Note: Values are starting recommendations. Adjust based on machine rigidity, coolant application, and workpiece condition. Use water-soluble coolant for steel and stainless steel; dry or compressed air for cast iron.

10. Operating Guidelines

  • Coolant: High-pressure water-soluble coolant (5-8% concentration) recommended for steel and stainless steel machining
  • Entry Angle: Maintain 15-30° approach angle to minimize notch wear
  • Tool Overhang: Keep to minimum possible; max 4× tool diameter for boring applications
  • Insert Change: Inspect after 4-6 hours of cutting time; replace when flank wear exceeds 0.3 mm
  • Edge Preparation: Light hone (0.02 mm) for finishing
  • Workpiece Runout: Ensure TIR < 0.02 mm for optimal tool life and surface finish

11. Toolholder Compatibility

The VNMG160408PQ is compatible with the following ISO-standard toolholders:

  • Recommended Holders: SVJCR/L, SVVCN, MVJNR/L (35° toolholder)
  • Clamp Type: Lever lock or screw clamp (depending on holder design)
  • Holder Material: Alloy steel with hardened pocket (45-50 HRC)
