Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 2.5mm x 2.5mm

The Widin Carbide Square End Mill for Mold & Die is a high-performance cutting tool built for the rigors of mold and die machining. With a versatile cutting diameter range from 1.0 mm to 20.0 mm and a tight tolerance of +0 / -0.03 mm, it delivers precise pockets, slots, and profiles across a wide range of workpieces.

Designed for professionals who demand reliability, this 4-flute end mill uses a variable-index geometry with two helix angles (29° and 31°) to reduce chatter, improve cutting stability, and extend tool life. The gash tooth shape helps prevent flute chipping, while the W coating enhances wear resistance for longer performance. Made from premium carbide and engineered for materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

• Variable-Index 4-Flute Geometry: Reduces chatter and vibration while lengthening tool life, providing smooth, stable cuts across a range of mold and die profiles.
• Dual Helix Angles (29° & 31°): Optimizes chip evacuation and cutting load distribution for cleaner slots and pockets with less vibration.
• Gash Tooth Design with W Coating: Prevents flute chipping and delivers outstanding wear resistance, enabling longer tool life on tough materials.

This end mill is designed to improve your workflow by delivering accurate, clean cuts and longer tool life, even in demanding materials. Users will notice steadier feeds, fewer tool changes, and consistent finishes on mold cavities, cores, and die features, helping you finish projects faster with reliable results.
