Form Instructions 1. The applicable standard holder depends on the seat size. Refer to the chart on the right for manufacturable seat sizes and corner radius range for facing. (If using a corner radius exceeding this for facing, modication is required to prevent the holder from interfering with the work material.) 2. The corner radius maximum value for external turning and internal boring is 1/2 the width of cut. 3. Seat Size (CW) tolerance is ±0.025mm when manufactured. 4. WF dimensions for each holder are the CWS value for the applicable holder standard insert seat size as follows. (Standard holder dimension WF) + (WF - CWS ) / 2 5. For inch widths of cut, inserts can also be supplied partially unground. Contact your local sales engineer for details.
