The use of imported high-precision automatic presses for production,minimizing human factors and eliminating macro- level
contamination and void defects,ensuring excellent and stable product quality.
Sintering is carried out using a German-made,original imported pressure sintering furnace,resulting in zero porosity inside the alloy.Theimpact toughness is over 20% higher than that of conventional vacuum sintered products,ensuring superior performance of the cemented carbide.

Usage Recommendations:The cemented carbide for the cutting edge would be better to use our TK13C grade cemented carbide inserts. This grade ensures excellent wear resistance while providing outstanding impact toughness, greatly reducing the likelihood of carbide cracking under impact. Additionally, its excellent weldability minimizes the risk of alloy cracking due to welding stress. For the back part, it is recommended to use TK11C grade cemented carbide bars, as the back experiences less impact and this grade offers higher wear resistance. This combination maximizes the balance between tool wear and abnormal
damage, ensuring long-distance drilling performance.
