The CoroTurn 107 and CoroTurn 111 inserts can be supplied with four shank sizes of 12, 16, 20 and 25 mm with seats. Fine boring against a shoulder is enabled by bars which have entering angles of 90 and 92 degrees. The minimum clamping length (maximum overhang) is indicated on a scribed circle on shanks of 16, 20 and 25 mm.

One of the clamping screws is clamped directly on the surface of the sleeve when the sleeve is used. The other goes through the sleeve and clamps onto the bar's surface.
