Abstract
An indexable insert is located on a toolholder with reference to bearing surfaces on the insert and the toolholder which are proximate to the active cutting edge. These bearing surfaces are internal to the peripheral (side) flanks of the insert. Location of the insert in the toolholder is substantially independent of the relation between the toolholder pocket sidewalls and the peripheral flanks of the insert, thereby eliminating sources of error from insert manufacture and pocket manufacture. The insert and toolholder have locating units disposed thereon adapted to matingly engage each other when the insert is placed in the toolholder. At least one of the locator elements has a bearing surface or surfaces that extends through 360° and resulting in less movement of the insert during use.
