Product Function

Designed specifically for high-speed machining of non-ferrous metals, our 3 Flute Tungsten Carbide End Mill with Long Cutting Length is the ultimate solution for deep slotting and profiling in Aluminum alloys (6061, 7075), Copper, and Brass.
The unique 3-flute geometry balances large chip evacuation space with core strength, allowing for deep passes without clogging. This tool is engineered to solve the common issue of "chip welding" or sticking when machining aluminum, ensuring a mirror-like surface finish on your workpieces.

Product Features

  • Extended Reach Capability: Features an extra-long flute length (up to 5x-9x diameter ratio), perfect for deep pocketing and wall finishing where standard end mills fail.
  • Mirror Polished Flutes: Special grinding process reduces friction and heat generation, effectively preventing built-up edge (BUE) and chip packing.
  • High-Quality Material: Made from Ultra-Fine Micro Grain Tungsten Carbide (HRC55), offering superior wear resistance and tool life compared to HSS or standard carbide.
  • Vibration Control: Optimized helix angle reduces chatter during deep cutting operations, ensuring dimensional accuracy.
  • Universal Shank: All sizes from 1mm to 4mm cutter diameter come with a robust 4mm shank, providing extra stability and compatibility with standard collets.

FAQ

Q: Can these end mills be used on Steel or Stainless Steel? A: While they are tough, the geometry is optimized for Aluminum. Using them on steel may result in premature wear. We have a dedicated series for Steel/Stainless Steel—please check our catalog.
Q: Do you offer custom sizes not listed in the table? A: Yes! As a manufacturer, we offer OEM/ODM services. If you need a specific length of cut or overall length, please contact our sales team for a quote.
Q: How do you pack the tools? A: Each end mill is packed in a robust plastic tube with label protection to ensure it arrives safely.
