Widin Carbide Square End Mill For Mold & Die - 4 Flute Long Neck - 3mm x 50mm

Widin Carbide Square End Mill for Mold & Die, 4 Flute Long Neck, 3 mm x 50 mm, is a precision cutting tool engineered for demanding mold and die work. With a 3.0 mm cutting diameter and a tight +0/−0.03 mm tolerance, it delivers dependable, repeatable dimensions across profiles. The long neck design provides extended reach for deep pockets and complex geometries, making it a reliable choice for high-precision machining where consistency matters.

This end mill combines premium carbide with a durable W coating to maximize wear resistance and tool life, even in challenging materials. The extended neck transition between shank and cutting portion helps absorb side loads and reduces the risk of breakage during aggressive milling. Crafted for durability, it excels in mold and die applications below 55 HRc, and is well-suited for pre-hardened steel, alloy steel, and carbon steel.

• Long-neck geometry for added durability: The extended shank-to-neck transition provides greater reach while maintaining core strength, reducing breakage during deep pockets and heavy cuts.
• W-coated carbide for wear resistance: The durable coating works with hard steels to extend tool life and maintain stable performance through demanding finishing passes.
• Precise diameter with versatile material compatibility: 3.0 mm cutting diameter and +0/−0.03 mm tolerance ensure consistent results, suitable for mold & die work on steels under 55 HRc, including pre-hardened, alloy, and carbon steels.

This end mill helps you maintain tight tolerances and achieve cleaner finishes with fewer tool changes. Its combination of hard carbide, wear-resistant coating, and thoughtful geometry supports reliable, repeatable results across a range of mold and die applications, improving workflow efficiency and overall machining performance.
