Widin Carbide Corner Radius End Mill For Mold & Die - Variable Index 4 Flute - 4mmx 30mm X R0.3 FMH FLH FHH S&E A&NF M&D Helix Angle: 45° to reduce

Helix Angle: 45° to reduce cutting forces and promote excellent chip evacuation

Material: HSS-E (high-speed steel with cobalt) for added durability

4‑flute variable‑index design with W coating: Helix angles of 29° (first flute) and 31° (second flute) minimize chatter and vibration

Flute Geometry: 2-flute ball nose for efficient cutting and excellent surface finishes

45° Helix Optimized for Aluminum & Non‑Ferrous: Guides chips away quickly

Widin Carbide Corner Radius End Mill For Mold & Die - Variable Index 4 Flute - 4mmx 30mm X R0.3 FMH FLH FHH S&E A&NF M&D Helix Angle: 45° to reduceThe Widin Carbide Corner Radius End Mill is a high performance cutting tool built for mold and die machining. With a 4 mm diameter, 30 mm overall length, and a corner radius of R0. 3, it handles precise, repeatable profiles with ease. Its variable index geometry optimizes edge distribution, reducing cutting forces and promoting efficient chip evacuation for smoother finishes and more consistent results through every pass. Designed with deep cavities
