Widin Carbide Corner Radius End Mill - 2 Flute Long Neck Back Draft Type - 2mm x20mm x R0.8

Introducing the Widin Carbide Corner Radius End Mill — a 2-flute, long-neck back-draft end mill engineered for precision milling on hard materials. Designed for machinists and engineers who demand reliable radii, stable cuts, and versatile reach in tight pockets and deep grooves.

• Diameter: Ø2 mm
• Neck Length: 20 mm long neck for reach in deep pockets
• Corner Radius: R0.8 mm for smooth edges and reduced wear
• Flutes: 2-flute design for efficient cutting and chip control
• Helix Angle: 30° for effective chip evacuation and surface finish
• Center Cutting: Yes, enabling plunging and pocket milling
• Material: Ultra-fine grain carbide for strength and longevity
• Geometry: Long-neck with back-draft design to improve stability and reduce chatter
• Material Compatibility: Suitable for high-hardened materials up to HRc70

Whether you're finishing radii on hardened steel, slotting, or deburring edges, this end mill delivers precise, repeatable results. The corner radius minimizes edge chipping and promotes longer tool life, while the long neck provides access to deep features without compromising rigidity. The 30° helix, combined with back-draft geometry, reduces vibration and chatter, yielding smoother cuts on sloped surfaces and during high-feed operations. Center cutting capability expands your options to plunge milled features and sharp corners, making it versatile for mold making, automotive components, and complex pockets. Crafted from ultra-fine grain carbide and capable of machining materials up to HRc70, it’s a reliable workhorse for challenging tasks where precise radii and clean finishes matter.
