Widin Carbide End Mill - 4 Flute Square Edge Long Neck 2.5mm x 20mm

The Widin Carbide End Mill is a high-precision cutting tool designed to machine hard materials up to HRc70. This 4-flute, square-edge end mill delivers reliable, repeatable cuts for engineers, machinists, and hobbyists tackling demanding projects. It features a 2.5 mm diameter and 20 mm overall length, with a long neck that reaches into draft-angle workpieces without interference.

Built with a newly developed raw material and advanced coating, it supports dry cutting and high-speed cutting for cooler, more efficient performance. These enhancements improve heat resistance, wear resistance, and overall tool life. The ZSLNS20 formulation is engineered to deliver excellent workpiece finishes, producing high-quality surfaces on every pass.

• Long-neck geometry for draft-angle access: The extended neck provides reach into draft-angle features and reduces interference, enabling consistent, stable cuts even in tight or stepped geometries.
• Coated carbide for dry and high-speed cutting: Advanced coating and material deliver improved heat and wear resistance, helping maintain sharpness at higher speeds and extending tool life.
• 4-flute square-edge design for finish-ready cuts: Four flutes balance aggressive material removal with rigidity, promoting efficient chip evacuation and a smooth surface finish.

This end mill is a reliable choice for challenging materials and precision finishes. By enabling deeper access, maintaining performance under heat and wear, and delivering consistent finishes, it helps you streamline setups, reduce tool changes, and achieve superior results across a wide range of machining tasks.
