4 Flutes Carbide End Mill Polished Square Cutting End Mill Uncoated For Aluminium

4 Flutes Polished Carbide Square End Mill For Aluminium With Radius

Introduction:

The AMG Customized 4-Flute Square End Mill is a high-efficiency CNC cutting tool specially engineered for aluminum machining, offering exceptional chip evacuation, smooth cutting performance, and extended tool life. Its square end with corner radius enhances edge strength while reducing chipping, making it ideal for high-speed milling (HSM) and heavy roughing/finishing in aluminum alloys.

Features:

Optimized for Aluminum & Non-Ferrous Metals

• High helix angle (35°~45°) for superior chip flow and reduced cutting resistance.

• Polished flutes & sharp cutting edges prevent material adhesion (built-up edge).

4-Flute Design with Corner Radius (R0.2-R1.0mm)

• Higher feed rates & better surface finish compared to 2/3-flute end mills.

• Corner radius (rounded edges) improves tool durability and prevents corner chipping.

Specialized Coating (Uncoated/Non-Stick Option or ZrN/AlCrN)

• Low-friction polished surface for reduced heat & gumming in sticky aluminum alloys.

• Optional coatings (ZrN/AlCrN) for longer tool life in high-speed applications.

High-Performance Carbide Substrate

• Fine-grain carbide for high rigidity & wear resistance in aggressive machining.

• Balanced geometry minimizes vibration for smooth, chatter-free cuts.

Customizable Geometry (Diameter, Flute Length, Helix Angle)

• Tailored for specific CNC applications (e.g., deep-pocket machining, high-speed finishing).

High-Speed Machining (HSM) & Trochoidal Milling Compatible

• Stable performance at 20,000+ RPM (depending on tool size).

Typical Applications:

✔ Aerospace aluminum components (structural parts, fuselage panels)
✔ Automotive (engine blocks, cylinder heads, wheels)
✔ 3C industry (laptop cases, smartphone frames)
✔ Die-cast aluminum molds & general CNC milling

Why Choose This 4-Flute Ball End Mill?

✅ Superior chip evacuation – Prevents clogging in deep slots
✅ Extended tool life – Reduced wear in high-speed aluminum machining
✅ Smooth surface finish – Minimizes post-machining polishing
