Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 5mm x 20mm

Widin Carbide Square End Mill for Mold & Die is a high-performance milling tool designed to deliver precision in mold and die work. With a cutting diameter range from 1.0 mm to 20.0 mm and a tight tolerance of +0/-0.03 mm, it handles a wide variety of cavity sizes and features with reliable accuracy.

Its 4-flute, variable-index design with dual-helix angles (29° and 31°) reduces chatter and improves cutting stability at higher feeds, while the gash tooth geometry helps prevent flute chipping for durable, long-lasting performance. Coated with W for extended life, this end mill is built to cut materials below 55 HRc as well as pre-hardened steel, alloy steel, and carbon steel, making it a versatile choice for demanding mold and die applications.

• Variable-index 4-flute design with dual-helix angles: Smooths cutting action and reduces chatter, boosting stability and tool life across varying feeds and materials.
• Wide diameter range with tight tolerance: 1.0–20.0 mm with +0/−0.03 mm precision enables consistent pocketing and profiling, minimizing rework and tool changes.
• Gash tooth geometry with W coating: Helps prevent flute chipping while delivering enhanced wear resistance and longer service life on steels and alloys.

Designed for durability and precision in demanding mold and die work, this end mill delivers predictable results across a range of steels and alloys. The dual-helix, variable-index geometry minimizes vibration, enabling higher feeds and cleaner finishes with fewer passes. The premium carbide substrate combined with the W coating reduces wear, maintaining sharpness longer and cutting downtime. Whether pocketing softer pre-hardened steel or profiling complex cavities, this tool provides reliable, consistent performance from first cut to last.
