Widin Carbide Square End Mill For Mold & Die - 4 Flute High Helix (45°) - 16mm x40mm

Introducing the Widin Carbide Square End Mill for Mold & Die — a precise, reliable tool designed for mold and die machining. This 4-flute, high-helix end mill (45°) is sized 16 mm in diameter with a 40 mm length and covers cutting diameters from 1.0 to 20.0 mm for versatile tasks.

It features a tight tolerance of +0/−0.03 mm and a W-coated carbide body for longevity. The 45° high-helix design reduces cutting load and promotes efficient chip evacuation, making it suitable for mold and die work on steel up to 55 HRc, including pre-hardened, alloy, and carbon steels.

• Wide cutting diameter range (1.0–20.0 mm): Achieve profiling, pocketing, and finishing with a single tool, reducing tool changes and simplifying setups while maintaining tight tolerances.
• 45° high-helix design for smoother cutting and chip evacuation: The steeper angle lowers cutting forces and clears chips quickly, improving surface finish and extending tool life in challenging materials.
• W-coated carbide for durability: The durable carbide substrate paired with a wear-resistant coating delivers longer tool life, stable performance, and fewer replacements on demanding mold-and-die tasks.

With precise size control and durable construction, this end mill helps you complete molds and dies faster, reduce downtime, and achieve consistent, high-quality surfaces across materials like pre-hardened steel and carbon steel. By delivering reliable performance pass after pass, it supports tighter tolerances and repeatable results, making it a dependable choice for engineers, machinists, and hobbyists alike.
