How to choose the right insert color

Among all kinds of tools used in daily life, from industrial production to daily life, insert of different colors are not only a visual distinction, but are also closely related to performance and purpose.

Silver insert

Silver inserts are usually made of high-speed steel or ordinary carbon steel. When not treated with special coatings, they show the original silver-gray color of the metal. High-speed steel silver inserts are widely used in the field of mechanical processing due to their excellent wear resistance and high cutting speed. For example, in the turning and milling process of metal parts, high-speed steel silver inserts can cut continuously and stably to ensure processing accuracy while extending the service life of the tool. Ordinary carbon steel silver inserts are relatively low in cost. Although their cutting performance is slightly inferior, they can meet the needs of some wood processing scenarios where precision requirements are not high.

Black insert

Many inserts are black, thanks to the titanium nitride (TiN) coating. The titanium nitride coating not only gives the insert a unique appearance, but also significantly improves performance. During the tool cutting process, the titanium nitride coating can reduce friction and reduce heat generation, which is particularly effective for processing some materials that are prone to high temperatures, such as stainless steel and aluminum alloys. Taking aluminum alloy processing as an example, black inserts can effectively prevent aluminum alloys from deforming due to high temperatures during processing due to their excellent heat dissipation and low friction characteristics, thereby ensuring processing quality. In addition, black inserts are more resistant to corrosion. In a humid working environment or one containing corrosive substances, their service life is greatly extended compared to silver inserts, further reducing maintenance costs and the frequency of tool replacement.

Golden Blade

The surface of the gold insert is coated with titanium aluminum nitride (TiAlN), which makes the insert have excellent high temperature resistance and can still maintain good cutting performance in high temperature environment. In the field of aerospace, difficult-to-process materials such as titanium alloys and nickel-based alloys are widely used. These materials are not only hard, but also generate a lot of heat during the processing, which places extremely high demands on the performance of the tool. With its excellent high temperature resistance, the gold insert can easily cope with these challenges and ensure processing accuracy and efficiency.
