Square End Mill – DLC/U Composite Coated Series For Alu & Copper

Flat End Mill – DLC/U Composite Coated Series For Alu. & Copper

Core Positioning & Design Concept

Designed exclusively to solve the core challenge of “material stickiness” in machining non-ferrous metals like aluminum and copper, this is a high-end tool for finish machining and semi-finish machining. Its core goals are to achieve anti-adhesion (no built-up edge), mirror-like surface finish, while ensuring machining stability and long tool life.

Key Feature Analysis

• Fancy Dark (Special PVD Coating)

  It presents dark tones such as black or dark gray with iridescent highlights. Its core function is extreme anti-adhesion: the ultra-smooth surface with low friction coefficient prevents aluminum/copper molecules from welding to the tool edge, eliminating built-up edge entirely. It also has high hardness to protect the cutting edge and extend tool life.

• U-Flute for Al & Cu

  Equipped with wide U-shaped chip flutes, it quickly evacuates chips during finish machining to avoid scratching the already machined surface. The tool body, flute design, and cutting edge are all optimized for aluminum and copper, ensuring perfect machining adaptability.

• Flat-End Mill Structure

  It retains all functions of a standard flat-end mill: machining 90° vertical side walls, precision milling of large flat surfaces, and supporting operations like corner cleaning and grooving, meeting diverse finish machining needs.

ypical Applications

• Finish machining of precision mold cavities (aluminum die-casting molds, plastic molds, glass molds)
• Machining of optical product molds (lens molds, light guide plates)
• High-gloss chamfering of aluminum parts (smartphone middle frames, laptop casings)
• Finish machining of copper electrodes (for EDM processing)
• Bright milling of high-end aluminum components
