Description
The Widin Carbide End Mill is a precision cutting tool built for high-hardness materials. This 4‑flute square‑edge end mill comes in a compact 2 mm diameter with an 18 mm length, making it ideal for precise profiling in tight spaces and challenging setups.
Its long-neck design provides the necessary clearance when machining workpieces with draft angles. The tool’s effective neck length is optimized to accommodate longer interference lengths, helping you avoid collisions and maintain consistent cuts across varying draft conditions. Engineered with a newly developed raw material and an advanced coating, it supports dry cutting and high‑speed operation for enhanced heat resistance, wear resistance, and overall performance. The ZSLNS20 design is engineered to deliver excellent workpiece finishes, making it a reliable choice for demanding materials and high‑quality results.
- Long-neck reach for draft-angle work: The extended neck provides clearance and access to angled surfaces and deep pockets, reducing interference and enabling accurate profiling.
- Dry and high-speed cutting with advanced coating: Specially developed materials and coating deliver superior heat and wear resistance, supporting fast feeds and reliable dry cutting.
- 4-flute square-edge design for finishes you can trust: Four cutting edges and a square geometry promote efficient chip evacuation, stable cutting, and smooth finishes on hard materials with durable tool life.
In practice, this end mill translates to consistent, high-quality surface finishes on hardened steels while offering reliable reach and cutting performance. Whether you’re prototyping or running production tasks that involve draft-angle features, the Widin 2 mm, 18 mm end mill helps you complete jobs faster with fewer tool changes and predictable results.
