In 1987, Air Design started to develop a tungsten carbide disk drill scraper and produced 500 prototypes for field testing that year. With some modifications, the scraper product was successfully introduced in the Fall of 1987. Since then they have continued to add new scraper models to fit a wide range of makes and models. Air Design currently produces over 40 varieties of planter and drill disk scrapers, all in-house in Montana.
The tungsten carbide used by Air Design in the manufacturing of scrapers is a high quality unground carbide called Wearcarb™ with Rockwell hardness of RA92, manufactured by a major United States carbide manufacturer. This source has been used almost since the inception of the scraper in 1987.
