Product Function
Our Tungsten Carbide Bull Nose End Mill 2 Flute for Aluminum is specifically engineered for high-speed, high-precision machining of non-ferrous materials. Designed with a micro-diameter geometry, this tool is the ultimate solution for:
- Precision Mold Making: Creating smooth curved surfaces and fillets in aluminum molds.
- 3C Electronic Components: Fine detail processing for phone cases, heat sinks, and delicate aluminum parts.
- Corner Strengthening: The bull nose (corner radius) design offers higher tool strength compared to square end mills, preventing chipping at the corners during high-speed cutting.
- Chip Evacuation: The 2-flute design with a large helix angle ensures rapid chip removal, preventing aluminum from sticking to the cutter (built-up edge).
Product Features
- Premium Material: Made from Ultra-Fine Micro Grain Tungsten Carbide (HRC55), offering exceptional wear resistance and hardness.
- Aluminum Specific Geometry:
- Polished Flutes: Mirror-like finish reduces friction and ensures smooth chip evacuation, critical for soft, gummy materials like aluminum.
- Reinforced Corner: The bull nose radius protects the cutting edge, extending tool life significantly compared to sharp corner tools.
- High Precision: Tolerance controlled within micro-levels, ensuring dimensional accuracy for intricate workpieces.
- Standard Shank: All micro cutter diameters feature a robust 4mm shank, providing stability and reducing vibration during machining.

FAQ
Q1: Is this end mill suitable for Steel or Stainless Steel?
A1: This specific 2-flute design is optimized for Aluminum, Copper, and Plastics. For Steel or Stainless Steel, we recommend our 4-Flute AlTiN coated series.
Q2: What is the tolerance of the shank diameter?
A2: Our standard shank tolerance is h6 (0/-0.008mm), ensuring a perfect fit in high-precision collets.
Q3: Can I mix different sizes to reach the USD500 requirement for the coupon?
A3: Yes! You can mix any sizes and types of cutting tools in your first order to qualify for the USD50 discount.
Q4: How do you pack these micro end mills?
A4: Each micro end mill is individually packed in a robust plastic tube with foam protection to prevent damage to the delicate cutting edges during transit.
