A disc sander includes a rotary disc on which an abrasive paper is adhered for grinding workpieces. The abrasive paper is replaced by dismantling and replacing a new rotary disc adhered with a new abrasive paper without the need of peeling off the to-be-replaced abrasive paper. The disc sander includes a guard, which is moveable between a sheltered position where the guard covers around a periphery of the rotary disc to ensure the user's safety, and an unsheltered position where the rotary disc is not covered by the guard and accessible by the user, such that the user can conveniently dismantle the rotary disc from an output shaft of a motor and then install a new rotary disc, on which an abrasive paper having required roughness is adhered, on the output shaft.

A cutting apparatus includes: a processing feeding unit that performs processing feeding of a chuck table adapted to hold a workpiece; and two cutting units in which rotational axes of two spindles coincide with each other and cutting blades mounted to the spindles face each other. Each cutting unit includes a flange mechanism in which the cutting blade having a cutting edge fixed to an outer peripheral edge of a one-side outer surface of a circular disk-shaped base is fixed to the spindle. The flange mechanism is fixed to a tip of the spindle, sucks an other-side outer surface of the base of the cutting blade, and fixes the cutting blade to the spindle with the one-side outer surface of the base exposed to the side of the tip of the spindle, and the one-side outer surfaces of the cutting blades fixed to the two cutting units.

An angle grinder dust collection shroud includes mounting brackets which are attached to a shroud body via slots which allow the mounting brackets to move to different circumferential locations around the output shaft of the angle grinder as well and inwardly towards and outwardly away from the output shaft of the angle grinder. The mounting brackets are adjustable in their position around the angle grinder output shaft to allow them to engage the angle grinder while avoiding any mounting features for the angle grinder's stock blade guard.

A wheel grinder contains: a body, a work table, a vertical limitation frame, a movable adjustment portion configured to move vertically, a grinding wheel portion extending outward from the movable adjustment portion, and a motor fixed on the movable adjustment portion. The vertical limitation frame has two fixing holders, two mountings, and two first screw rods and two second screw rods which are inserted through the two mountings respectively and abut against a bottom of the movable adjustment portion. In addition, a stop cover is covered on the grinding wheel portion and includes a defining plate configured to define a connection shaft and an opening inside the defining plate.

A handheld pole sander is provided including an elongate body having two ends, an electric motor electrically controlled by control electronics, and a sanding head attached via a pivot mechanism to a first end of the elongate body. The sanding head includes a hood and an output spindle projecting from the hood and rotatably driven by the electric motor. At least part of the elongate body includes a heat conductive part being at least partially made of heat conductive material. The control electronics are mounted on the elongate body adjacent to or in direct contact with the heat conductive part of the elongate body.

A transmission arrangement (113) comprising a first axle (24) that is rotatable about a first axis (33) and is connected to a first pulley (25) that is arranged to drive an endless power transferring means (26) that further is adapted to drive a second pulley (27) that is rotatable about a second axis (34), where the transmission arrangement (113) comprises a first idle pulley (101) and a second idle pulley (102) which both are adapted to guide the endless power transferring means (26), where the first idle pulley (101) is rotatable around a first idle pulley axis (103) and the second idle pulley (102) is rotatable around a second idle pulley axis (104), where the distance between the idle pulley axes (103, 104) is fixed and where the idle pulley axes (103, 104) are pivotable around a common pivot axis (105), wherein the first pulley (25) is positioned between the idle pulleys (101, 102) and the second pulley (27) such that a distance between any one of the idle pulley axes (103, 104) and the second axis (34) exceeds a distance between any one of the idle pulley axes (103,104) and the first axis (33).
