The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed for mold makers, die shops, engineers, and hobbyists who need accurate corners and smooth finishes. This 4 mm diameter, 70 mm length end mill features a 0.3 mm corner radius and a 2-flute configuration to deliver stable cuts with reduced chatter. It is available in multiple specifications to fit a range of deep groove and contouring tasks.

With a tapered neck, this end mill increases rigidity along the cutting edge, delivering steady, precise performance in deep groove machining and challenging cavities. The combination of carbide hardiness and optimized geometry helps maintain accuracy across use, while the broad specification options let you select the right tool for your exact mold & die application.

• Tapered Neck for Enhanced Rigidity: The tapered effective length boosts stability along the cut, reducing deflection and enabling precise, repeatable results in deep groove and contour work.
• 2-Flute Carbide Design for Efficient Cutting: Lightweight flute geometry lowers cutting forces and minimizes vibration, improving surface finish and reducing tool wear during mold and die operations.
• Corner Radius for Defined, Durable Edges: The built-in corner radius preserves corner geometry for cleaner pockets and corners, enhancing finish quality and edge durability in demanding applications.

Whether you're shaping cavities, finishing contours, or milling deep grooves in mold and die components, this end mill helps you work faster with fewer passes and more consistent results. The carbide construction delivers reliable performance, while the 0.3 mm corner radius and 4 mm diameter are tuned for precise, repeatable cuts across a range of materials.
