Raw Material Selection

Suitable materials such as tungsten carbide, ceramics, or high-speed steel are selected based on the blade’s application. These materials must offer high hardness and wear resistance.

Powder Metallurgy

Metal powders are mixed in precise ratios, pressed into shape, and then sintered at high temperatures to form blade blanks.

Imported Press Machine Forming

From importing presses to stamp out blade blanks, to subsequent sintering and coating, every step is strictly controlled, all to provide customers with stable and reliable blade solutions

Oswald Insert Pressing

Specifically designed for pressing various types of turning tool blanks, it enhances blade density and lifespan stability, ensuring more consistent batch dimensions and a more reliable cutting process.

Coating Application

The insert undergoes precision grinding and cleaning before being subjected to PVD/CVD vacuum coating, forming a multi-layered hard coating structure that combines high hardness, wear resistance, and stable lifespan.

Edge Preparation & Passivation

The insert edge is finely passivated to remove small dents and burrs, improve the strength and stability of the insert edge, and thus extend the service life of the insert.

Packaging & Shipping

At HNCarbide, every shipment of DNMG carbide inserts is carefully packaged to ensure your tools arrive intact.
Each DNMG insert is placed in a shock-resistant case, labeled with full DNMG insert specifications and DNMG insert size, then sealed in moisture-proof material before boxing.
Large-volume orders of carbide DNMG inserts are further reinforced with double-wall cartons or wooden crates for safe international transport.
We work with trusted logistics partners to ensure your DNMG inserts are delivered quickly and securely by air freight, sea freight, or express courier.

FAQ

A DNMG insert is a 55° diamond-shaped, double-sided turning insert used for medium to finishing CNC turning.
The code DNMG stands for:

  • D – 55° diamond shape

  • N – 0° relief angle

  • M – Tolerance class M

  • G – Double-sided insert with a chipbreaker

DNMG inserts are commonly used for precision profiles, copy turning, and finishing steel and stainless steel.

DNMG inserts have a 55° diamond angle, making them ideal for profiling and finishing.
Geometry options include:

  • Neutral (N) clearance

  • Sharp finishing chipbreakers (MF, PM, MS)

  • Strong roughing chipbreakers (RM, RR)

  • Wiper geometry (DNMG wiper insert) for improved surface roughness

This angle allows DNMG inserts to reach tight profiles CNMG inserts cannot.

DNMG inserts fit holders such as:

  • SDJCR / DDJNR / SDJCL turning holders

  • Indexable boring bar inserts (keywords: DNMG indexable boring bar insert 3/8 shank)

  • Neutral clamp systems

  • 55° insert pockets in ISO/ANSI toolholders

DNMG holders provide high stability in finishing operations.
