P: Hole depth (depth of hole and countersink - without drill
point and center point)
W: Point angle – default: 180°
R: Countersinking diameter
U: Countersinking depth
E: Countersinking angle
I: Thread diameter
J: Thread depth
K: Thread runout length
F: Thread pitch
V: Left-hand or right-hand thread - default: 0
■ V=0: Right-hand thread
■ V=1: Left-hand thread
A: Angle – angle of the hole (reference: positive Z axis)
■ Front (range: –90° < A < 90°) – default: 0°
■ Back (range: 90° < A < 270°) – default: 180°
