Title
(EN) ABRASIVE ROTARY TOOL
(FR) OUTIL ROTATIF ABRASIF
Abstract
(EN)
The disclosure provides abrasive rotary tools with enhanced adhesion of an abrasive layer. Exemplary abrasive rotary tools include a securing element configured to secure an abrasive layer to an abrasive rotary tool. The securing element may be positioned over a portion of the abrasive layer, such as a tab or end, such that repeated forces on the abrasive layer do not decouple the abrasive layer from the rotary tool. In this way, an abrasive rotary tool may maintain a contact surface integrity through repeated use for extended life of the rotary tool.
(FR)
L'invention concerne des outils rotatifs abrasifs caractérisés par une adhérence renforcée d'une couche abrasive. Des outils rotatifs abrasifs décrits à titre d'exemple comprennent un élément de fixation configuré pour fixer une couche abrasive à un outil rotatif abrasif. L'élément de fixation peut être positionné par-dessus une partie de la couche abrasive, telle qu'une languette ou une extrémité, de telle façon que des efforts répétés sur la couche abrasive ne découplent pas la couche abrasive de l'outil rotatif. De cette façon, un outil rotatif abrasif peut maintenir l'intégrité d'une surface de contact au cours d'un usage répété pour une durée de vie prolongée de l'outil rotatif.
