I am an undergraduate research assistant at the University of Minnesota Duluths Center for Economic Development. I am currently conducting some research on the US hole saw industry. Specifically I would like to find the numbers of hole saw sold and their distribution channels used to sell to plumbing, heating, and eletrical contractors. Does anyone have any advice on where to come up with this data? From waht I already have found, the major players ae; Lenox, MK Morse, Milwaukee, DeWalt, Starrett, and Greenfield. Advice????
