Recommended Applications & Workpiece Materials
- Carbon steels (C15 – C60, 1010 – 1060)
- Alloy steels (4140, 4340, 8620 in normalized or quenched & tempered condition)
- Tool steels (H13, D2, O1 at hardness ≤ 45 HRC)

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★★ Excellent | Primary application; continuous or light interrupted |
| Internal Turning (Boring) | ★★★★☆ Very Good | Use with minimum overhang toolholders |
| Facing | ★★★★★ Excellent | Stable at high cutting speeds |
| Profiling & Contouring | ★★★★☆ Very Good | Small nose radius variants ideal for fine details |
| Grooving & Parting | ★★☆☆☆ Limited | Not recommended; use dedicated groove inserts |
| Threading | ☆☆☆☆☆ Not Suitable | Use dedicated thread inserts (e.g., 16ER/16IR) |
Recommended Cutting Conditions
Starting parameters for wet and dry machining of steel. Adjust based on machine rigidity and workpiece condition:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Low-Carbon Steel (<0.25% C) | 120 - 250 | 0.10 - 0.35 | 0.5 - 3.0 |
| Medium-Carbon Steel (0.25-0.60% C) | 120 - 250 | 0.10 - 0.35 | 0.5 - 3.0 |
| High-Carbon Steel (>0.60% C) | 102 - 212 | 0.10 - 0.35 | 0.5 - 3.0 |
| Alloy Steel (Annealed) | 96 - 200 | 0.10 - 0.35 | 0.5 - 3.0 |
| Stainless Steel (Austenitic) | 84 - 175 | 0.10 - 0.35 | 0.5 - 3.0 |
Operating Guidelines
- Coolant: High-pressure coolant (70+ bar) recommended for chip evacuation and thermal management. Use water-miscible cutting fluid with 8-10% concentration.
- Entry Strategy: Avoid direct plunge into workpiece. Use ramp entry or reduce feed by 50% for first 2 mm of engagement.
- Tool Overhang: Keep overhang-to-diameter ratio ≤ 4:1 for boring; ≤ 6:1 for external turning to minimize vibration.
- Edge Preparation: GK chipbreaker features honed T-land (0.05 mm × 20°) for edge stability. Do not re-hone.
- Insert Change: Index insert when flank wear (VB) reaches 0.3 mm or when surface finish degrades beyond Ra 1.6 μm.
- Storage: Store in original packaging at humidity <60% RH. Avoid contact with corrosive agents.
Toolholder Compatibility
The DCMT070204GK is designed for ISO-standard toolholders with the following clamp systems:
- Compatible Holders: DDJNR/L, DDNNR/L, PDJNR/L (55° rhombic seat)
- Clamping Method: Lever lock (L) or Top clamp (T) with through-coolant capability
- Seat Angle: 7° clearance (negative seat pocket for positive insert geometry)
- Coolant Delivery: Internal coolant via toolholder channel (recommended for high-speed operations)
