Nowhere is PHQ's experience and craftsmanship better illustrated than the diamond set bit range. Mined diamonds have been selected from the same ethical and reliable sources for many years, resulting in consistent characteristics and reliable products. Designs and setting patterns have evolved through constant dialogue and feedback from the best drillers in the world.
Diamond set bits are still the best choice for softer or more abrasive formations, where the highly resistant matrix can retain the diamonds without the compromises required in an impregnated product, where the matrix is expected to erode.
