Redesigned Insert Clamp Improves Rigidity
The toolholder for Horn USA’s Supermini grooving and boring tools applies a tensioning wedge to the insert’s face rather than circumference, increasing rigidity and repeatability.

Horn USA Inc. (Franklin, TN) has developed a toolholder for its Supermini 105 grooving and boring tools. In the new design, the process for clamping the carbide insert uses a tensioning wedge on the face rather than the circumference of the tool, as was previously the case. This enables the insert to be held in place with more force, which in turn makes the entire system more rigid.
Additionally, the design produces a higher level of repeatability when changing inserts and allows better use to be made of the space available for mounting, thanks to the face-clamping concept. This is a significant advantage when working with Swiss-type lathes because it enables operators to change the insert without removing the toolholder.
The Supermini tool system bores holes from 0.2 mm to 8 mm in diameter. With over 1,500 varieties available as standard, there’s a solution to suit every user. In addition to boring, the system is designed for grooving, chamfering, threading, broaching and other machining operations. Cutting geometries and substrates can be adapted to the material being machined.
