Daxer Carbide's GP, HP, and UHP series cover the full range of steel milling applications — from mild steel and 4140 alloy steel to tool steel and hardened materials. AlTiN coating provides excellent heat resistance and wear protection in steel cutting.
Steel milling requires AlTiN or TiAlN coating for heat resistance. Use 4-flute end mills for finishing; consider variable-flute or chipbreaker variants for roughing. Corner radius end mills significantly extend tool life in steel by reducing stress concentration at the cutting edge.
