从China供应商批量进口2flutes/4flutes Ball Nose End Mills

These are solid carbide 2-flute and 4-flute ball nose end mills offered in a wide array of shank and overall length combinations. The listed variants include shank diameters of 1.5 mm to 20 mm with corresponding flute lengths of 4.5 mm to 60 mm, matching standard tool-holder interfaces for CNC machining centres. Each mill features a spherical cutting tip for 3D contouring and a centre-cutting design that allows plunging into the workpiece.

The cutting edges use micro-grain carbide substrate with typical PVD TiAlN coating for heat resistance and extended tool life at high spindle speeds. Standard tolerances for diameter are h6, while overall length and flute length conform to DIN 6537-1 for ball nose mills. The 2-flute version excels in non-ferrous materials like aluminium and copper, whereas the 4-flute geometry is optimised for steels and harder alloys, balancing chip evacuation with surface finish.

Machinists in aerospace, die and mould, and precision engineering specify these mills for 3-axis and 5-axis roughing and finishing of curved surfaces, pockets, and cavities. Common applications include turbine blade profiling, injection mould cavities, and complex die sinking. Buyers confirm minimum order quantities, coating options, and corner radius tolerances directly with Dongguan Haiying Cutting Tool, as these parameters are set per batch.

Dongguan Haiying Cutting Tool Co., Ltd. is based in Tiankeng Village, Hengli Town, Dongguan City, Guangdong Province, China. The company’s listed address confirms its location within a known manufacturing hub for precision cutting tools, serving domestic and export markets.

The supplier operates under a harbor trust tier with no recorded response rate or average response time in the available data. This means buyers should expect to initiate contact through the provided channels to verify lead times, batch-specific tolerances, and additional coating or geometry options. No further operational details, such as workforce size or certifications, are disclosed in the current profile.
