Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 2mm x 4mm

The Widin Carbide Square End Mill is a high-performance cutting tool designed for mold and die machining. Built for engineers, machinists, and hobbyists alike, it delivers precise, reliable milling across a wide range of features and materials. Its square end geometry enables crisp corners and accurate slots for molds and die components, making it a versatile choice on demanding shops.

Equipped with a broad cutting diameter range of 1.0 mm to 20.0 mm and a tight size tolerance of +0/-0.03 mm, this end mill adapts to many job sizes without sacrificing accuracy. The four-flute, variable-index design, combined with two helix angles (29° and 31°), reduces chatter and resonance to deliver stable cuts, longer tool life, and smoother finishes. A purpose-built gash tooth shape helps prevent flute chipping, and the W coating further boosts wear resistance and longevity when machining steel alloys, including pre-hardened stock up to 55 HRC.

• Variable-index 4-flute design: Reduces chatter and vibration, improving stability and extending tool life for clean, consistent cuts across complex mold features.
• Wide diameter range with tight tolerance: Covers 1.0–20.0 mm with +0/-0.03 mm accuracy, enabling you to complete multiple mold/die tasks without swapping tools.
• Gash tooth geometry with W coating: Prevents flute chipping and delivers enhanced wear resistance, helping you cut pre-hardened and alloy steels more reliably and with longer tool life.

This end mill helps you speed up mold and die work, achieve precise features, and maintain consistent results with fewer tool changes. The durable carbide construction, protective W coating, and chip-resistant geometry translate to longer intervals between replacements and lower downtime, so you can finish projects faster and with high-quality finishes.
