BT/BTA: internal (UT – UTS) and external (UTE DX – UTE SX) insert-holder

2) Holder for internal splines (UTS) (pic. 1)

This model (UTS) has the same sizes and features of the holder UT for internal keyway machining, with a special insert seat, where the special insert for spline is installed.  This means that model UTS is a standard holder and thus always available in stock. Inserts for internal spline, which must follow specific standards, remain special, and for this reason produces on Customer’s request.

For instance, the item code UT-4-25 identifies the holder for 4 mm insert with the standard L1=40 mm, while the item code UT-4-25L identifies the long version of the holder, with a L1=56 mm.

*** Only for item UT-10-25 and UT-12-25 short version (not the long version), L3 size is 11 mm and not 9 mm.
