DNMG Insert Holder

A DNMG Insert Holder is a versatile turning tool holder specifically designed to securely clamp DNMG style indexable cutting inserts. The ISO designation “DNMG” indicates a rhombic-shaped insert with a 55-degree nose angle, a clearance angle, neutral cutting action, and a central mounting hole. These inserts are commonly used for a wide range of turning applications, including finishing, semi-finishing, and light roughing. Their 55-degree angle offers good accessibility and is particularly useful for profiling and creating complex shapes with less risk of interference compared to inserts with larger angles.

The primary function of a DNMG Insert Holder is to provide a stable and accurately positioned platform for the DNMG insert. This ensures precise material removal, excellent surface finishes, and good chip control. The holder features a precision-machined pocket that matches the specific shape and dimensions of the DNMG insert, allowing for secure and repeatable clamping, typically achieved with a screw or lever mechanism. This robust clamping prevents insert movement and vibration during machining, which is crucial for achieving high-quality results, especially in finishing passes and intricate profiling work.

DNMG inserts are favored for their versatility and ability to produce good surface finishes. They offer four cutting edges per insert (two on each side), providing good tool life and cost-effectiveness. The corresponding DNMG Insert Holders are designed for ease of use, enabling quick and straightforward insert changes, minimizing machine downtime. Available in various shank sizes and configurations to suit different machine tool types and application needs, DNMG Insert Tool Holders are a valuable asset in general turning and precision machining environments where good accessibility and versatile performance are required.
