What is Rods with Two Straight Coolant Holes

Rods with Two Straight Coolant Holes are a type of metal rods that are made of tungsten carbide, a hard and durable material that can withstand high temperatures and pressures. Rods with Two Straight Coolant Holes have two holes in the center that are parallel to each other and allow coolant to flow through them, which helps to reduce the heat and friction during the cutting process.



Advantages of Rods with Two Straight Coolant Holes

Rods with Two Straight Coolant Holes have many advantages over other types of rods. They have high hardness, wear resistance, corrosion resistance, and bending strength, which make them suitable for various cutting tools and molds. They also have high thermal conductivity, which improves the efficiency and quality of the machining. Moreover, they have low coefficient of thermal expansion, which prevents them from deforming or cracking under high temperatures.

The production process of Rods with Two Straight Coolant Holes

Rods with Two Straight Coolant Holes are produced by a sophisticated process that involves mixing, pressing, sintering, and grinding. First, the tungsten carbide powder is mixed with a binder, such as cobalt or nickel, to form a homogeneous mixture. Then, the mixture is pressed into a rod shape with two holes in the center. Next, the rod is sintered at a high temperature and pressure to bond the particles together and form a solid material. Finally, the rod is ground to achieve the desired size and surface finish.

Rods with Two Straight Coolant Holes are widely used in various industries and applications. They are mainly used for making drills, end mills, reamers, taps, and other cutting tools that require high precision and performance. They are also used for making dies, punches, rollers, and other molds that require high wear resistance and durability. Rods with Two Straight Coolant Holes can cut various materials, such as steel, iron, aluminum, copper, titanium, and plastic.
