PLUNGING CUTTERS USER GUIDE TANGPLUNGE PLUNGING LINE When plunging starts from a pre-drilled hole, the initial diameter of the hole Di should be larger than the plunger diameter Dt. Note: After each axial plunge stroke, move 45° from the horizontal, a distance of at least 0.5 mm. Only after this move can you move up and away for a rapid exit. See Sketch 6. Sketch 5 The PLH...- type (trepanning) plungers have a hollow center. This requires a specific pattern so the column that remains after each plunge is removed completely and smoothly. The coordinates in Table 1 produce the pattern shown in Sketch 7. This provides the optimal results for the PLH D75-27-13 type plunger (outer diameter of 75 mm, inner diameter of 24 mm).
