Copper Coating Carbide End Mill 4mm - 32mm 3 Flute End Mills For Carbon Steel

3 flutes carbide square end mill for carbon steel with copper coating

Introduction:

Optimized for high-efficiency steel machining, this 3-flute solid carbide end mill combines aggressive cutting geometry with a proprietary copper-based coating for reduced friction, improved heat dissipation, and exceptional tool life in hardened steels (up to HRC 50).

Features:

3-Flute Design – Ideal balance of chip clearance and edge strength for steel

Copper-Enhanced Coating – Lowers cutting temperatures

Square End (90°) – Sharp corners for shoulder milling and slotting

Variable Helix (35°/40°) – Eliminates harmonics and chatter in tough materials

High-Precision Grinding – ±0.005mm tolerance for critical dimensions

Typical Applications:

• Mold & Die – Core/cavity machining (P20, H13)

• Automotive – Transmission gears, forged components

• General Engineering – Structural steel, alloy shafts
