Product Function

Engineered specifically for Non-Ferrous Materials, this 2-Flute Solid Carbide Ball Nose End Mill features a specialized Mirror Polished flute surface. It is the ideal solution for high-speed 3D contouring and profiling of Aluminum Alloys (6061, 7075), Copper, Brass, and Plastics.
The "Decimal" Advantage: This series offers a comprehensive range of Decimal Radii (e.g., R1.05, R1.18, R3.175). This is crucial for:
  • Mold Making: Creating precise radii in shoe molds and bottle blowing molds without custom grinding.
  • 3C Electronics: Machining complex curved surfaces on aluminum phone cases and heat sinks.

Product Features

  1. Mirror Polished Flutes: We utilize a unique grinding process to achieve a mirror-like finish. This minimizes friction and effectively prevents Built-Up Edge (BUE), ensuring chips slide off easily.
  1. Sharp Cutting Edge: Unlike steel tools which have honed edges, our aluminum series features a razor-sharp edge to shear through soft materials cleanly, leaving a burr-free surface.
  1. Deep Gullet Design: The 2-flute geometry provides maximum chip space, allowing for high feed rates and efficient chip evacuation during deep cavity milling.
  1. Uncoated / Bright Finish: Typically supplied uncoated to maintain the sharpest possible edge. (DLC - Diamond-Like Carbon coating available upon request for extreme wear resistance).
  1. Wide Size Range: From micro R1.05 to R4.5, covering all your precision detailing needs.

RPM/Feed Reference Table (For Aluminum Alloys)

Note: Aluminum allows for much higher speeds than steel. High RPM is recommended to achieve a glossy surface finish.

FAQ

Q: Are these tools coated? A: No, they are Uncoated and Mirror Polished. This is the standard for Aluminum to ensure the sharpest cutting edge. If you need DLC (Diamond-Like Carbon) coating for extended life in abrasive aluminum, please contact us for a custom quote.
Q: Can I use this on Acrylic or Plastics? A: Yes! The sharp edge and polished flute make this tool excellent for Acrylic (PMMA), Polycarbonate, and other plastics, leaving a clear, transparent finish.
Q: Is R3.175 compatible with 1/8" collets? A: The cutting radius is R3.175 (1/8"), but please note the shank diameter is 8mm. You will need an 8mm collet to hold this tool.
Q: What is the runout tolerance? A: We guarantee a runout of less than 0.005mm to ensure balanced cutting at high RPMs.
