A hand held orbital sander has a housing having an electronically commutated motor disposed therein and an orbit mechanism disposed beneath the housing. A motor controller is coupled to the motor. The motor controller changes the speed of at which it runs the motor from an idle speed to a sanding speed upon the motor speed dropping from idle speed to an idle speed threshold value and changes the speed at which it runs the motor from sanding speed to idle speed upon the motor speed increasing from sanding speed to a sanding speed threshold value. The sander may have a mechanical brake that brakes the orbit mechanism and the motor controller also dynamically brakes the motor.

The manufacture method of the invention can be used for manufacturing the compound steel plate of stainless steel with a total thickness of 0.8mm to 2mm.

A random orbital sander including a housing, a motor having a vertical axis in the housing, a pad coupled to the motor, a face on the pad extending substantially perpendicularly to the vertical axis, a shroud surrounding the pad, an opening in the shroud, and a dust discharge tube having an inner end in communication with the opening and an outer end on the dust discharge tube end extending at an acute angle to the face of the pad. An orbital sander wherein the pad is supported from the sander housing by columnar units located on opposite sides of the motor. A bore in the motor shaft conducts compressed air through the chamber housing the bearings which support the spindle which mounts the pad.

A motor driven power tool is provided having an internal dust collection system. A single electric motor drives the working member such as a saw or sander and simultaneously drives an air pump which acts as a collector vacuum for debris created when the power tool is in use. A dust collector shroud surrounds a portion of the cutting member and forms an outlet connected to the air pump inlet.

An Advanced Burnishing Tool for burnishing Venetian plaster surfaces comprises a base with a working surface with a plurality of concentric ribs. The tool may be used manually or may be mounted on a power tool such as an oscillating sander. Each rib has a rounded upper portion for contacting the surface, so that each rib acts in a manner similar to the rounded edge of conventional burnishing tools. The plurality of ribs provide a simultaneous working of multiple points in the plaster surface. Efficiency is further improved when a power tool is used to reduce the manual effort required for burnishing.
