Custom Special-Shaped Punches — Drawing Notes That Speed Up Quote

Non-standard punches fail in quoting when the drawing omits one critical view. Include at minimum: 1. **Plan and section views** — cross-section shape with all dimensions. For hex, mark across-flats, not corner-to-corner. 2. **Material and hardness** — e.g. SKD11 HRC 58–62, or "same as sample." 3. **Tolerance block** — default ±0.005 mm unless specific features need ±0.002 mm. Mark tight features individually. 4. **Surface finish** — ground OD, EDM finish on shaped head, or polish Ra value. 5. **Quantity and sample requirement** — 1pc sample before batch is common; state it on the RFQ. Acceptable file formats: STEP, IGES, DWG, DXF, PDF. A clear PDF with dimensions is enough to start. Physical samples can be measured and confirmed with a product drawing before production. YZX Precision returns quotes within 2 hours during business hours once the drawing is complete.
