The first letter generally indicates the shape of CNC inserts. The commonly used ones are H, O, P, S, T, C, D and E, which are regular hexagon, regular octagon, regular pentagon, square, diamond 80 degree top angle, diamond 55 degree top angle and diamond 75 degree top angle respectively.

There are 6 numbers in total, which are divided into three groups. The first group represents the tungsten inserts edge length, the second group represents the blade thickness, and the third group represents the arc radius of the blade tip.

The following letters indicate the material of carbide cutter. There are many materials of carbide inserts, and the products produced from different materials will naturally be different. Therefore, when purchasing NC blades, we must pay attention to the material of blades, and the prices of different materials are completely different.

There are many CNC carbide inserts of various shapes, uses and materials. First, let's understand the classification of cemented carbide insert turning tools.

Generally, the carbide cutter inserts model is represented by 10 numbers. In this model, the first four letters represent the characteristics of the lathe inserts, and the next six numbers represent the size and model characteristics of the carbide cutter.

The third letter indicates the accuracy grade of the carbide tool inserts. The most commonly used are grade m and grade g. generally, the rough machining and semi finishing finishing blades are grade m, and the precision machining blades and superhard blades are generally grade G.

The second letter obviously represents the blade rear angle. The commonly used letters are usually a, B, C, D, E, F, G and O. a represents the rear angle of 3 °, B is 5 °, C is 7 °, D is 15 °, E is 20 °, F is 25 °, G is 30 °, N is 0 °, P is 11 °, and O represents other rear angles.

Generally, it is represented by two letters, mostly alloy, P represents general steel, M represents stainless steel, K represents gray cast iron or nodular cast iron, N represents aluminum / scrap metal, S represents heat-resistant alloy or titanium alloy, H represents high hardness material, etc.

DNMG150408-MS is a turning tool inserts. D represents 55°diamond blade, N represents 0°rear angle of blade, M represents accuracy grade of blade manufacturing, G represents front edge surface and central hole type, 15 represents cutting edge length, value is 15mm, 04 represents blade thickness of 4.76mm, and 08 represents arc radius of tool tip of 0.8mm.
