Newly patented Encore Bits process is announced to selectively leach portions of PDC cutters already mounted in drill bits. It involves coating the entire PDC cutter with an acid-resistant film, then removing the film from portions of the cutter where leaching is preferred. The cutter is then bathed in acid to remove the cobalt-catalyzing material.
The new process allows this manufacturer to only leach the drilling edge of the cutter. This provides both a wear-resistant edge where the cutter is doing the work — along with a more impact-resistant cutter face, declares the company. Complete process and bits information is yours free upon request.
