Horn Supermini HP Eliminates Need for Multiple Tools

Horn’s Supermini HP has a cutting geometry suitable for drilling, boring, face and OD turning that enables higher cutting parameters, including feed rates. When boring, this results in an accurate 90-degree face at the bottom of the bore and OD shoulder. The wiper geometry produces high surface finishes, even at high feed rates.

In addition to turning operations, the company says the system is suitable for drilling into solid material at diameters ranging from 3 mm [0.118"] to 7 mm [0.276"]. The HP is not meant to replace standard high-performance drills, but rather to improve productivity by eliminating the requirement of multiple tool positions. The Supermini HP offers the option of boring an interior contour after drilling, without needing to change the tool. The single-edged version can produce various bore diameters.

The design of the holder system for the Supermini type 105 utilizes a tension wedge on the face rather than a retention screw on the circumference. This enables the cutting insert to be held in place with more force, which, in turn, makes the entire system more rigid. The new clamping design results in a higher level of repeatability when changing inserts and makes better use of available workspace. The company says this is a significant advantage when working with Swiss­type lathes, as it enables users to change the insert without removing the tool holder.
