Attention:
Always use the minimum pre-drill ⌀ to match the slot width (e.g. for slot width 14 mm, minimum pre-drill ⌀ = 38.22 mm).
Note:
Individual holder sizes are for different slot widths. In such cases, where possible, always use the optimum combination of holder and cutting insert (identical size) for maximum stability.For lathes without Y-axis, please use eccentric bush No. 290391− 290393 for exact setting of the Y-coordinate.For machining centres, use the alignment aid No. 290397 and a dial indicator to check the spindle orientation.
