A device 10 and method for forming a non-tapered end 12 of a gypsum board 14 into a tapered configuration 16 includes a rotary drive tool 18 that imparts rotary motion to a tool bit 20 removably secured thereto, a pair of oppositely disposed angle members 22 having cooperating base portions 24 configured to promote attaching a dust collection collar 17 to the base portions 24, the angle members 22 disposing and guiding the rotating tool bit 20 between outer paper walls 28 of a non-tapered end 12 of the gypsum board 14 to ultimately severe portions of gypsum from the non-tapered end 12 thereby forming a recess 32 without damaging the paper walls 28, the tool bit 20 removing the severed portions of gypsum from the recess 32 via a spiral channel 34 circumferentially disposed about the tool bit 20, and a vacuum system 36 that removes the severed portions of gypsum from the gypsum board 14 when the tool bit 20 “lifts” the severed portions form the recess 32 whereby the non-tapered end 12 is forcibly bent to form a tapered configuration upon the securing of the non-tapered end 12 to a support structure.
