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 pole sander is provided including an elongate body having a first end and a second end, an electric motor, and a sanding head attached via a pivot mechanism to the first end of the elongate body. The sanding head includes a hood including a plate and a peripheral wall formed on the underside of the plate around an edge of the plate; an output spindle that projects from the hood and is rotatably driven by the electric motor around a rotational axis; and a brush ring mounted on the underside of the plate adjacent the edge of the plate inside of the peripheral wall. The brush ring is attached to the plate via a spring comprising at least one of a leaf spring or a wave spring.

A pole sander is provided including an elongate body having a first end and a second end and forming a passageway, a sanding head attached via a pivot mechanism to the first end of the elongate body and including an output spindle projecting into a chamber, an electric motor mounted on the sanding head, and a rear housing mounted on or proximate the second end of the elongate body including control electronics therein to control the motor via an electric cable. At least a portion of the electric cable locates against a flexible pipe connecting the passageway to the sanding head.

A pole sander is provided including an elongate body including a passageway for passage of air, an electric motor, and a sanding head attached via a pivot mechanism to a first end of the elongate body. The sanding head includes a hood including a plate and a sidewall to form a chamber, an output spindle projecting from the hood and rotatably driven by the electric motor, and a tubular passage including a first end forming an opening and a second end coupled to an aperture formed through the plate. A flexible pipe is disposed between the passageway at the first end of the elongate body and the opening of the tubular passage to fluidly connect the passageway to the chamber. The tubular passage is oriented at least partially around a portion of the output spindle in a turning direction of the output spindle and extending angularly from the plate.

A pole sander is provided including an elongate body having a longitudinal axis, and a sanding head attached via a pivot mechanism to a first end of the elongate body. The sanding head includes a hood including a plate and a sidewall to form a chamber, an output spindle projecting through the hood into the chamber, and an electric motor mounted on the hood and configured to rotatably drive the output spindle about a rotational axis. The pivot mechanism allows the sanding head to pivot around a pivot axis that intersects the sanding head forward of at least one of a centre of gravity of the sanding head or the rotational axis of the output spindle relative to the elongate body when the longitudinal axis of the elongate body is located parallel to the plane of the plate.

A handheld pole sander is provided including an elongate body having two ends, the elongate body including a first pole and a second pole made partially of electrically conductive material and capable of sliding in and out of each other in a telescopic manner the first pole and second pole are made from electrically conductive material. An electric motor electrically controlled by control electronics is provided, and a sanding head is attached via a pivot mechanism to a first end of the elongate body. At least one seal is located between overlapping parts of the first pole and second pole. The seal includes an electrically conductive material and provides an electrical connection between the first pole and second pole. Alternatively, at least one electrical contact is provided between the first pole and second pole to provide an electrical connection between the first pole and second pole.

A power tool comprising: a conductive tube; a rear unit located at a rear end of the tube; a front unit located at a front end of the tube; a battery interface comprising a plurality of terminals, wherein the battery interface is located in the rear unit; a motor located in the front unit; at least one power line for supplying power from the rear unit to the front unit, wherein at least a portion of the power line is located within the tube; and an electromagnetic interference (EMI) suppressor for suppressing EMI from the at least one power line, the EMI suppressor comprising an electrical component electrically connecting the tube to a first terminal of the plurality of terminals.

A monopodic sander is provided for an operator to sand a surface. The monopodic sander comprises a rotary sanding head for contacting the surface and an extendable actuator rod having one end pivotally coupled to the rotary sanding head. The monopodic sander further comprises a controller handle operatively coupled to the one end of the extendable actuator rod to allow the operator to select a pressure applied by the rotary sanding head against the surface.

A stand up sander assembly for sanding a floor with a weed trimmer includes a cup that is mountable to a drive output of a weed trimmer such that the cup is rotated by the weed trimmer when the weed trimmer is turned on. A coupler is removably coupled to the cup. The coupler lies on a plane that is oriented perpendicular to a rotational axis of the drive output. A sanding disk is removably attached to the coupler. In this way the sanding disk can be positioned against a surface to be sanded when the weed trimmer is manipulated. The sanding disk is comprised of an abrasive material thereby facilitating the sanding disk to sand the surface.

A sliding ring for a grinding device consisting of a grinding element and a hood covering the grinding element and a sliding ring attachable to the side of the hood facing a surface to be machined, the sliding ring having a sliding surface provided for sliding on the surface to be machined, the sliding ring consisting of at least one elastic component and a sliding component, the sliding surface being formed on the sliding component and the elastic component being arranged on the side of the sliding component opposite the sliding surface.
