Form instructions

1. The applicable standard holder depends on the width of cut. Refer to the chart on the right for manufacturable widths of cut and nose radius range for facing. (If using a nose radius exceeding this for facing, modi‰cation is required to prevent the holder from interfering with the part material.) 2. The nose radius maximum value for external/internal diameter machining is 1/2 the width of cut. 3. Width of cut (CW) tolerance is ±0.025mm when manufactured. 4. WF dimensions for each holder are the CWS value for the applicable holder standard insert width of cut as follows. (Standard holder dimension WF) + (WF - CWS ) / 2 5. For inch widths of cut, inserts can also be supplied partially unground.
