ABSTRACT:
A turning tool includes a holder and an cutting insert clamped to the holder. The insert and the holder include respective support surfaces pressed against one another. Each of those support surfaces includes first and second sets of ridges oriented substantially perpendicular to one another. The ridges on the insert's support surface engage respective ridges on the holders support surface to prevent movement of the insert relative to the holder in two directions oriented perpendicularly to one another. At least one of the first and second support surfaces has its first and second sets of ridges arranged in respective first and second regions of that support surface. The other support surface could have its sets of ridges arranged in a similar fashion, or its sets of ridges could occupy the same region of the support surface to form a waffle pattern.
