4 FLUTE-SOLID CARBIDE, SQUARE END MILL

BFL tungsten carbide flat end mills with 4 flutes and coating are optimized for high hardness machining (HRC55), including copper, cast iron, and mold steels. Manufactured with fine-grain tungsten carbide for superior toughness, with AlTiN and Diamond coatings ideal for high-speed operations due to their heat resistance.

Applications

• High-speed CNC machining in mold and die steels
• Milling of high hardness materials (HRC45–HRC65)
• Fine surface finishing in copper, cast iron, and aluminum alloys
• Roughing and semi-finishing operations in vertical and horizontal machining centers
• Automotive, aerospace, mold manufacturing, and die-making industries
