High-Removal MSRNR/L 75° Tooling for Industrial Lathes
The MSRNR/L tool holder is built for the most demanding CNC turning tool holder types. By utilizing a 75-degree approach angle, this tool directs cutting forces more axially into the spindle, reducing the risk of workpiece deflection. While many operators look for a dnmg neutral tool holder for profiling, the MSRNR/L is the preferred choice for powerful longitudinal cuts where stability is the absolute priority in a lathe turning tool holder.
Strategic Versatility with DN-Series Inserts
This dnmg insert holder is precision-machined to ensure a high-tolerance fit, preventing the vibration that often leads to carbide failure. It is fully compatible with:
-
DNMG Inserts: Perfect for multi-purpose turning on steel and stainless steel.
-
DNMA Inserts: The ideal match for cast iron processing where flat-base stability is required in a dnmg holder.
-
DNMM Inserts: Reinforced geometries that excel in interrupted cutting and heavy-duty indexable turning tool holders applications.
Advanced M-Type Clamping for Superior Grip
The MSRNR/L utilizes a sophisticated M-type double-clamping system. By pulling the insert into the seat with both a top clamp and a rigid center pin, this tool holder for turning ensures the insert cannot lift during high-feed cycles. This locking mechanism is significantly more secure than a standard dnmg tool holder with a single-point screw, allowing for deeper cuts and faster cycle times.

FAQ (Professional Support)
Q: How does the MSRNR/L 75° angle improve productivity?
A: Unlike a 95° dnmg tool holder, the 75° angle of the MSRNR/L allows the load to be spread over a longer portion of the cutting edge. This promotes chip thinning and heat dissipation, letting you push higher feed rates without breaking your DNMG inserts.
Q: Can the MSRNR/L replace a dnmg neutral tool holder for general tasks?
A: The MSRNR/L is a directional (Handed) tool, whereas a dnmg neutral tool holder is centered. Use the MSRNR/L for heavy, one-directional roughing where maximum rigidity is needed; use a neutral holder for symmetrical profiling or chamfering.
Q: Is this dnmg insert holder compatible with different brands of inserts?
A: Yes. As long as the inserts follow the standard ISO/ANSI DNMG geometry (55° diamond), this dnmg holder will provide a perfect fit and high clamping security.
