cemented tungsten carbide grade properties

Grade PN90

Hyperion manufactures cemented carbide rotary tool blanks specifically designed to handle the demanding conditions in die and mold machining and other hard steel machining applications, as well as carbon fiber reinforced polymer (CFRP) machining where maintaining a sharp edge is necessary.

Grade PN90 features an ultra fine carbide grain size combined with the most consistent micro structure available in the market today. A proprietary manufacturing process allows for submicron carbide grain size and 9% cobalt content, giving an optimum balance of hardness and edge wear resistance along with bulk toughness to provide long predictable tool life. If you need premium performance in hard steel finishing or the sharpest edge available for CFRP machining, then grade PN90 is the solution you need.

Grade PN90 is recommended for:

  • Finishing of hardened steel
  • High speed milling/drilling of cast iron
  • Machining non-ferrous and light alloys
  • Drilling, milling, and routing of CFRP composite and ceramic filled resin materials
  • Machining paper, wood, and resin laminates.


Grade H10F 

Grade H10F is the market leading 10% sub micron grade of cemented carbide. Consistency and reliability are the major factors to its continued success. Grade H10F offers an excellent combination of strength, toughness, wear resistance, and edge sharpness. 

Grade H10F is recommended for solid carbide rotary tools in an exceptionally wide application range. The consistent microstructure makes grade H10F a superb substrate for today's range of coatings. In addition, a special additive maximizes corrosion resistance without the loss of toughness.

Grade H10F is recommended for:

  • Machining of engineering steels, stainless steels, and titanium and nickel alloys as well as castings of non-ferrous and non-metallic work materials
  • Low cutting speeds, high feed rates (HSS range), and interrupted cutting.


Grade AM70

Grade AM70 is a combination of sub-micron tungsten carbide (Wolfram) grains and binder that provides the perfect mix of toughness and wear resistance. It is recommended in applications where edge integrity is required to prevent corner chipping.  

Grade AM70 was developed to increase drilling productivity performance in alloy steels, as it provides faster penetration rates while maintaining edge security. It has also shown excellent performance in roughing and finish milling applications involving ISO M and titanium materials. The grade has been tested in several aerospace and medical applications to machine titanium materials and has shown tool life increases of 20% to 30%, depending on machine integrity and tool quality.  

Grade AM70 is recommended for:

  • Roughing and finish milling of ISO M and titanium materials.
