• Material: Ultra-fine grain carbide for exceptional strength and wear resistance
• Corner radius: R0.05 for smooth edges and reduced wear on delicate features
• Helix angle: 30° for efficient chip evacuation and smooth cutting
• Neck design: Long neck with back draft geometry to improve rigidity and reduce vibration
• Center cutting: Yes, enabling versatile plunging and pocketing operations
• Back draft type: Designed to minimize chatter during deep cuts and on sloped surfaces
• Material compatibility: Suitable for high-hardened materials up to HRc70
• Application versatility: Ideal for deep grooves, precise pockets, and intricate features with tight tolerances

The Widin end mill combines a tiny diameter with a robust carbide core, enabling precise, repeatable cuts in hard materials. The corner radius maintains edge integrity on small features, while the long neck provides clearance for deep cavities and complex geometries. Center cutting and the 30° helix work together to deliver clean finishes and reliable tool life, even when machining challenging materials. Use this tool for high-precision work where smooth edges and accurate depths matter, and pair it with proper feeds, speeds, and pecking strategies to maximize performance.
