Chipbreaker Profile
Standard Negative Geometry
The CNMG120408 features a precision-ground chipbreaker geometry optimized for cnc turning. The carefully calculated groove width and land angle promote controlled chip curling, reduced cutting forces, and minimal heat generation at the tool–workpiece interface.
- Chip Control: Excellent chip breaking across wide feed-rate ranges
- Edge Strength: Reinforced cutting edge for stable machining
- Surface Finish: Polished rake face minimizes built-up edge (BUE)
- Heat Dissipation: Optimized land width for efficient thermal management

Application Map by Operation
| Operation | Suitability | Depth of Cut (ap) | Notes |
|---|---|---|---|
| External Turning | ★★★★★ | 0.5–6.0 mm | Primary application |
| Internal Turning / Boring | ★★★★☆ | 0.5–4.0 mm | Use with suitable boring bar |
| Facing | ★★★★★ | 0.5–5.0 mm | Excellent chip evacuation |
| Profiling / Contouring | ★★★★☆ | 0.3–3.0 mm | Smooth entry/exit |
| Grooving / Parting | ★★☆☆☆ | — | Not recommended |
Recommended Cutting Conditions
Parameters are indicative; always optimize based on machine rigidity, workpiece material, and coolant delivery.
| Operation | Vc (m/min) | f (mm/rev) | ap (mm) | Coolant |
|---|---|---|---|---|
| General Turning | 150–300 | 0.10–0.35 | 1.0–4.0 | Wet/Dry |
| Profiling | 140–260 | 0.08–0.25 | 0.8–3.0 | Wet |
Operating Guidelines
- Tool Setup: Ensure insert seat is clean and free of chips before clamping. Use calibrated torque for clamping screws (typically 2.5–3.5 N·m).
- Run-in Period: For new inserts, reduce cutting speed by 15–20% for the first 5 minutes to stabilize the cutting edge.
- Coolant: Flood coolant is recommended for steel and stainless steel to control thermal cracking. For cast iron, dry machining is acceptable.
- Inspection: Check flank wear (VB) every 30–50 min of cutting time. Replace insert when VB exceeds 0.3 mm or when chipping is observed.
- Storage: Store inserts in original packaging away from moisture and direct sunlight. Avoid contact between inserts to prevent edge damage.
