Single-edged gun drill (hereinafter referred to as gun drill) is used to process deep holes with a diameter of 140mm and a length-to-diameter ratio of 100250 times. It is currently the only method for processing small diameter deep holes with a diameter of 16mm. The accuracy of machining holes can be stabilized at IT 810, and individual ones can reach IT67; the surface roughness can be stabilized at Ra12.53.2m ( 3 5), and individual ones can reach Ra0.8 0.4m steel pipe for structure manufacturers steels Hole drilling Drill Pipe and Heave Weight Drill Pipe steel pipe for structure manufacturers steels Hole drilling - Enpro Pipe2 3/8, 2 7/8 and 3 1/2 Drill Pipe for Common Use.
