Tungsten Carbide Rods (with Coolant Holes)
These are tungsten carbide rods with internal coolant holes, manufactured by Zhuzhou Ruiao Tungsten Carbide Co., Ltd., serving as core raw materials in the machining industry.
✨ Key Features
Material Properties
Made primarily of tungsten carbide (WC) via powder metallurgy, they feature high hardness, excellent wear resistance, and high rigidity, capable of withstanding the harsh conditions of high-speed cutting.
2.Coolant Hole Design
The rods are equipped with single or double straight holes, which act as internal coolant channels. These holes deliver cutting fluid directly to the cutting zone, effectively reducing heat and aiding chip removal, thus significantly extending tool life and improving machining stability.
3.Diverse Specifications
The image displays rods of varying diameters, ranging from large-diameter double-hole rods to small-diameter single-hole rods, suitable for manufacturing tools of different sizes.
🛠️ Main Applications
Solid Carbide Tool Manufacturing: They are the primary blanks for making internal-coolant drills, end mills, reamers, and other solid carbide tools, especially for deep-hole drilling and high-speed milling operations requiring high-pressure cooling.
-
Wear-Resistant Components: They can also be processed into punches, core rods, piercing tools, and other wear-resistant parts for use in molds, petroleum, and geological drilling industries.
💡 Additional Notes
These rods require extremely high precision in hole position, straightness, and surface finish, usually achieved through precision grinding to ensure coaxiality and optimal cooling performance in subsequent tool manufacturing. Zhuzhou, a major hub of China's tungsten carbide industry, is a key production base for such products.
