3x3x50L 3-Flute Aluminum Square End Mill
This solid carbide 3x3x50L 3-flute aluminum square end mill is designed for precise CNC machining of aluminum and aluminum alloys. The polished flute geometry reduces friction and supports smooth chip evacuation, helping prevent built-up edge during profiling, pocketing and finishing operations.
Product Specifications
- Cutting diameter: 3 mm
- Shank diameter: 3 mm
- Overall length: 50 mm
- Flutes: 3
- Tool material: Solid carbide
- End style: Square end
- Application: Aluminum and aluminum alloys
The compact 3 mm tool diameter is suitable for fine slots, small contours and detailed aluminum components while the short 50 mm length helps preserve rigidity. The square end supports accurate flat-bottom machining and clean vertical walls. Use low runout, suitable spindle speed and feed, and air blast or coolant to maintain reliable chip removal and consistent surface quality.
Recommended Uses
Suitable for CNC routers, machining centers and engraving machines cutting aluminum plate, profiles and non-ferrous components. The 3-flute design provides a practical balance of rigidity, finish and productivity for everyday aluminum machining.
