%X Five general drawings of drilling tools designed by CAD software in Wuhan, Hubei Province from 2017 to 2020, including general drawings of PDC bit, coring bit, impregnated bit, screw drill and turbodrill. The time coverage of resources is from January 1, 2018 to December 30, 2020, and the geographical coverage of resources is Wuhan City, Hubei Province. The 3D model is drawn by using 3D drawing software UG to generate 2D engineering drawings, including the overall structure appearance and overall size of drill bit and drilling tool.
