Abstract: A rotating power tool assembly includes a rotating power base and a modular drive head. The rotating power base may be configured to rotate a spindle, and the modular drive head may be configured to be detachably coupled to the rotating power base. The modular drive head may comprise a torque control clutch, a working tip, and a torque value indicia. The torque control clutch may be non-adjustably structured to implement a torque limiting slip event that prevents the working tip from further rotation, despite continued rotation of the spindle, in response to the working tip being subjected to torque in excess of a discrete torque value. The torque value indicia may be externally visible and may comprise a visible characteristic that correlates to the discrete torque value.

The apparatus may further include calibration processing circuitry configured to receive the tool torque measurement measured by a tool torque sensor, and receive the calibrator torque measurement measured by a calibrator torque sensor.

Abstract: A measuring tape device may include a housing having an aperture, a reel assembly, a blade, and a piezoelectric bimorph layer. The reel assembly may be enclosed within the housing, and may be configured to alternately allow the blade to be withdrawn from the reel assembly through the aperture or received in the aperture onto the reel assembly. The blade may have a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly. The piezoelectric bimorph layer may be disposed over at least a portion of the blade.

Abstract: A guide assembly for a tape measuring device may include an inner guide portion facing a reel assembly of the tape measuring device, and an outer guide portion facing away from the reel assembly. The guide assembly may be configured to enable the tape to be paid out from an aperture of the tape measuring device in both lateral directions relative to the aperture.

Abstract: A torque wrench may include a head having a driving member configured to be operably coupled to a socket, a handle, a lever arm operably coupled to the head and the handle at respective opposing ends thereof, and a torque adjuster configured to enable a torque setting of the torque wrench to be adjusted. The torque adjuster may include a fixed member affixed to the lever arm and a movable member operably coupled to the fixed member. The handle may include a first end cap at a distal end thereof relative to the head and a second end cap at a proximal end thereof relative to the head, the second end cap being disposed proximate to the movable member.

Abstract: A saw blade holder may include a first guard member which may include a first groove configured to receive a first portion of an edge of a saw blade, a second guard member which may include a second groove configured to receive a second portion of the edge of the saw blade, a hinge that may be configured to couple the first guard member to the second guard member such that the first guard member may rotate relative to the second guard member to transition the saw blade holder between an open position and a closed position, and a locking member that may be affixed to one of the first guard member or the second guard member, the locking member may be configured to move into a locked position to secure the first guard member to the second guard member when the saw blade holder is in the closed position.
