Solid carbide miniature cutting inserts | Solid carbide mini boring bars
Discover our highly specialized range of miniature cutting inserts made of solid carbide (VHM) – developed for maximum precision and process reliability when machining the smallest bores from Ø 2.1 mm. The mini boring bars impress with excellent stability, finely ground cutting geometries, and state-of-the-art multilayer coatings (AlTiN, TiSiN) that ensure maximum tool life even under thermally and mechanically demanding conditions.
Our tooling portfolio covers all applications in micromachining:
Boring, profile turning, copy turning, grooving, full-radius grooving, axial grooving, thread turning (partial profile), chamfering, and 90° face turning – for all common materials such as steel, stainless steel, cast iron, aluminum, copper alloys, heat-resistant superalloys, and hardened steels up to 55 HRC.
Thanks to their compact and low-vibration design, the miniature cutting inserts are ideal for use on sliding headstock lathes, micro turning centers, and CNC machines with limited workspace. Typical fields of application include medical technology, precision engineering, watchmaking, aerospace, and electronics manufacturing.
