Horn’s Mini 114 system enables a face grooving depth of up to 10 mm. The insert is suitable for turning and copy turning of axial grooves. According to the company, the user does not need a special toolholder, as the insert is compatible with the existing axial holder system. As standard, Horn offers the EG55 carbide grade grooving tools in three different types from stock with cutting widths of 2 mm, 2.5 mm and 3 mm. The minimum diameter for grooving is 14 mm, while the maximum is 34-36 mm, depending on the type.

The face-screwed inserts of the Mini system are said to be one of Horn’s core products, and the tool system is well suited for turning and milling applications, as well as boring, internal grooving and face grooving. Paired with the low-vibration carbide toolholders, the inserts produce a good surface finish even with long overhangs and provide process reliability. The Mini system’s broad portfolio offers inserts in various sizes for different internal diameters, different geometries and substrates, as well as CBN or diamond tips.
