About this item

  • Material: Cnc 4 Flute Carbide Ball end milling Bit excel at working carbon steels, alloy steels, pre-hardened steels, hardened Steels, cast iron,etc.
  • AlTiN Coating: Titanium aluminum nitride (AlTiN) coating lubricates the end mill for stability at high temperature and superior wear resistance at high cutting speeds, offering better heat resistance than TiAlN, TiN or TiCN coatings.
  • High Performance: carbide has higher hardness and wear resistance and excellent cutting performance than high-speed steel.
  • Durable: HRC 55 Deg,Excellent performance in hard materials that are difficult to cut. Extremely hard, wear resistant.
  • Package Included: 1/4" Extra Long (1 Pieces)

This left a good finish. I’ve only had it once so I cannot speak for longevity.

This is a good quality bit. It fit my CNC perfectly. It seems durable, as I did not notice much wear after multiple passes. The bit performs well through most materials. Overall a good value!

I used this 1/8" extra-long carbide ball nose end mill for some detailed CNC machining on alloy and hardened steels. The extended 3" length was perfect for reaching into deeper pockets without compromising on precision. The 4-flute design provided a smooth cut, and the AlTiN coating ensured durability and heat resistance. This end mill performed exceptionally well, making it a solid choice for high-precision work on tougher materials.
