4x4x50L 2-Flute Aluminum Square End Mill
This solid carbide 4x4x50L 2-flute aluminum square end mill is designed for stable CNC cutting of aluminum and aluminum-alloy workpieces. Its two large polished flutes provide generous chip space, helping evacuate soft, continuous aluminum chips and reducing chip welding during slotting, profiling and pocket machining.
Product Specifications
- Cutting diameter: 4 mm
- Shank diameter: 4 mm
- Overall length: 50 mm
- Flutes: 2
- Tool material: Solid carbide
- End style: Square end
- Application: Aluminum and aluminum alloys
The square cutting end supports flat-bottom machining and accurate wall finishing. The compact 50 mm overall length improves rigidity and helps control vibration, while the 4 mm shank fits common CNC collets. For best results, use adequate air blast or suitable coolant, keep tool runout low, and select spindle speed and feed according to machine rigidity and workpiece alloy.
Recommended Uses
This cutter is suitable for CNC routers, machining centers and engraving machines processing aluminum plate, aluminum profiles and general non-ferrous components. The 2-flute geometry is especially useful for full-width slotting and deeper pockets where reliable chip evacuation is essential.
