A tool system includes at least one machining tool, in particular at least one oscillating machining tool, and at least one additional machining tool, in particular at least one additional oscillating machining tool. The at least one machining tool and the at least one additional machining tool are of the same type, and the at least one machining tool and the at least one additional machining tool differ from each other in at least one cutting blade characteristic, in particular cutting edge characteristic.

A cutting tool mechanism and cutting tool (11) including the mechanism (31), for cutting hard material such as concrete and stone is disclosed. The tool (11) has one or two blades (23), (25) each driven by a mechanism (31). Each mechanism (31) has an input coupling 35 for transmission of rotary motion from a motor, and an output coupling (141), (143) to transmit resultant orbital, oscillatory or impact motion to the blade (23), (25). A suspension or sliding coupling located between the output coupling (141), (143) and the blade (23), (25), is provided, through which motion to the blades is transmitted. The suspension or sliding coupling absorbs impacts of the blades with the material being cut, rendering the tool more controllable.

An axially mounted non-circular hole saw device follows a lateral, oscillating cutting motion to cut a non-circular kerf in a workpiece. The device adapts to variously styled power tools. The device couples to a power tool at an axial orientation through a mounting portion. The axial disposition of the device relative to the power tool enables the axial vibratory force generated by the power tool to convert to a lateral, oscillating cutting motion followed by the device. This cutting motion forms a clean non-circular kerf, offsets vibrations during cutting, and minimizes debris formed during cutting. A cutting portion has a non-circular shape. The cutting portion includes a base edge and a teeth edge. A bridge traverses the base edge for stability. A mounting portion extends perpendicularly from the bridge portion. The mounting portion includes a gap defined by slots that couple to a coupling mechanism from the power tool.

The present disclosure relates to a saw, comprising a drive, a first blade configured to oscillate about an axis perpendicular to a plane defined by a surface of the first blade, a second blade configured to oscillate about an axis perpendicular to the plane in a direction opposite to that of the first blade, and wherein gearing is provided between the drive and the first and second blades to reduce the speed transmitted from the drive to the blades. A saw blade, a connection mechanism for connecting a blade to a saw and associated methods are also provided.

A hole saw includes a base member configured to secure the hole saw to a drive device and a plurality of blade members where each blade member is connected to and disposed orthogonally to the base member via a respective extender. Each blade member has cutting teeth extending in a respective cutting direction and distances between the cutting teeth and the base member vary along the respective cutting direction of the respective blade members. Each respective extender is configured cantilever support opposite, freestanding distal ends of the respective blade member where each distal end of each respective blade member is disconnected from the distal end of an adjacent blade member.

A power tool attachment saw according to the invention is provide and includes a body plate, a connector section and a plurality of cutting walls. The body plate is a planar body and the connector section positioned on one side of the planar body and adapted for attachment to an oscillating power tool. The plurality of cutting walls are positioned orthogonal to and extend from exterior edges of the planar body to form a material receiving space. The plurality of cutting walls provide a uniform cutting edge about the material receiving space.

A hole saw includes a base member configured to secure the hole saw to a drive device and a plurality of blade members extending orthogonally to the base member. The blade members are configured to cut into a structure to form a polygonal opening in the structure in response to rotational movement of the hole saw by the drive device. Each blade member is attached to the base member in a fixed position relative to the base member and has cutting teeth extending in a respective cutting direction. First and second blade members of the plurality are disposed parallel to each other and have I-shaped faces that face each other. Third and fourth blade members of the plurality are disposed parallel to each other and have I-shaped faces that face each other.

A saw blade includes a blade body having a top surface and a bottom surface, wherein the blade body is at least partially comprised of a first composite material or a metal; a cutting edge on a distal end of the blade body; and a coupling configured to connect the blade body to a handpiece adapted to oscillate the blade body. The saw blade may include: a first inlay portion and a second inlay portion, where the first inlay portion is either embedded in the top surface or covers the top surface, and the second inlay portion is either embedded in the top surface or covers the bottom surface; or an inlay portion sandwiched between a top portion and a bottom portion of the blade body.

A surgical saw blade including a cutting edge, blade body and a coupling for connecting the blade body to a handpiece. The blade body at least partially includes a composite material that helps to confer optimal weight and rigidity to the saw blade to allow for minimal vibration during use and minimal mechanical load on the handpiece.

The present disclosure relates to a saw, comprising a drive, a first blade configured to oscillate about an axis perpendicular to a plane defined by a surface of the first blade, a second blade configured to oscillate about an axis perpendicular to the plane in a direction opposite to that of the first blade, and wherein gearing is provided between the drive and the first and second blades to reduce the speed transmitted from the drive to the blades. A saw blade, a connection mechanism for connecting a blade to a saw and associated methods are also provided.
