Carbide Ball Nose End Mill Cutter — precision milling for demanding jobs Key benefits Durable, performance cutting: made from super finegrain carbide for hardness, wear resistance, and strong heat resistance. Extends tool life and maintains cutting accuracy under heavy use. Versatile and reliable: designed for a wide range of ferrous and alloy materials, reducing tool changes and downtime. Precise contouring and hole/slot work: ball nose geometry delivers smooth surface finishes on 3D contours and accurate slot and hole profiles. What it is Product type: End mills (carbide ball nose end mill cutter) Shank diameter: available from 4 mm to 20 mm Overall length: 100 mm Material: super finegrain carbide with proven milling and cutting performance What it does and why you need it Cuts and mills carbon steel, malleable cast iron, alloy steel, stainless steel, die steel, tool steel, heattreated steel, and similar materials without rapid wear. Ideal for slot and hole machining where consistent geometry and surface finish matter. Handles elevated temperatures and heavy cutting conditions thanks to carbide's heat resistance, helping maintain tolerance and surface quality. Typical applications (practical scenarios) Mold and die finishing: 3D contouring and surface finishing on die steel and heattreated tool steel to achieve smooth radii and precise contours. Component machining in stainless and alloy steels: slotting and hole machining in shafts, housings, and brackets where wear resistance and dimensional accuracy are critical. Production of mechanical parts from carbon and alloy steels: roughing and finishing operations that require long tool life and stable cutting performance. Specifications summary Tool type: Carbide ball nose end mill cutter Shank diameter: 4 mm–20 mm Overall length: 100 mm Material properties: Super finegrain carbide — hardness, wear resistance, heat resistance Recommended for: Slot and hole machining; milling and cutting of listed steels and cast iron Choose this carbide ball nose end mill when you need consistent surface finish, long tool life, and reliable performance across a wide range of steel and castiron materials.
