Description

MUR Miniature Cutting Insert, Solid Carbide Mini Boring Bar

The MUR miniature cutting insert is the precise solution for 90° face turning and profile turning in confined bores and internal contours from a diameter of just 3.1 mm. Thanks to its specially ground cutting edge with a 90° front face, the MUR enables exact face machining – for example, when preparing sealing faces, seating surfaces, or precision grooves.

Manufactured from ultra-fine-grain solid carbide and coated with a high-performance multilayer coating (AlTiN/TiSiN), this tool ensures outstanding wear resistance, thermal stability, and process reliability – even when machining difficult materials.

The geometry with a 22° rake angle provides efficient chip formation and evacuation with low cutting forces – ideal for machining delicate components with tight tolerances. Whether in series production or single-part manufacturing, the MUR delivers consistent quality and minimizes rework.

MUR – the specialist for precise face turning in the smallest bores. Technically advanced, compact, and process reliable.

Mikro 90 Grad Plandrehen im Bohrungsgrund

Der MUR-Schneideinsatz schafft 90-Grad-Plandrehen in engen Bohrungen, auch bei dünnen Wänden bleibt die Kontur stabil und der Einsatz klemmt sauber.

Mini-Bohrstange MUR läuft

Die Miniatur-Bohrstange innenbearbeitung im sehr kleinen Durchmesser klappt mit dem Mikrohalter sauber, VHM-Schaft ist steif genug. Konnte meinen Prozess damit gleichmäßig halten.

90°-Innenplandrehen klappt

Die Geometrie des Schneideinsatzes erlaubt mir saubere Plandurchgänge in engen Bohrungen, die sonst nicht erreichbar wären. Die Schneide hält, die Maße passen und im Bereich der Werkzeugbau-Sondergeometrien eine wertvolle Ergänzung.

Mikro-Einsatz bewährt

Präzise gefertigt, Schneide sitzt sauber. Für Spezialanfragen mit feinen Details hervorragend geeignet. Bisher ohne Bruch.

Mini-Bohrstange steif auch bei Auskragung

Kleine Innendurchmesser kein Problem, die Bohrstange ist steif genug auch bei normaler Auskragung.

Mini-Bearbeitung passt bei mir sehr gut

Kleinste Innenkonturen gelingen sauber, keine Ausbrüche. Für Medizinteile ideal geeignet und der Sitz ist spielfrei. Die Lieferung kam zügig an und für den Preis ein runder Kauf.

Ordentlich im Einsatz

Der MUR-Einsatz macht einen guten Eindruck. Bisher nur wenige Teile damit gemacht, aber Ergebnis ist sauber. Muss sich im Dauereinsatz noch beweisen.
