MSKNR/L Turning Tool Holder | 75° M-Type Indexable Tooling for DNMG Inserts

High-Stability MSKNR/L 75° Tool Holder for DNMG Series

The MSKNR/L tool holder is a specialized choice within the indexable turning tool holders category, designed for operations requiring high material removal rates. Its 75-degree lead angle provides superior edge strength compared to standard 95-degree holders. Whether you are setting up a standard longitudinal cut or comparing it against a dnmg neutral tool holder for specific profiling, the MSKNR/L offers the rigidity necessary for modern lathe turning tool holder applications.

Seamless Compatibility with DN-Series Inserts

This dnmg insert holder is precision-crafted to house 55-degree diamond inserts, allowing for versatile machining across various materials:

• DNMG Inserts: The primary choice for general steel and stainless steel turning, providing excellent chip control in this dnmg holder.

• DNMA Inserts: Ideal for cast iron (ISO K) machining, where a flat-top geometry ensures maximum clamping contact.

• DNMM Inserts: The reinforced choice for heavy-duty roughing and interrupted cuts, optimized for the high-feed capabilities of the MSKNR/L.

Rigid M-Type Multi-Lock Clamping System

Stability is the hallmark of a high-quality tool holder for turning. The MSKNR/L utilizes an industrial-grade M-type clamping mechanism that locks the insert with both a top clamp and a center pin. This double-locking action prevents the insert from shifting under the extreme cutting pressures found in heavy-duty lathe insert holder applications, ensuring consistent accuracy and a superior surface finish.

Q: Why should I choose a 75° MSKNR/L over a 95° dnmg tool holder?
A: The 75-degree angle on the MSKNR/L allows for a larger chip thinning effect, which protects the tool tip and allows for higher feed rates. It is the preferred dnmg holder for heavy roughing where a 90-degree shoulder is not required.

Q: Can the MSKNR/L be used as a dnmg neutral tool holder?
A: No, the MSKNR/L is a directional tool (Right or Left handed). For neutral applications requiring a balanced 45° or 62.5° angle, we recommend exploring our dnmg neutral tool holder series like the MSDNN or MDPNN.

Q: How does the M-type clamp enhance this dnmg insert holder?
A: In heavy 75-degree cutting, the insert faces significant pressure. The M-type “Multi-lock” system provides downward and pulling force simultaneously, ensuring the lathe insert holder remains stable, which is critical for preventing carbide chipping in high-volume tool holder for turning operations.
