Just tell us which carbide inserts you are looking for and our team will help you hold the palm.
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.
Metal powders are mixed in precise ratios, pressed into shape, and then sintered at high temperatures to form blade blanks.
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
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.
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.
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.
At HNCarbide, every shipment of CNMG carbide inserts is carefully packaged to ensure your tools arrive intact.
Each CNMG insert is placed in a shock-resistant case, labeled with full CNMG insert specifications and CNMG insert size, then sealed in moisture-proof material before boxing.
Large-volume orders of carbide CNMG inserts are further reinforced with double-wall cartons or wooden crates for safe international transport.
We work with trusted logistics partners to ensure your CNMG inserts are delivered quickly and securely by air freight, sea freight, or express courier.
A CNMG insert is a double-sided, 80° diamond-shaped turning insert used for roughing and finishing of steel, stainless steel, cast iron, and alloy materials.
The code CNMG stands for:
C – 80° diamond shape
N – 0° clearance angle
M – Tolerance class M
G – Double-sided with 4 cutting edges per side (8 edges total)
Common CNMG sizes include 1204, 120408, 1906, 431, 432, 543, 643
Choosing the correct CNMG insert depends on material and grade:
CNMG 1204 / 432 with general-purpose CVD-coated grades
Roughing → Strong chipbreaker like RM, RR, MM
Finishing → Sharp geometry like MP, PM
Positive-action chipbreaker such as MS, MF
Wear-resistant PVD grades for low cutting forces
Polished uncoated carbide CNMG inserts
Sharp cutting edge and high rake angle
(You had keywords like “cnmg insert for aluminum Mitsubishi”)
CBN CNMG inserts（cnmg cbn insert, hardened steel）
Ceramic CNMG inserts for ultra-high hardness materials
PVD-coated, heat-resistant grades
Stable geometry (e.g., 432-MA, 432-TF types)
CNMG inserts follow ISO and ANSI sizing standards. Popular models include:
CNMG 1204 / 120408 → General-purpose steel turning
CNMG 431 / 432 → Inch-standard inserts for US market
CNMG 543 / 643 → Larger, heavier inserts for high-load machining
CNMG 1906 → Special-size inserts for heavy roughing
CNMG 1204-TM, 120408-TM → Chipbreaker-specific variants
CNMG 432-TF / 432-MP / 432-MA → OEM geometry styles
