Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 1.5mm x 4mm

The Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool engineered for precision mold and die machining. Designed for professionals in machine shops, engineering labs, and serious hobbyists, it delivers stable, accurate milling with a focus on durability and reliability.

With a cutting diameter range of 1.0 mm to 20.0 mm and a tight +0/-0.03 mm tolerance, this 4-flute end mill offers versatility across a wide range of workpieces. Its variable-index flutes, combined with 29° and 31° helix angles, reduce chatter and resonance to boost cutting stability and extend tool life. A gash tooth shape helps prevent flute chipping, while the W coating enhances longevity and performance on demanding materials, including those below 55 HRc, pre-hardened steel, alloy steel, and carbon steel.

• Broad cutting diameter range with tight tolerance: Covers 1.0–20.0 mm with a precise +0/-0.03 mm tolerance, enabling consistent part sizes across molds and dies and reducing rework.
• Variable-index 4-flute design for stability: The alternating flute spacing and dual helix angles minimize chatter and harmonics, delivering smoother cuts and longer tool life in tough steels.
• Gash tooth plus W coating for durability: Gash tooth geometry guards against flute chipping, while the W coating improves wear resistance and tool longevity on pre-hardened and carbon steels.

This end mill helps you achieve tighter tolerances with fewer passes, reduces downtime due to wear or chipping, and delivers consistent finishes even in demanding mold and die applications. With its robust carbide composition, specialized geometry, and protective coating, it’s a reliable choice for production runs and precision prototyping alike.
