The SD TRD line contains solid carbide heads with 10 effective teeth for a 40 mm
(1.563 inch) cutting head diameter and 8 effective teeth for a 32 mm (1.248 inch) cutting
head diameter. This line enables a reduction in cutting time by increasing feed due to the
large number of effective teeth. The cutter heads feature an internal spline mounted on
a matching external spline on the shank, secured by a central screw. SD TRD heads are
used for machining external and internal threads with different overhangs depending on the
selected shank. This line offers a solution for partial profiles of 55° and 60°.
