Cemented carbide rods with helical holes are widely recognized as high-performance materials in modern cutting tool production. They are the core base for drills, end mills, and other precision tools that require excellent cooling, long tool life, and high machining efficiency. Understanding the manufacturing process of these rods reveals why they are superior to traditional straight hole designs.
1. Powder Metallurgy – The Core of Cemented Carbide Strength
The production of cemented carbide rods with helical holes starts with powder metallurgy. Fine tungsten carbide powders are blended with a cobalt binder, pressed into rod shapes, and sintered at very high temperatures. This process produces a dense, ultra-hard structure that ensures:
-
Exceptional hardness and wear resistance
-
High thermal stability during machining
-
Sufficient toughness to withstand cutting forces
This solid foundation allows cemented carbide rods to serve as reliable raw materials for advanced cutting tools.
2. Precision Formation of Helical Holes
The defining feature of cemented carbide rods with helical holes is the spiral cooling channels inside the rod. These helical holes are formed during extrusion or pressing by specialized molds, ensuring precise geometry and uniform distribution within the rod.
Compared to straight holes, the helical hole design provides:
-
More effective coolant flow along the cutting edge
-
Superior heat dissipation and temperature control
-
Improved chip evacuation for smoother machining
This precision engineering makes the rods ideal for demanding applications such as high-speed drilling and deep-hole machining.
3. Technical Challenges and Advantages Over Straight Hole Rods
Manufacturing cemented carbide rods with helical holes requires advanced technology. Achieving the correct spiral path without compromising the rod’s strength is significantly more complex than producing rods with straight cooling holes.
Despite the higher technical difficulty, the benefits are clear:
-
Enhanced cooling performance for stable cutting
-
Extended tool life due to reduced wear and thermal stress
-
Higher machining efficiency in aerospace, automotive, and precision mold industries
