ANORDNING FOR MANUELL AVGRADNING

The invention relates to a manual deburring tool having a handle, a scraper blade and a blade-holder attached to the handle, and having a longitudinal bore into which a circular shank of the blade is rotatably inserted. To enable the tool to be used for working on internal edges as well as external edges, the blade-holder has a transverse bore which intersects the longitudinal bore and into which the shank of the blade is alternatively rotatably insertable. A releasable locking device is provided in the region of the intersection of the bores for holding the blade in the selected bore. The releasable locking device is in the form of a spring biased sleeve which normally holds a spherical detent member in engagement with a peripheral groove on the blade shank whether the blade shank is inserted in the longitudinal bore or the transverse bore. The blade-holder is itself releasably located in an adjusted position in the handle.
