The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for engineers and machinists who demand durable, accurate performance in challenging materials. With a 1.5 mm diameter, 4 mm cutting length, and an R0.1 corner radius, this 2-flute tool delivers clean edges and reliable results in tight spaces.

• Diameter: 1.5 mm
• Cutting length: 4 mm
• Corner radius: R0.1
• Flutes: 2
• Material: Ultra-fine grain carbide
• Helix angle: 30°
• Center cutting: Yes
• Neck design: Long neck with back draft for enhanced stability
• Chip evacuation: Efficient chip removal supports smooth cutting and reduces clogging
• Material capability: Suitable for high-hardened materials up to HRc70
• Neck length adjustment: Rake-angle dependent neck length for flexible reach

The end mill is engineered to tackle demanding tasks with confidence. The corner radius smooths edges and reduces wear on fragile features, while the long neck and back-draft geometry diminish vibration and chatter during deep-grooving, pocketing, or cutting on sloped surfaces. Center cutting enables plunging and ramping operations, expanding its versatility in intricate milling layouts. Built from ultra-fine grain carbide, it delivers outstanding rigidity and wear resistance for extended tool life, even when machining hard materials up to HRc70. The rake-angle–based neck length adjustment provides additional flexibility, letting you tailor reach to match specific geometries without sacrificing precision.
