Micro Tungsten Carbide Bull Nose End Mill 2 Flute for Aluminum | High Precision CNC Bits - Changzhou QT TOOLS

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.
