Widin Carbide Square End Mill For Mold & Die - Variable Index 4 Flute For Powerful Cutting - 3mm x 3mm

Widin Carbide Square End Mill for Mold & Die is a precision milling tool designed to tackle intricate cavities, pockets, and profiles in mold and die work. With a square end and four flutes, it delivers clean corners and efficient material removal, making it a dependable choice for engineers, machinists, buyers, tradespeople, and hobbyists seeking consistent results in demanding machining tasks.

Key specifications include a cutting diameter range of 1.0 mm to 20.0 mm with a diameter tolerance of +0/-0.03 mm. The tool employs a variable-index flute pattern with dual helix angles (29° and 31°) to reduce chatter and extend tool life, while a gash tooth design helps prevent flute chipping. Constructed from premium carbide and finished with a W coating, it delivers enhanced wear resistance and reliability for mold and die applications. It can machine materials below 55 HRc, including pre-hardened steel, alloy steel, and carbon steel.

• Variable-index four-flute design with dual helix angles: Reduces chatter and vibration for smoother cuts and longer tool life, even on complex profiles.
• Gash tooth geometry for durability: Helps prevent flute chipping under heavy cuts, delivering reliable performance in tough materials.
• W-coated carbide with wide cutting range and tight tolerance: Ensures precise, repeatable results across a broad range of workpieces without swapping tools.

This end mill combines precision, durability, and versatility to improve workflow and part quality in mold and die machining. The stable cutting, extended tool life, and ability to handle common mold steels and pre-hardened alloys help reduce downtime, improve surface finish, and deliver consistent results across jobs.
