retention portion, a cap, and a plurality of windows. The drive portion has a plurality of recesses configured to receive torque from a pipe threading machine. The die retention portion includes a plurality of die posts. Each die post is configured to receive a die having teeth for cutting the threads in the pipe. The cap is coupled to the die retention portion. Each window is defined between each pair of adjacent die posts and the cap. An end of each die adjacent the cap is visible through a corresponding window of the plurality of windows such that all of the teeth of the die are visible through the corresponding window.
