Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 3mm x8mm x R0.3

Meet the Widin Carbide Corner Radius End Mill—a precision cutting tool designed for machinists and engineers who demand dependable performance on hard materials. With a 3 mm diameter, 8 mm reach, and a 0.3 mm corner radius, this 2-flute, center-cutting end mill delivers smooth edges and stable cuts in demanding applications.

• Diameter: 3 mm
• Length / Reach: 8 mm cutting reach for deep or tight pockets
• Corner radius: R0.3 mm for smooth profiles and reduced edge wear
• Flutes: 2-flute design for efficient chip evacuation
• Material: Ultra-fine grain carbide for high strength and wear resistance
• Helix angle: 30° for effective chip removal and stable cutting
• Center cutting: Yes, enabling plunge milling and versatile operations
• Neck geometry: Long neck with back-draft design to minimize vibration and chatter
• Hardness compatibility: Suitable for machining materials up to HRc70

The combination of a long neck, back-draft geometry, and a precision corner radius makes this end mill ideal for deep grooves, fillets, and sloped surfaces where edge quality matters. The 2-flute configuration and 30° helix promote clean exits and steady chip flow, helping maintain tolerances and surface finish even in challenging materials. Center cutting adds plunge capability, expanding the tool’s versatility across pocketing, ramping, and finishing tasks. This end mill is a reliable choice for toolmakers, mold designers, and production shops tackling high-hardness steels and other demanding alloys.
