Targeted chipbreaking

Paul Horn GmbH has extended the 108 and 114 Mini systems by adding a new GM threading geometry that is suitable for turning ISO metric internal threads in partial and full profile. The chipbreaker geometry enables the production of short chips, even with long-chipping materials and those that are difficult to machine. This reduces the risk of chip build-up and prevents swarf from becoming entangled around the tool holder, thereby increasing process reliability. Targeted chipbreaking also makes it easier to handle the chips. The 108 system is suitable for metric internal threads from a diameter of M10 with pitches of 0.5 to 1.25 mm (0.019" to 0.049"). Meanwhile, the 114 system is suitable for pitches of up to 2.5 mm (0.099"). The inserts are available in partial and full profile design. Standard turning tool holders from the Mini system may be used.

Mini type inserts screwed onto the face of the holder are among Horn`s core products. The tool system is suitable for turning and milling applications. The precision tools have particularly proven their worth for internal profiling and internal grooving applications. Thanks to the low-vibration carbide tool holders, the inserts produce excellent surface finishes even with longer throat depths and also ensure high process reliability. The extensive Mini system range offers inserts in a variety of sizes for various internal diameters, as well as different geometries and substrates and CBN or diamond tips.
