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

Heavy-Duty MSBNR/L 75° Tool Holder for DNMG Series

The MSBNR/L tool holder is specifically designed for high-removal rate operations where edge strength is critical. Its 75-degree lead angle makes it an exceptional indexable turning tool holder for heavy roughing. Whether your setup requires a standard external tool or a specialized dnmg neutral tool holder configuration for specific profiles, the MSBNR/L provides the necessary rigidity for high-feed lathe turning tool holder applications.

Optimized for DNMG 432 and Professional Inserts

This series is precision-crafted to accommodate 55-degree diamond inserts. The reinforced pocket design makes it a superior dnmg insert holder for various heavy-duty tasks:

• DNMG Inserts: The primary choice for general steel and alloy turning, often used as a standard dnmg holder.

• DNMA Inserts: Ideal for machining cast iron, providing the flat-top stability required for brittle materials.

• DNMM Inserts: The top choice for interrupted cuts and high-feed roughing within the lathe insert holder category.

Rigid M-Type Multi-Lock Clamping System

The MSBNR/L features the industrial-standard M-type clamping mechanism. Unlike a basic dnmg tool holder, this system locks the insert via both a top clamp and a center pin. This double-locking action is vital for 75° turning, preventing the insert from shifting under the significant cutting pressure found in tool holder for turning operations.

Q: When should I use the MSBNR/L instead of a 95° MDUNR?
A: Use the MSBNR/L when heavy roughing is the priority. The 75-degree angle is much stronger than a 95-degree angle, allowing for higher feed rates and better heat dissipation. It is the best dnmg holder choice for removing large amounts of material quickly.

Q: Can this holder be used for profiling?
A: While its 75° angle is great for longitudinal turning, it is not as versatile for intricate profiling as a dnmg neutral tool holder or a 93° holder. It is primarily a high-strength turning tool holder for straight cuts and 15-degree chamfers.

Q: Does the M-type clamp support all dnmg insert holder variations?
A: Yes, the M-type multi-lock system is designed to be compatible with all ISO-standard DNMG geometries. It ensures your dnmg tool holder setup remains vibration-free, which is essential for preserving the life of expensive carbide inserts.
