Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 1.2mm x 3mm

Widin Carbide Square End Mill for Mold & Die combines power with precision for demanding mold and die machining. This 4-flute, square-end carbide tool is built to handle a wide range of workpieces, offering versatility from 1.0 mm to 20.0 mm cutting diameters with a tight +0/-0.03 mm tolerance. The listing includes a 1.2 mm x 3 mm size for those applications that require a compact, precise cut.

Designed for reliability in tough machining environments, it uses a variable-index flute arrangement with 29° and 31° helix angles to reduce chatter and resonance, delivering stable cutting and longer tool life. The gash tooth shape is specifically engineered to prevent flute chipping, helping maintain consistent performance during long runs. Crafted from premium carbide and finished with a W coating, this end mill offers superior wear resistance and longevity, suitable for materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

• Variable-index 4-flute design with dual-helix geometry: Smooth, stable cutting with reduced vibration for cleaner finishes and longer tool life.
• Gash tooth geometry to prevent flute chipping: Enhanced durability and reliability during extended milling runs.
• W-coated carbide with broad material compatibility: Increased wear resistance and longevity for tough mold/die steels, minimizing downtime.

This end mill is designed to improve workflow and outcomes across mold and die projects. Expect repeatable tolerances, better surface finishes, and fewer tool changes as you work with a range of steels below 55 HRc. The combination of a robust carbide core, smart flute geometry, and protective coating helps you achieve precise, efficient machining from pocketing to finishing passes.
