MDPNN Turning Tool Holder | Neutral 62.5° M-Type Holder for DNMG, DNMA & DNMM Inserts

Professional MDPNN Neutral Tool Holder with 62.5° Lead Angle

The MDPNN tool holder represents a specialized category within CNC turning tool holder types. Its 62.5-degree approach angle is strategically engineered for operations where standard 93° holders might cause interference. As a neutral lathe turning tool holder, it allows for symmetrical cutting performance, making it the ideal choice for tapering, chamfering, and specific profiling geometries.

Multi-Insert Compatibility: DNMG, DNMA, and DNMM

One of the core strengths of the MDPNN series is its precision-machined pocket, which is designed to house various 55-degree diamond inserts. This dnmg tool holder is particularly effective when used with:

• DNMG Inserts (e.g., DNMG 432 tool holder compatibility): The most popular choice for general-purpose turning in steel and stainless steel.

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

• DNMM Inserts: Reinforced for heavy-duty roughing and handling interrupted cuts with high efficiency.

Maximum Stability with M-Type Double Clamping

To ensure precision in angular turning, the MDPNN utilizes a robust M-type clamping mechanism. This system secures the lathe insert holder via both a top clamp and a center pin. This dual-locking action provides significantly higher rigidity than standard screw-down systems, ensuring that your dnmg holder remains perfectly stationary under varied cutting pressures, resulting in an exceptional surface finish.

Q: What makes the 62.5° approach angle on the MDPNN unique?
A: The 62.5° angle is specifically designed to provide a balance between longitudinal turning and plunging. It allows for steeper chamfers and unique profiling paths that a standard dnmg tool holder with a 93° angle cannot achieve due to clearance limitations.

Q: Can I use this holder for heavy-duty roughing with DNMM inserts?
A: Yes. The M-type double-clamping system is built to handle the extreme cutting forces associated with DNMM inserts. It is much more secure than a simple lathe insert holder, preventing any micro-vibration during heavy-load tool holder for turning applications.

Q: Is the MDPNN suitable for both right-hand and left-hand operations?
A: Since the MDPNN is a neutral holder, it is mounted centrally. This makes it a highly flexible indexable turning tool holder, as it can be used for symmetrical tapering and multi-directional profiling in a single CNC program.
