Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 12mm x 40mm

Widin Carbide Square End Mill for Mold & Die is a high‑performance cutting tool designed for demanding mold and die machining. This 12 mm diameter, 40 mm length end mill is engineered to work across a broad diameter range (1.0 mm to 20.0 mm) with a tight cutting-diameter tolerance of +0/-0.03 mm, delivering precise, repeatable results on challenging pockets and contours.

Its four-flute, variable-index design uses two helix angles (29° and 31°) to reduce chatter, lower resonance, and extend tool life, while a purpose-built gash tooth shape helps prevent flute chipping. Built from premium carbide and finished with a W coating, it combines wear resistance with dependable performance on materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

• Variable-index 4-flute design for stability: Reduces chatter and resonance during mold and die machining, enabling smoother cuts and more predictable tool life.
• Gash tooth geometry to prevent flute chipping: Specially shaped teeth guard against micro‑chipping in tough materials, ensuring durability and reliable performance across heavy cuts.
• W coating for extended wear life: Hardened surface reduces wear, improves heat resistance, and helps maintain precision over longer run times.

With these features, the end mill delivers consistent performance on challenging steels and alloys, minimizes downtime from wear or chip-out, and supports efficient workflows. The carbide construction and W coating ensure reliable cutting in pre-hardened steel, alloy steel, and carbon steel, while the 12 mm x 40 mm size provides the rigidity and reach needed for pockets, contours, and complex mold geometries—helping you finish parts faster with repeatable accuracy.
