MDJNR2525M15 Turning Tool Holder For DNMG 1506 inserts

The MDJNR2525M15 Turning Tool Holder is a robust external toolholder designed for DNMG 1506 negative inserts. With its 25×25 mm shank, the MDJNR2525M15 Turning Tool Holder provides high rigidity and secure clamping, making it ideal for medium to heavy-duty machining. Built with a lever-lock clamping system, the MDJNR2525M15 Turning Tool Holder ensures stable insert positioning, reduced vibration, and long-lasting accuracy in turning operations.

This holder supports DNMG 1506 inserts, which offer a thicker geometry than the 1504 series, enabling deeper depth of cut and stronger edge support. The negative rake pocket design allows multiple cutting edges per insert, maximizing tool life and reducing machining costs. With its 93° approach angle, the MDJNR2525M15 is versatile for external turning and facing, especially in steels, stainless steels, and cast irons.

Engineered for performance and reliability, it is widely applied in automotive, aerospace, and heavy engineering industries. The toolholder’s rigid construction makes it suitable for both continuous and interrupted cutting, ensuring consistent performance under demanding conditions.
