Grade Comparison Matrix
| Grade | Primary Materials | Best Use Case | Wear Resistance | Value Rating |
|---|---|---|---|---|
| PR1725 | Steel / Heavy Duty | Large diameter | ★★★★★ | ★★★★☆ |
| PR1535 | Steel / High Speed | General purpose | ★★★★☆ | ★★★★★ |
| PR930 | Steel / Stainless | Light to medium | ★★★☆☆ | ★★★★★ |
Chipbreaker Profile
The KDA1180X03S120N features a precision-ground heavy-duty chipbreaker optimized for 11.8 mm drilling applications. The groove geometry promotes tight chip curling and controlled evacuation, preventing chip packing in deep-hole operations. The polished rake surface minimizes built-up edge (BUE) when machining sticky materials such as low-carbon steels and austenitic stainless steels.
- Rake Angle: 8° positive for reduced cutting forces
- Chipbreaker Width: Proportional to feed rate (0.15–0.35 mm/rev)
- Chip Form: C-type / 6-type (short spiral, easy evacuation)
- Surface Finish: Mirror-polished flanks (Ra < 0.4 µm)
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommended Grade |
|---|---|---|---|
| Carbon Steel (low/med/high) | P1.1 – P2.5 | ★★★★★ Excellent | PR1725 (optimized) |
| Alloy Steel (Cr, Ni, Mo) | P3.0 – P4.0 | ★★★★☆ Very Good | PR1725 |
| Stainless Steel (austenitic) | M1.0 – M2.0 | ★★★★☆ Very Good | PR1725 |
| Cast Iron (gray/ductile) | K1.0 – K3.0 | ★★★☆☆ Good | PR1725 (light cuts) |
| Tool Steel (hardened < 45 HRC) | P5.0 – P6.0 | ★★★☆☆ Good | PR1725 (preferred) |
Application Map by Operation
| Operation Type | Suitability | Depth Ratio (L/D) | Notes |
|---|---|---|---|
| Through-hole Drilling | ✓ Ideal | Up to 5×D | Standard peck cycle recommended |
| Blind-hole Drilling | ✓ Ideal | Up to 3×D | Use reduced feed near bottom |
| Step Drilling | ✓ Suitable | Up to 2×D per step | Allow 0.5 mm overlap |
| Counter-boring | △ Possible | Up to 1×D | Reduce speed by 20% |
| Enlarging / Reaming | ✗ Not Recommended | — | Use dedicated reaming inserts |
Recommended Cutting Conditions
Parameters below are starting recommendations for carbon steel (P2.0) using coolant. Adjust based on machine rigidity and workpiece fixturing.
| Parameter | Symbol | Minimum | Recommended | Maximum | Unit |
|---|---|---|---|---|---|
| Cutting Speed | Vc | 60 | 90 | 120 | m/min |
| Feed per Revolution | fn | 0.12 | 0.21 | 0.3 | mm/rev |
| Depth of Cut | ap | 3.0 | 5.9 | 7.1 | mm |
| Spindle Speed (approx.) | n | 1618 | 2428 | 3237 | rpm |
Operating Guidelines
- Coolant: High-pressure coolant (≥ 3 MPa) is strongly recommended for chip evacuation and temperature control. Use water-soluble coolant at 8–10% concentration.
- Peck Cycle: For depths exceeding 2×D, employ a peck drilling cycle with 0.5–1.0 mm retract to break chips.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent insert chipping and uneven wear.
- Pre-drilling: For 11.8 mm holes, a center drill or spot drill of 90°–120° is recommended to guide the insert.
- Tool Life Check: Monitor flank wear (VB). Replace insert when VB reaches 0.3 mm or when surface finish degrades.
- Storage: Keep inserts in original packaging away from direct sunlight and corrosive environments.
Toolholder Compatibility
The KDA1180X03S120N is designed for use with Kyocera KDA series drill holders and compatible indexable drill bodies. Ensure the holder pocket matches the insert size class (120N). Compatible holder families include:
- Kyocera KDA-S series steel shanks
- Kyocera KDA-M series modular heads
- Standard ISO-compliant drill bodies with KDA pocket geometry
Mounting Torque: 2.5 N·m for clamp screws (M2.5). Do not overtighten to avoid insert fracture.
