Description
Widin Carbide Square End Mill for Mold & Die — 4 Flute Long Neck, 5mm x 20mm is a reliable tool built for precision mold and die machining. It supports a cutting diameter range from 1.0 mm to 12.0 mm with a tight tolerance of +0/-0.03 mm, helping you achieve consistent, accurate results across jobs. The long neck geometry provides a smooth transition from the shank to the cutting edge, reducing stress during demanding cuts and improving durability.
Crafted from premium carbide and enhanced with a durable W coating, this end mill delivers superior wear resistance, stability, and long tool life. The combination of robust materials and coating supports reliable performance in mold and die work below 55 HRc, as well as machining pre-hardened steel, alloy steel, and carbon steel.
- Long-neck geometry for enhanced durability: The extended transition between the shank and neck reduces stress concentrations, helping prevent breakage during deep cuts and heavy milling.
- Tight cutting-diameter tolerance: Diameter control of +0/-0.03 mm ensures consistent sizing and repeatable results across parts and setups.
- W-coated carbide for wear resistance: The durable coating plus carbide substrate deliver extended tool life, steadier cutting action, and fewer wear-driven interruptions.
This end mill is designed to improve efficiency and reliability in mold and die applications, delivering cleaner finishes, reduced downtime, and dependable performance across a range of common steels. Use it to achieve consistent results, longer tool life, and steady machining stability in demanding projects.
