Widin Carbide Square End Mill For Mold & Die - 4 Flute High Helix (45°) - 8mm x30mm

Widin Carbide Square End Mill for Mold & Die is a precision cutting tool built for mold and die applications. This 4-flute, high-helix end mill uses a robust carbide body with a protective W coating to deliver reliable, clean cuts in demanding steels.

With an 8 mm diameter and 30 mm length, it supports a cutting diameter range from 1.0 mm to 20.0 mm and a tight tolerance of +0/-0.03 mm, ensuring consistent results. The 45° high-helix design reduces cutting load and promotes efficient chip evacuation, helping extend tool life and maintain stable performance when machining below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

• Tight diameter tolerance: Maintains consistent hole, slot, and pocket dimensions with +0/-0.03 mm precision for repeatable results across parts.
• 45° high-helix with efficient chip evacuation: The 45-degree angle reduces cutting forces and improves chip flow, helping heat dissipation and cut stability during mold and die work.
• W-coated carbide for longer tool life: Durable carbide with a protective W coating delivers enhanced wear resistance and machining stability for demanding steels.

This end mill helps you achieve precise, repeatable results in mold and die projects, reducing rework and improving surface quality. The combination of tight size control, efficient chip handling, and wear-resistant coating translates to longer tool life and steadier performance when working with pre-hardened steels, alloy steels, and carbon steels under 55 HRc, making it a dependable choice for professional shops and serious hobbyists alike.
