MDUNR/L 旋削工具ホルダー | DNMGインサート用95° Mタイプインデックス式工具

Versatile MDUNR/L 95° Tool Holder for DNMG Series

The MDUNR/L tool holder is one of the most popular choices among indexable turning tool holders. Its 95-degree lead angle allows for both longitudinal turning and facing operations in a single setup. Whether you are searching for a high-performance dnmg tool holder or a specialized dnmg neutral tool holder configuration, the MDUNR/L provides the rigidity needed for consistent accuracy in a high-production lathe turning tool holder environment.

Compatible with the Full Range of DN-Series Inserts

This series is engineered to provide a seamless fit for 55-degree diamond inserts. The precision pocket design makes it a reliable dnmg insert holder for various applications:

• DNMGインサート： The standard for general steel, stainless steel, and alloy turning.

• DNMAインサート: Ideal for machining cast iron (ISO K) where a flat-top, hole-clamping design is required.

• DNMMインサート： Featuring reinforced edges for heavy-duty roughing within the lathe insert holder category.

H3: Robust M-Type Double Clamping Mechanism

The hallmark of the MDUNR/L is its M-type clamping system. Unlike a standard dnmg holder, this “Multi-lock” design secures the insert with both a top clamp and a center pin. This double-locking action is essential for preventing micro-vibrations during heavy cuts, ensuring that your tool holder for turning remains stable and extends the life of your carbide inserts.

Q: Why choose a 95° MDUNR/L over other DNMG tool holder types?
A: The 95-degree angle is highly versatile for general turning. It provides enough clearance for facing while maintaining strong support for the DNMG insert cutting edge. It is a more robust dnmg holder for straight turning compared to profiling-specific holders.

Q: Can this holder be used as a dnmg neutral tool holder?
A: While the MDUNR/L is specifically right or left-handed, its 95° angle allows for neutral-like performance in specific facing and longitudinal paths. For a true dnmg neutral tool holder, we recommend the MDPNN or MCMNN series.

Q: How does the M-type clamp benefit a dnmg insert holder?
A: The M-type system pulls the insert down and back into the pocket. This ensures that the lathe insert holder remains rigid even during interrupted cuts, significantly reducing the chance of insert breakage compared to screw-only systems.
