The fundamental basis of above average performance for RDTI, in the long run, is maintaining a sustainable competitive advantage. Our strength is product differentiation due to the availability of our unique product offerings including the Beveled Edge Disc (BED) System, Cup Wheels including S-Seg, H-Seg, and J-Seg, and Speed Shift Plates and Diamond discs. Due to the unique shape and design of the aforementioned products we are able to increase our customers profits by lowering labor costs and increasing product longevity.

Based on the success of the BED System and the Cup Wheels, and especially the “Speed Shift” system RDTI will continue to leverage product differentiation. In this differentiation strategy, we will seek to continue to be unique along these dimensions because they are widely valued by our customers. We will choose one or more attributes that many of our buyers perceive as important, and uniquely position ourselves to meet those needs. 

The logic of the differentiation strategy requires that our firm choose attributes in which to differentiate itself that are different from our rivals'. Our firm is truly perceived as unique and we expect to receive a premium price. RDTI owner, Jonathan Thompson, (an end-user for many years), has the knowledge and expertise required to continue to leverage product differentiation via product innovation. Mr. Thompson brings more than 35 years of diamond product knowledge and a unique end-user perspective to RDTI. He is aware of what will and will not work in the field.
