The present disclosure provides a cutting device. The cutting device includes a shaft, two or more gussets, two or more radial cutting members, and a circumferential cutting member. The shaft extends from a first end to a second end. The two or more gussets include at least a first gusset and a second gusset extending radially away from the shaft. The two or more radial cutting members include at least a first radial cutting member axially supported by the first gusset and a second radial cutting member axially supported by the second gusset. The circumferential cutting member is axially supported by each of the first gusset and the second gusset.

In order to respond flexibly to various processing modes, such as forming curved surface shapes, when cutting a workpiece using a wire saw, this wire saw device (1) is provided with: a single robot arm (2) that is capable of moving freely by means of multi-axis control; a wire saw unit (3) that is detachably connected to the robot arm (2) via a tool changer (7); a wire (8) that spans a plurality of pulleys supported within the wire saw unit (3); and a workpiece cutting zone (20) that is established between the pulleys. The workpiece is cut to a prescribed shape by moving the robot arm (2) in a preset direction while running the wire (8) of the wire saw unit (3) and pressing the wire (8) against the supported workpiece.

A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

Disclosed is a punching assistant device. The punching assistant device includes: a first shaft arranged perpendicular to a working surface; a second shaft perpendicularly coupled to the first shaft; and a grinder mounting member coupled to the second shaft, wherein the grinder mounting member is rotatable around the first shaft.

A power tool for forming a channel in a work surface includes a first section carrying a rotatable shaft having a shaft axis and a second section that engages the work surface; a cutting disc having a substantially circular blade provided on the rotatable shaft; a first support portion on one side of the cutting disc and a second support portion on the opposite side of the cutting disc which cooperate to hold the cutting disc at an oblique angle relative to the shaft axis. A first locking feature of the first support portion and a second locking feature of the second support portion extend through a circular opening of the cutting disc and cooperate to resist relative rotation of the first and second support portions. The first section is movable relative to the second section to move the cutting disc into and out of engagement with the work surface.

A tile saw includes a saw with a cutting blade, a frame supporting the saw, a table supporting a workpiece and being slidable relative to the frame, and a rear fence secured to the table. The rear fence has an engagement surface and is adjustable between an operating position and a bypassed position. The bypassed position includes the engagement surface of the fence being no higher than even with the planar surface of the table to allow a workpiece to extend beyond a rear edge of the table. In the operating position, the engagement surface of the rear fence projects axially from the planar surface of the table to support the workpiece as the workpiece is pushed into the cutting blade during operation. The fence can be adjusted between the operating and bypassed positions by using any one of a cam lever clamp, pin and guideway, or rotatable latch.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.
