Quality Control
Every Dennis Tool Company product must pass a rigorous series of quality control procedures that evaluate not only overall dimensional specifications, but also grain structure, surface condition, and internal structural integrity. Skilled technicians use an advanced ultrasonic C-scan procedure to look deep into the structure of PDC materials to ensure that each part is free of internal defects and that the integrity of the interface between the superabrasive layer and the carbide substrate is optimal. PDC products are also subjected to ultraviolet dye penetrant examination, microscopic visual examination, and dimensional inspection using PDC-tipped micrometers and other specialized measuring techniques. Brazed products are inspected using ultrasonic inspection techniques to detect possible internal flaws. Numerous in-process inspections, utilization of computerized process controls, and modern inspection equipment ensure that every product we manufacture complies with specifications. Because our products consistently conform to specifications, our products are self-certified at most of our customers’ facilities — eliminating the need for re-inspection prior to use.

Dennis Tool Company is committed to delivering consistently high-quality PDC products at competitive prices, and devotes an extraordinary level of research and engineering to product development and advanced manufacturing technologies to stay at the forefront of superabrasive material development.
