The invention relates to a tool for burring holes, comprising a base body rotating around a rotational axis of the tool, said base body comprising a shaft which is used for clamping. Said tool also comprises at least one spring- elastic blade support which can be displaced with respect to the base body. The blade support comprises at least one cutting element which protrudes in a radial manner in relation to the rotational axis, said cutting element comprising at least one cutting front edge which is oriented at least partially in a transversal manner in the direction of cutting and which has improved burring qualities and increased stability with respect to prior art. This is achieved by virtue of the fact that the cutting element (8, 30, 31) is made of hard metal.
L'invention concerne un outil d'ébarbage d'alésages, comportant un corps de base tournant autour d'un axe de rotation de l'outil, présentant une tige de serrage, et au moins un porte-lame pouvant se déplacer de façon élastique par rapport au corps de base. Ledit porte-lame comporte au moins un élément de coupe faisant saillie radialement par rapport à l'axe de rotation, présentant au moins un bord avant, au moins partiellement orienté perpendiculairement par rapport au sens de coupe. L'invention vise à mettre en oeuvre un tel outil d'ébarbage présentant un meilleur pouvoir d'ébarbage et une plus grande résistance. A cet effet, l'élément de coupe (8, 30, 31) est réalisé en métal dur.
