Manufacturing process

 DURO Coating

is a silicon carbide-based coating with high heat resistance and an ultra-fine nano-level surface structure.
1. This coating is extremely durable, offering excellent heat and wear resistance.
2. It has a long service life and can be used on very hard materials without chipping.  

 EgiAs Coating

Distinctive durability that overwhelms other competitors     
Superior protection against friction with OSG's EgiAs coating 

WXL Coating

is an innovative and improved coating that performs effectively with a wide variety of materials, including nonferrous materials, mild steel, and steels with a hardness of up to 50 HRC. WXL maintains its performance without change in both wet and dry cutting conditions. WXL is designed for diverse applications, from low heat generation and reduced cutting force at high speeds to cutting workpieces requiring high cutting force. Therefore, WXL provides stable performance when used with ball mills, which are susceptible to variations in cutting speed.
