- Optimized for feed rates of 0.12-0.20 mm/rev
- Prevents chip recutting and extends tool life
Recommended Applications & Workpiece Materials
The KDZ0370X1.5S060N-HP is optimized for the following material groups and machining scenarios:
| Material Group | ISO Code | Machinability | Recommended Use |
|---|---|---|---|
| Carbon & Alloy Steel | P.1-P.5 | Excellent | Primary application |
| Stainless Steel | M.1-M.3 | Very Good | With adequate coolant |
| Cast Iron | K.1-K.3 | Good | Dry or MQL machining |
| Hardened Steel (<45 HRC) | H.1-H.3 | Good | Reduced speeds recommended |

Application Map by Operation
| Operation Type | Suitability | Conditions |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Standard parameters |
| Blind-Hole Drilling | ★★★★☆ Very Good | Reduce feed 20% at bottom |
| Spot Drilling / Centering | ★★★★☆ Very Good | High speed, low feed |
| Chamfering | ★★★☆☆ Good | Light depth of cut |
| Enlarging / Counterboring | ★★★☆☆ Good | Reduce speed 15% |
Recommended Cutting Conditions
Optimal parameters for the KDZ0370X1.5S060N-HP with HP grade in stable machining conditions:
| Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (P.1-P.3) | 70-110 m/min | 0.12-0.20 mm/rev | 2xD - 4xD |
| Stainless Steel (M.1-M.2) | 56.0-88.0 m/min | 0.12-0.20 mm/rev | 2xD - 4xD |
| Cast Iron (K.1-K.2) | 84.0-132.0 m/min | 0.12-0.20 mm/rev | 2xD - 4xD |
| Hardened Steel (H.1) | 49-77 m/min | 0.12-0.20 mm/rev | 1xD - 2xD |
Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece stability, and coolant delivery. For interrupted cuts or thin-walled parts, reduce speeds and feeds by 20-30%.
Operating Guidelines
- Coolant: High-pressure coolant (70+ bar) recommended for deep-hole applications. Minimum 5% emulsion concentration.
- Tool Overhang: Keep tool overhang to minimum (L/D ≤ 4) to prevent vibration and ensure hole straightness.
- Entry Angle: Use chamfered or pre-drilled entry when possible. For inclined entry, reduce feed by 30% for first 1 mm.
- Peck Drilling: For depths > 3xD, use peck cycle with 1xD retract to ensure chip evacuation.
- Edge Preparation: HP grade features a honed T-land edge (0.05 mm × 20°) for optimal edge strength and finish quality.
- Insert Change: Rotate or index inserts when flank wear reaches 0.3 mm or when surface finish degrades beyond Ra 1.6 μm.
Toolholder Compatibility
The KDZ0370X1.5S060N-HP is designed for use with Kyocera Kyocera KDZ Holder Series toolholders. Compatible holder models include:
| Holder Model | Shank Diameter | Max Depth | Coolant Supply |
|---|---|---|---|
| KDZ-S037 | 5.7 mm | 3xD | Internal |
| KDZ-M037 | 7.7 mm | 5xD | Internal + External |
Ensure proper insert seating and clamping torque (2.5 N·m) to prevent micro-movement during heavy cuts.
