Webure DP-2c, a more aggressive bit will drill faster because any given WOB will cause it to indent to a greater depth of cut (DOC) per revolution. When operating efficiently, rock strength and bit aggressive-ness effect the drill rate, but large changes in drill rate are usually due to inefficiency or dysfunction in the rock cutting process. WebThe top surface joining the two sides, or flanks. P = Pitch, mm, or threads per inch (t.p.i.) The distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis. β = The thread profile angle. The angle between the flanks of the thread measured in an axial plane.
