The packaging of carbide inserts usually have a lot of information, including the brand logo, insert model, grade, work piece（PMKNSH） recommendation, cutting parameters references…What does this information on the package mean? Let’s take a look at how to distinguish this information.

CNC inserts can be divided into metric (ISO) and inch (ANSI) standards. The main difference lies in the number in the middle. In addition, different tools have different expressions.For example ISO: CNMG120408PS, ABSI: CNMG432PS

The hardness of cemented carbides can be divided into ferrite, pearlite gray cast iron, nodular cast iron, pearlitic ferrite malleable cast iron.

Class H refers to the cutting hardness range of blade in hardened steel, Cast Chilled Cast Iron, hardened cast iron, etc.

Class n refers to uncured aluminum, refined alloy, casting alloy, copper alloy including easy cutting steel, brass, electrolytic copper.

The insert grade is not standard like the tungsten carbide raw material, such as K10, K20, K30… The insert grade is different from companies to companies.
