Description
Widin's carbide square end mill is designed for mold and die work, delivering precise square-edged cuts with a 4 mm shank in a robust carbide body. The W coating provides enhanced wear resistance and machining stability, helping you achieve repeatable, clean pockets and corners in demanding materials.
Built with a gash tooth geometry to reduce flute chipping and a tight diameter tolerance of +0/-0.012 mm, this end mill stays consistent across passes. It covers a cutting diameter range from 0.1 mm to 20.0 mm with 0.1 mm increments, and is ideal for mold & die machining in materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.
- W coating for longer tool life: The protective W coating improves wear resistance and machining stability, helping the cutter maintain sharpness through demanding cuts and extend service life.
- Gash tooth design reduces flute chipping: The specialized geometry minimizes edge damage during heavy cuts, promoting consistent performance and cleaner corners.
- 0.1 mm increments with a 4 mm shank: Provides precise diameter selection and a sturdy, compatible shank for reliable clamping and stable milling in mold and die applications.
Together, this Widin end mill delivers reliable, repeatable results in mold and die tasks. Expect tight tolerances, smooth surface finishes, and reduced downtime thanks to longer tool life and stable performance across common steels such as pre-hardened, alloy, and carbon steel (materials below 55 HRc).
