uxcell 2pcs Ball Nose End Mills CNC Router Bits, 0.5mm (5 /256 inch) Radius Solid Carbide TiSin Coated 2 Flutes HRC55 1mm (5 /128 inch) Diameter 4mm (5 /32 inch) Shank Cutter Milling Tools

Features

• Ball Nose End Mill Size: Cutting radius: 0.5mm / 5/256"; cutting diameter: 1mm / 5/128"; cutting length: 2mm / 5/64"; shank diameter: 4mm / 5/32"; total length: 50mm / 2"; cutting hardness: HRC55; number of flutes: 2 flutes; end cut type: ball end
• Wide Applications: Double-edged ball nose design, suitable for semi-finishing and finishing of various curved surfaces and arc grooves; Small ball end mills can perform small chamfer milling on steep/straight walls and contoured surfaces. Suitable for materials below HRC55, such as carbon steel, cast iron, alloy steel, stainless steel, non-ferrous metals, etc.
• TiSin Composite Coating: TiSin (titanium silicon nitride) composite coating further enhances wear resistance and heat resistance, reduces friction and cutting forces, improves chip evacuation, and extends tool life. This improves processing efficiency and surface finish for clean, accurate cuts.
• Solid Carbide: Solid carbide end mills offer high hardness, wear resistance, and heat resistance. CNC router bits are precision ground and polished, with high strength and good milling performance. The cutting edges are finely ground for smooth cuts. Large Spiral chip space design for fast and clean chip removal.
• Easy to Use: Universal chamfered round shank, good compatibility and easy to use. Use on standard milling machines, CNC machining centers, engraving machines. The longer the length of the tool clamped by the chuck, the better. Use a suitable coolant or lubrication method during milling operations
