CoroCut® 1-2

Versatile parting and grooving

With more than 700 standard inserts, CoroCut 1-2 covers all parting and grooving applications in most materials, from standardized grooves to parting off and profiling in heat resistant super alloys.

Cost efficiency with two edges

The two-edge inserts are firmly positioned in the railed insert seat giving cost-efficiency and stable performance.

Secure and efficient machining

In grooving, chips easily get stuck in the curved groove, leading to insert breakage. CoroCut 1-2 tools with precision coolant securely evacuate the chips for an undisrupted machining process.

Tournage dur avec CoroCut 1-2

La nouvelle géométrie -XB autorise des très grandes avances pouvant atteindre 1.2 mm/tr (0.0047 pouce/tr) sans compromettre la qualité des états de surface.

Accessibilité avec les plaquettes angulaires

Les plaquettes angulaires sont idéales pour les gorges difficiles d'accès comme, par exemple, dans les disques de turbines ; elles peuvent remplacer les outils spéciaux.
