Recommended Cutting Conditions

Parameters below serve as starting points. Optimize based on machine rigidity, coolant delivery, and workpiece condition:

Material Cutting Speed (m/min) Feed (mm/rev) Depth of Cut (mm)
Low Carbon Steel180 - 2500.15 - 0.350.5 - 3.0
Medium Carbon Steel150 - 2200.12 - 0.300.5 - 2.5
Alloy Steel120 - 1800.10 - 0.250.5 - 2.0
Stainless Steel100 - 1500.10 - 0.200.3 - 1.5

Values shown for stable setups with high-pressure coolant. Reduce speed by 20% for dry machining or low-rigidity setups.

Operating Guidelines

Follow these best practices to maximize tool life and part quality:

  • Always use adequate coolant flow (minimum 5% concentration) for steel machining
  • Ensure rigid toolholder setup to minimize vibration and maximize tool life
  • Reduce cutting speed by 15% when entering interrupted cuts or scale-covered surfaces
  • Maintain consistent feed rates to prevent built-up edge formation
  • Inspect insert seating surface before mounting to ensure flat contact
  • Use torque wrench for clamping screws to manufacturer specification (2.5-3.5 Nm)
  • Replace insert when flank wear reaches 0.3 mm or crater wear exceeds 0.15 mm

Toolholder Compatibility

This insert is compatible with standard 60° triangular toolholders designed for positive inserts:

Toolholder Series Style Compatibility
STGCR / STGCLExternal TurningDirect Fit
STWCR / STWCLExternal TurningDirect Fit
SCLCR / SCLCLBoring BarDirect Fit
