Abstract: A device for attaching a tool in portable angled grinders, allowing the connection to be released without special accessories. The device consists essentially of a hollow driveshaft, of a spindle that slides inside it, and of a tool-securing point consisting of a mating flange and nut. The nut is loosened by activating the displacing mechanism, which displaces the spindle toward the tool-securing point, lifting the nut, which is connected to the spindle by means of a threaded pin, off of the tool. The nut can then be screwed off by hand.

Abstract: A protective-hood fastening for portable angled grinders is disclosed. The protective hood is attached by a tensioning strap and screw to, and can be released from, a spindle collar on the gear housing. A securing element prevents the hood from slipping off the housing and into the grinding disk.

Abstract: A cutting tool for separating beads of adhesive, with a U-shaped cross-section consisting of two flanks connected by a web. One flank is a sickle-shaped blade and the other is employed to attach the tool to an oscillating driveshaft. The center of curvature of the sickle shape extends toward the point at which the cutting tool is secured. The web between the tensioning shank and the blade may have ridges. These ridges extend to the sides of the tensioning shank and blade. The web is longitudinally curved between the tensioning shank and the blade, and has round edges.
