PCD Process Step 1 Press Insertion A diamond powder filled carbide blank is inserted into Precorp's high-pressure, high-temperature press and subjected to 2,700 degrees F and 876,000 psi. In this process the diamond powder is compressed and the diamond crystals are bonded to each other and to the carbide nib. Step 2 Form Finalized The PCD nib is then brazed to a solid carbide shank. The braze is located sufficiently away from the tip of the tool. This allows the use of a high-temperature high-strength braze joint between the nib and the carbide shank. Step 3 Form and Shaft Brazed The PCD nib is then brazed to a solid carbide shank. The braze is located sufficiently away from the tip of the tool. This allows the use of a high-temperature high-strength braze joint between the nib and the carbide shank. Step 4 Geometry Finalized The drill geometry is ground to produce the finished PCD tool. This patented process allows for many tool geometries that were impractical and/or impossible using conventional PCD insert process.
