Advanced ultrahard materials for HPHT drilling

Combining decades of experience with expertise and ingenuity, MegaDiamond provides advanced ultrahard materials that withstand hostile downhole conditions and address your specific application requirements.

HPHT press technology

Our facilities include cubic press, belt press, and piston-cylinder press technologies, which are capable of generating the ultrahigh pressures (800,000 psi) and temperatures (2,700 degF or 1,500 degC) required to sinter polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PCBN) products. This enables us to optimize sintering conditions for each product to obtain the highest quality and maximum performance for any given application.

  • Cubic press—triaxial system particularly suited to sintering products with complex 3D geometries.
  • Belt press—large reaction volume appropriate for large diameter products or multiples of smaller products. Used to produce the first man-made diamonds.
  • Piston-cylinder press—high-pressure capsule contained within the cylindrical bore of a carbide die supported by radial hydraulic pressure, allowing for pressurization of the inside and outside of the die.

Polycrystalline diamond and cubic boron nitride materials

Available for a full range of full-round blanks and precut pieces, our PCD and PCBN materials deliver increased productivity and cost savings over conventional carbide and ceramic tools. Our extensive line of PCD products includes diamond-enhanced inserts for tricone and percussive bits and synthetic diamond cutters for PDC bits.

Bearing products

MegaDiamond bearing products are designed for optimal performance and long life in abrasive environments. Cooling grooves can be added to any product according to your specifications.

Domed inserts

For applications that require high abrasion and impact resistance, we offer domed insert products that incorporate transition layers between the diamond layer and the tungsten carbide substrate for improved impact strength and thermal integrity.

Shear cutters

Available with diameters from 11 to 19 mm and in lengths from 8 to 16 mm, shear cutters are produced with a diamond grade that is effective in most applications requiring high-impact and high-abrasion resistance. The cutters incorporate a unique nonplanar interface design for enhanced performance.
