Abstract: An accessory tool for an oscillating power tool includes a mounting portion, and a blade portion that extends from the mounting portion. The blade portion includes a first lateral edge portion, a second lateral edge portion, and a leading edge portion. A cutting edge is defined in the second lateral edge portion that includes a rearward facing portion that extends generally laterally from a distal end portion of the second lateral edge portion toward the first lateral edge portion and a forward facing cutting edge portion that extends from said second lateral edge portion toward said first lateral edge portion. The rearward facing cutting edge portion is at least partially interposed between the leading edge portion and the mounting portion, and the forward facing cutting edge portion is at least partially interposed between the rearward facing cutting edge portion and the mounting portion.

Abstract: An adapter is provided for coupling an accessory tool to any of a plurality of power tools wherein each of the plurality of power tools has a distinct tool drive structure. The adapter has body that includes a first side surface, and a second side surface positioned opposite to the first side surface. An inner peripheral surface extends from the first side surface to the second side surface that defines a central opening, and an outer peripheral surface extends from the first side surface to the second side surface. The first side surface has defined therein a plurality of recesses positioned around the central opening. In addition, the body has a first adapter drive structure and a second adapter drive structure. The first adapter drive structure and the second adapter drive structure define the plurality of recesses, and the first adapter drive structure and the second adapter drive structure each possesses a distinct configuration in comparison to each other.

Abstract: A handpiece for a rotary tool including a flexible power shaft configured for connection at one end to the rotary tool, and at the other end to the handpiece, with at least one locking formation affixed to the shaft. The handpiece includes a housing having a first end for receiving the shaft, and a second end configured for accommodating a working attachment, the housing defining a central throughbore for rotatably receiving the shaft. At least one locking actuator is disposed in the housing for releasable engagement with the locking formation, the handpiece being provided with a biasing force for biasing the actuator out of engagement with the locking formation, so that a user-applied force on the actuator overcomes the biasing force to enable locking engagement between the actuator and the locking formation. A working end of the handpiece housing has an endcap and is also configured for receiving supplemental attachments.

Abstract: A cutting and grinding wheel made of a circular disk having a center, two opposing surfaces, an outer circumference, and a center defining a bore hole. A plurality of teeth are evenly distributed around the disk's outer circumference, with each tooth having an apex and a pair of opposing sidewalls generally parallel to the disk opposing surfaces. The teeth formed in a generally sinusoidal pattern, and each adjacent pair of teeth are separated by a gullet. An abrasive coating is disposed to be concentrated upon the wheel teeth apexes and opposing teeth sidewalls.
