Main Features
1. Using ultra-thick grain cemented carbide raw materials, the alloy is subjected to pressure sintering to increase the hardness and toughness of the drill by 30%.
2. Unique design, the drilling speed is increased by 20% and the life is increased by 30%.
3. Use imported high-grade steel to make the pants body, ensure the overall performance of the drill bit is consistent, and the pants body does not break.
4. After-sales protection, return the defective product package.
