BT/BTA: insert holder for internal square and hexagonal profiles (UT-SQ / UT-HEX)
The insert holder is made in hardened and quenched steel: these treatments assure a great resistance to compression.
For particularly hard materials (HRC> 30) we can supply inserts and insert holders to make squares of smaller dimensions.
