Widin Carbide End Mill - 4 Flute Neck Type Square Edge - 3.5mm

The Widin Carbide End Mill is a 3.5 mm diameter, 4-flute neck-type end mill with a square edge. Built to cut high-hardened materials, it delivers reliable performance in demanding milling tasks, from hardened steels to precision molds.

Its innovative construction combines a newly developed substrate and an advanced coating, enabling efficient dry cutting and high-speed operation. This design reduces cutting forces, promotes smooth chip evacuation, and helps you achieve excellent surface quality and tight dimensional accuracy on tough workpieces.

• Hardness-Ready Cutting (up to HRc70): Engineered to machine materials as hard as HRc70, delivering consistent edge life and predictable results in tough, high-strength workpieces.
• Dry and High-Speed Cutting: The advanced coating and geometry minimize cutting forces, support dry cutting without coolant, and boost productivity with cooler, smoother operation.
• Rigid Neck-Type 4-Flute Geometry: Neck design combined with four flutes provides rigidity, controlled chip evacuation, and a high-quality finish across challenging slots and pockets.

This end mill helps you speed up workflows, reduce tool changes, and achieve repeatable, high-precision results even when machining hardened materials. Its combination of durable carbide substrate, modern coating, and optimized geometry delivers reliable performance, smooth finishes, and long tool life—making it a dependable choice for engineers, manufacturers, and hobbyists alike.
