Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 1mm x 4mm

Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool engineered for precision mold and die machining. It offers a wide cutting diameter range from 1.0 mm to 20.0 mm with a tight diameter tolerance of +0/-0.03 mm, enabling accurate sizing across various workpieces.

The tool employs a variable index 4-flute configuration with dual helix angles of 29° and 31°, designed to reduce chatter and resonance for smoother cuts and improved cutting stability. A gash tooth shape helps prevent flute chipping, delivering dependable performance even under demanding conditions. Crafted from premium carbide and finished with a W coating, it delivers extended wear resistance and longevity for tough materials, including those below 55 HRc and common mold steels such as pre-hardened, alloy, and carbon steels.

• Variable index 4-flute design: Delivers smoother cuts with reduced vibration and stable chip formation, improving finish quality and extending tool life across a wide range of sizes.
• Gash tooth geometry: Specifically engineered to prevent flute chipping, helping maintain sharp edges and reliable performance in challenging cuts.
• W coating on premium carbide: Enhances wear resistance and heat dissipation, enabling longer tool life and consistent performance when machining hard steels and molded parts.

This end mill helps you streamline mold and die workloads by delivering precise, repeatable results across a broad diameter range, reducing tool changes, and improving overall productivity. With its durable construction, reliable cutting stability, and enhanced longevity, it supports accurate feature definition, better surface finishes, and fewer reworks in demanding manufacturing environments.
