The P5™ ADM™ Core Bit was engineered with ADM™ (Advance Diamond Matrix) diamond pattern and layering technology. ADM™ optimizes tool performance with a uniform distribution of diamond across the cutting surface and throughout the diamond bond. ADM™ tools cut faster and last longer, with consistent high- performance throughout the life of the tool. Other features of the P5™ Core Bit include: segments that are laser welded to the tool core, vacuum brazed core protection, and cooling slots that improve cooling and provide easier core removal.
