An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

A surgical sagittal saw with a complementary blade. The blade is formed with a void to receive a pin associated with the saw that releasably holds the blade to the saw. The blade and the pin have complementary tapered surfaces. When the tapered surface of the pin moves against the tapered surface of the blade, the blade is urged against a static surface of the saw.

An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

An accessory for coupling to an oscillating power tool includes a working end portion and an attachment portion. The working end portion defines and extends along a working axis. The attachment portion is coupled to the working end portion and includes a top wall, a bottom wall spaced apart from the top wall, and a peripheral wall extending from the top wall to the bottom wall at least partially around the top wall to form at least a portion of a polygonal shape. A generally U-shaped opening is defined in the top wall, extends along an attachment axis at an angle to the working axis, has a central portion at a center of the attachment portion, and is open to a gap in the peripheral wall. A plurality of radial openings is defined in the top wall and arranged between the U-shaped opening and the peripheral wall. The peripheral wall, the U-shaped opening, and the plurality of radial openings are configured to couple the attachment portion to at least two different configurations of accessory attachment mechanisms on different oscillating power tools.

An accessory for an oscillating power tool includes an attachment portion configured to be coupled to an oscillating power tool and a working portion coupled to the attachment portion and extending generally along a longitudinal axis. The working portion has a generally planar wedge shape bounded at least partially by a rear non-cutting end with a first width, a front cutting edge opposite the rear edge with a second width that is greater than the first width, a first side cutting edge extending from a first end of the rear end to a first end of the front cutting edge at a first angle to the longitudinal axis, and a second side cutting edge opposite the first side cutting edge and extending from a second end of the rear end to a second end of the front cutting edge at a second angle to the longitudinal axis.

An accessory for a power tool includes a body having a mounting portion configured to engage with a mounting device of the power tool. The body also includes a working portion that is applied against a workpiece to effect a desired change to the workpiece such as cutting. The accessory also includes a working plate that is fixed to the working portion and cooperates with the working portion to improve the cutting quality of the accessory including providing a precise cut start. The working plate has a hardness that is greater than that of the body.

A device for taking a sample from a solid body by cutting out, having a frame and a cutting tool retained on the frame in such a way that the cutting tool can be moved relative to the frame, wherein the cutting tool, at least in parts, at least substantially has the shape of a hollow spherical cap or a hollow spherical segment. A method for taking a sample from a solid body by cutting out is implemented with the device.

An accessory tool for an oscillating power tool includes a blade portion including a first lateral edge portion, a second lateral edge portion, and a leading edge portion, the leading edge portion defining a cutting edge. A reinforcement structure extends linearly across the blade portion from a first position located on the leading edge portion proximate the first lateral edge portion to a second position located on the second lateral edge portion and spaced apart from the leading edge portion. The reinforcement structure defines a cutting zone that encompasses a leading region of the blade portion between the reinforcement structure and the leading edge portion, the reinforcement structure being configured to increase a stiffness of the blade portion.

A working attachment for a power tool is provided. The working attachment is able to be driven by the power tool to oscillate around a central axis. The working attachment includes a working portion for realizing a function of the working attachment and a connecting portion for connecting the working attachment with the power tool. The connecting portion includes at least two driven points for receiving a driving force of the power tool. The at least two driven points are disposed in a plane which is substantially perpendicular to the central axis and located between an upper end and a lower end of the connecting portion in a direction of the central axis.
