ABSTRACT:
An expandable abrasive tool is provided with an axially-extending slot receiving a single abrasive element and multiple axially aligned and axially spaced apart pockets located circumferentially from the slot with each pocket fixedly receiving an individual centering element for properly positioning and supporting the abrasive element in the hole. The axially spaced apart pockets space the centering elements apart in end-to-end relation and thereby allow torsional flexing of the tool body during hole machining without damaging the brittle centering elements. In an alternative version, multiple centering elements are received in spaced apart end-to-end relation in a single axially elongated slot instead of in individual pockets.
