Stem for a power tool attachment

Small, portable power tool

An apparatus for making a surface treating article, and in one embodment for making a plurality of surface treating articles. The apparatus includes an attaching means for attaching a fastener to a surface treating web and a cutting means for cutting the web around the fastener to provide a surface treating article. In one embodiment, a sensor, such as a machine vision system, senses a position of the fastener on the web, with this sensed position being used to direct operation of the cutting means.

Apparatus for making a surface treating article

An attachable abrasive article comprises an abrasive member having an attachment device affixed thereto. The attachment device comprises a fastener having a flange thereon. Thermoplastic material is disposed between the flange and the abrasive article. The disclosure also concerns methods of making and using attachable abrasive articles.

Abrasive articles, and methods of making and using the same

Abrasive article including a backing plate. Backing plate has a first major surface and a second opposite major surface. A central aperture extends through backing plate. An abrasive layer is secured to the first major surface of backing plate. A fastener is press fit to backing plate so as to define the central aperture.

Abrasive article

A surface treating article including a surface treating member and a fastener including a fiducial. The present invention also provides a preferred method of making a surface treating article that includes to a method of sensing the location of a fasteners on a surface treating web and thereafter cutting the surface treating web around the fastener to provide a surface treating article.

Method of making a surface treating article and such a surface treating article

A holder for an abrasive disc allows for a quick manual change of the abrasive disc. The holder including an uncoupling mechanism that in turn includes a handle comprising a pin and an adjacent hub comprising a partial annular channel. The handle and hub have a limited rotational engagement wherein the pin travels in the channel. When an operator desires to replace an abrasive disc, the operator grasps the handle with one hand and rotates the disc, face plate, and hub, together as a unit, with the other hand. This counter-rotation breaks the tight attachment of the disc on the shaft of the finishing tool, so that disc can be easily unthreaded from the shaft.
