Abstract: Devices and methods for automatically controlling a step bit operation in a power tool. The method includes generating, by a sensor of the power tool, sensor data indicative of an operational parameter of the power tool wherein a step bit is coupled to the power tool. An electronic control assembly of the power tool receives the sensor data, where the electronic control assembly includes an electronic processor and a memory. The memory stores a machine learning control program for execution by the electronic processor. The electronic control assembly processes the sensor data using a machine learning control program of the electronic control assembly and generates, using the machine learning program, an output based on the sensor data. The output indicates step bit progress information. The electronic control assembly controls a motor supported by the housing of the power tool based on the output.

Abstract: A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.

Abstract: A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

Abstract: A vibration damping toolholder for a metal cutting tool, the toolholder including a holder body provided with an internal cavity, which extends inside the holder body along the longitudinal axis, and which has a first cavity end at a first holder body end. The damping toolholder further includes a tuning mass, which is movably arranged inside the cavity and extends along the longitudinal axis, and which has a first tuning mass end at the first holder body end. The damping toolholder also includes a damping medium, which surrounds the tuning mass inside the cavity, and a single primary spring element, which is positioned inside the cavity. An outer spring element end is immovably fixed to a first cavity end at the longitudinal axis, and an inner spring element end is immovably fixed to the first tuning mass end at the longitudinal axis.

Abstract: A boring tool includes a coupling portion, a shank, and a cutting portion. The shank further includes a torsion release neck, having a smaller diameter cross section than a first end of the shank and a second end of the shank, a first transition to the first end of the shank, and a second transition to the second end of the shank. A torsion release neck has a lower polar moment of inertia than other portions of the boring tool so that it may guide torsional loading and shear stresses in the boring tool away from the cutting and coupling portions to improve the durability of the boring tool as a whole.

Abstract: An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.
