Introducing the Widin Carbide Corner Radius End Mill — a precision micro-cutting tool built for engineers and machinists who demand clean edges, reliable performance, and deep reach in hard materials. With a 1 mm diameter, 20 mm length, and a subtle R0.2 corner radius, this end mill tackles tight pockets and intricate features with consistent accuracy.

• Diameter: 1 mm for precise, detail-focused milling in small features.
• Overall length: 20 mm reach enables access to tight pockets and deep slots.
• Corner radius: R0.2 for smooth edges, reduced edge wear, and improved edge life.
• Flutes: 2-flute design balances rigidity with efficient chip evacuation.
• Helix angle: 30° to promote effective chip removal and stable cutting action.
• Center cutting: Yes — capable of plunging operations and versatile milling directions.
• Material: Ultra-fine grain carbide delivers solid stiffness and wear resistance.
• Back draft / Long neck geometry: Long neck with back draft aids stability, minimizes vibration, and reduces chatter during cuts on deep grooves and sloped surfaces.
• Hard-material capability: Designed to machine high-hardened materials up to HRc70, expanding its use in challenging applications.
• Neck versatility: Neck length can be effectively leveraged with varying rake angles for flexible machining operations.

This end mill is engineered for practical, real-world use: it supports high-precision finishing on delicate micro-features, maintains consistent surface quality in deep pockets, and resists wear when cutting hardened substrates. Its center-cut capability makes it a versatile choice for profiling, slotting, and pocketing in small-scale assemblies, mold components, and precision tooling. The combination of a tight corner radius, robust carbide composition, and stability-focused geometry helps you achieve reliable results with fewer passes, tighter tolerances, and smoother finishes.
