The inserts are available in three lengths and two carbide grades, reportedly offering improved rigidity, precision, and compatibility with a range of tool holders.

The geometry can be used universally for different material groups and is suitable for internal, face, copy and back turning. In addition to the geometry, Horn optimised the carbide blanks of the inserts to have greater rigidity and an even more stable cutting-edge area.

Horn offers inserts in three different sizes (types 105, 109, and 110) and various blank types, depending on the application and the diameter to be machined. All types allow for internal coolant supply directly to the cutting zone.

Paul Horn GmbH, headquartered in Tubingen, Stuttgart, Germany has launched a new version of the Supermini type 105 solid carbide inserts. The new range offers a lower-cost alternative to the solid carbide inserts by including the chip-breaking geometry at the sintering stage, rather than using laser cutting or grinding afterwards.

Horn developed the carbide blanks for the tool as a teardrop shape. This enables large, precise contact surfaces in the tool holder, which results in greater rigidity of the overall system. Furthermore, the teardrop shape prevents the insert from twisting, which leads to consistently precise positioning of the centre height of the tool. With long tool overhangs, it reduces deflection and minimises vibration during turning.
