Widin Carbide Corner Radius End Mill is a precision cutting tool built for micro-machining tasks in hardened materials. Designed for engineers and machinists who demand dependable performance, this 1 mm diameter, 16 mm reach, 2-flute end mill features a corner radius of R0.2 and a long neck with back draft, delivering clean, repeatable results in tight pockets and tricky contours.

• Diameter: 1 mm
• Overall length / reach: 16 mm with a long neck to access deep features
• Flutes: 2 flutes for efficient chip evacuation and stable cutting
• Material: Ultra-fine grain carbide for high strength and wear resistance
• Corner radius: R0.2 for smooth edges and reduced edge wear
• Center cutting: Capable of plunging and pocketing in a variety of workpieces
• Helix angle: 30° for effective chip evacuation and clean cuts
• Back draft / neck design: Long neck with back draft geometry to minimize vibration and chatter
• Hardness compatibility: Suitable for machining materials up to HRc70, handling tough applications

In practice, this end mill enables precise, burr-free finishes in deep grooves and at inclined surfaces, while maintaining stability through challenging cuts. The corner radius reduces edge wear and helps preserve part geometry, and the long neck with back draft design increases rigidity during deep-pocket operations. With its balanced geometry and hardened-material capability, it’s well-suited for mold making, aerospace components, tooling, and other high-precision applications where repeatable accuracy matters.
