Beefy 1/2 inch Carbide Roughing End Mill with ZrN/AlTiBN
✔️ 1/2 inch carbide roughing end mill with ZrN+AlTiBN coating

Heavy-duty 1/2 inch carbide roughing end mill designed for tough metalworking tasks. It’s commonly used in CNC milling and fabrication shops for roughing passes in alloy steels, hardened steels, pre-hardened steels, and cast iron.

✅ Works with carbon steels (~HB225), alloy steels (HB225-325), pre-hardened steels up to HRC45, hardened steels (HRC40-45), and cast iron
✅ ZrN + AlTiBN coating provides stability at high temperatures and superior heat resistance vs TiAlN, TiN, or TiCN coatings
✅ Micrograin carbide construction delivers toughness, durability, and easy machinability for long tool life
✅ Fine workmanship with tolerance around -0.02 mm for high accuracy in cutting
✅ Dedicated support via Amazon for Cutting Condition Data to help you pick and apply the right tool
