Import 4 Flutes Carbide End Mill With Tiny Diameter Mad — Buy in Bulk from Supplier in China

This 4 flute carbide end mill is engineered for precision machining in applications requiring tiny diameter tools, such as micro-milling or intricate detail work in steel and cast iron. The flute length of 4 mm is designed for shallow cuts, making it ideal for high-speed operations where fine surface finishes are critical. The carbide material ensures exceptional hardness and wear resistance, even at elevated temperatures.

The 4 flute configuration enhances chip removal, reducing the risk of clogging and heat buildup in tight spaces. Tiny diameter end mills typically range from 0.5 mm to 3 mm in cutting diameter, with shank diameters often matching or slightly exceeding the cutting edge for stability. Standard coatings for such tools include TiAlN or AlTiN for improved thermal resistance, while the flute geometry is optimized for rigidity to minimize deflection during operation.

These end mills are widely used in aerospace, medical device manufacturing, and electronics industries, where precision and repeatability are paramount. They are packaged to prevent edge damage during transit, with options for bulk shipments under FOB or CIF terms. Buyers should confirm the exact diameter tolerance and runout specifications, as these directly impact the tool’s performance in micro-machining applications.

Xi’an Winway Tools Co., Ltd. is based in the Oak Block International Building, No.36 Xi’an, Shaanxi Province, China. The company focuses on precision tooling, including carbide end mills designed for high-speed and micro-machining applications. Its imported tier classification indicates it distributes tools from manufacturers, serving industries where fine tolerances and durability are essential.

The supplier holds a harbor trust tier, which provides a baseline level of verification for international trade. However, its response rate and average response hours are currently unavailable, so buyers are advised to contact the supplier directly for technical details and availability. Xi’an Winway Tools emphasizes standardized packaging and global distribution, catering to buyers in aerospace, medical, and electronics sectors.
