Widin Carbide Corner Radius End Mill For Mold & Die - 2 Flute Long Neck - 0.8mm x4mm x R0.05

The Widin Carbide Corner Radius End Mill is a precision tool designed for mold and die work. It pairs a tiny 0.8 mm diameter with a 4 mm length of cut, a 0.05 mm corner radius, and a 2-flute design to deliver clean, accurate corners in tight cavities and intricate features.

• Diameter: 0.8 mm
• Length of Cut: 4 mm
• Corner Radius: R0.05
• Flutes: 2-flute design for rigidity and smooth cutting
• Helix Angle: 30° for efficient chip evacuation and lower cutting forces
• Shank/Reach: Long neck for deep groove and cavity access
• Material: Solid carbide for wear resistance and precision
• Applications: Mold and die machining, precision pockets, and detailed features

In practice, this end mill enables crisp, consistent corner radii in complex mold cavities, helping reproduce intricate profiles with minimal finishing. The 30° helix reduces cutting load and improves surface quality, while the long neck provides the reach needed to access deep channels without sacrificing rigidity. Made from carbide, it resists wear and maintains accuracy across multiple jobs, making it a reliable choice for high-precision mold and die workflows. Ideal for micro-milling, fine-detail pocketing, and tasks where precise corners and smooth surfaces matter.
