Description

CNMG-M3 Indexable Carbide Inserts for Stainless Steel

The CNMG-M3 indexable insert in grade TT2225 is the robust and universally applicable solution for machining stainless steel, ranging from roughing to semi-finishing. Its state-of-the-art AlTiSi-based nanocomposite PVD coating combines extreme hardness, strong oxidation resistance, and excellent thermal stability, ensuring consistently reliable performance even at high cutting speeds.

The very low coefficient of friction reduces built-up edge formation, resulting in stable chip flow and improved surface quality. The specially developed M3 chipbreaker ensures controlled chip breaking and secure chip evacuation, even under higher cutting forces. Grade TT2225 provides a balanced ratio of wear resistance and toughness, making the CNMG-M3 extremely process-secure even in interrupted cuts.

The tough substrate ensures maximum fracture resistance and long tool life, reducing tool changes and significantly lowering part costs. With its stable cutting edge performance, the CNMG-M3 is the ideal choice for users seeking a reliable, economical, and durable insert for stainless steel machining.

Sehr empfehlenswert

Solide Qualität, nichts zu meckern. Hab es auf der Traub TNL 12 im Einsatz. Kein Aufbauen an der Schneide. Spanbruch passt bei mir gut. Gerne wieder.

CNMG-M3 sehr robust im Edelstahl

Die Platten bewähren sich auf unserer Haas ST-30 beim Drehen von größeren 1.4404-Werkzeugaufnahmen ausgezeichnet. Die Spankontrolle ist selbst bei zähen Edelstählen gegeben, die Kanten halten lange und die Oberflächen sind auch bei höherer Zustellung sehr gleichmäßig. Für den Preis eine deutliche Empfehlung. Standzeit ist bemerkenswert.

M3-Sorte im Edelstahl-Alltag

Rhombische Platten in universeller M3-Sorte. Bei unseren gemischten Edelstahl-Aufträgen im Lohnbetrieb die erste Wahl. Auch bei kräftigeren Zustellungen bleibt die Platte stabil im Schnitt.
