Ferrous Materials

Coating / Substrate: TiN
Titanium Nitride - C1
Aluminum Titanium Nitride - C3
AlTiN Nano
Aluminum Titanium Nitride Nano - C6
Applications / Benefits:
  • General purpose coating for machining ferrous materials.
  • High performance coating in ferrous materials.
  • Excellent high temperature resistance and hardness.
  • Maintains high surface hardness at elevated temperatures improving tool life and allowing faster feed rates.
  • Produces aluminum oxide layer at high temperature which reduces thermal conductivity, transferring heat into the chip.
  • Excellent in dry machining, machining titanium alloys, inconel, stainless alloys, and cast iron.
  • Premium coating in ferrous materials.
  • Latest generation AlTiN coating mixed with silicon to produce a unique nanocomposite coating. This structure improves hardness, heat resistance, and toughness over traditional AlTiN coatings.
  • Superior results, extended tool life and reduced cycle times over traditional AlTiN coatings in demanding applications where setup minimizes runout and vibration.
  • Not recommended for use in aluminum and aluminum alloys.

Non-ferrous Materials

Coating / Substrate: ZrN
Zirconium Nitride - C7
Titanium Diboride - C8
Amorphous Diamond Diamond-Like Coating - C4 CVD Diamond PCD Diamond
Polycrystalline Diamond
Applications / Benefits:
  • High hardness, lubricity and abrasion resistance.
  • Improves performance over uncoated carbide in a wide variety of non-ferrous materials.
  • Less expensive alternative to diamond.
  • Primary benefit over other non- ferrous coatings is extremely low affinity to aluminum.
  • Prevents build- up on cutting edge, chip packing and extends tool life.
  • Recommended in Aluminum Alloys and Magnesium Alloys.
  • Not ideally suited for abrasive varieties of these alloys.
  • A PVD amorphous diamond coating which improves lubricity and wear resistance in non- ferrous materials.
  • Coating is thin relative to CVD diamond, preventing edge rounding.
  • Sharp edges improve results (performance and finish) over CVD in certain abrasive, non-ferrous materials (copper, brass, high silicon aluminum).
  • Low temperature threshold makes diamond unsuitable for ferrous applications.amorphous diamond
    Thin coating maintains sharper edge.
  • True Crystalline CVD diamond is grown directly into a carbide end mill.
  • Dramatically improves hardness.
  • Hardness improves abrasion resistance and extends tool life up to 50x and allows higher feed rates than uncoated carbide.
  • Ideal for machining Graphite, Composites, Green Carbide, and Green Ceramics.
  • Diamond layer approx 5 times thicker than Amorphous Diamond improving wear resistance.
  • Low temperature threshhold makes diamond unsuitable for ferrous applications.cvd diamond
    Thicker diamond layer for increased wear resistance.
  • PCD diamond is manufactured as a carbide backed flat wafer. The wafer is brazed to a carbide body to form an end mill.
  • PCD has excellent hardness and abrasion resistance, and is the thickest diamond layer we offer.
  • Sharply ground cutting edges and thick diamond layer combine the sharp edge benefits of Amorphous Diamond with the abrasion resistance of CVD Diamond.
  • Low temperature threshhold makes diamond unsuitable for ferrous applications.pcd diamond
    Thickest diamond layer ground to sharp edge.
