Grade Details - Key Grade Characteristics
The HP grade represents Kyocera's high-performance coating technology, specifically developed for solid carbide drills operating in demanding material removal scenarios.
- Substrate: Ultra-fine grain carbide (0.6 μm grain size) for superior edge stability and fracture resistance
- Coating: Multi-layer AlTiN (Aluminum Titanium Nitride) coating with nano-structured architecture
- Coating Hardness: 3,300 HV (Vickers) for exceptional wear resistance at elevated temperatures
- Coating Thickness: 2.5 μm ± 0.3 μm, optimized for cutting edge sharpness retention
- Max Operating Temperature: 900°C (1,652°F) in continuous cutting
- Friction Coefficient: 0.35 against steel, reducing built-up edge formation
- Oxidation Resistance: Excellent up to 850°C, ensuring stable performance in dry machining
Grade Comparison Matrix
| Grade | Coating | Target Material | Speed Factor | Wear Resistance |
|---|---|---|---|---|
| HP | AlTiN Multi-layer | Steel, Stainless, Cast Iron | 1.3x - 1.5x | Excellent |
| CA | TiAlN | General Steel | 1.0x (Baseline) | Good |
| GW | TiSiN | Hardened Steel (>50 HRC) | 1.1x - 1.2x | Very Good |
| PR | TiCN + Al₂O₃ | Cast Iron, Non-ferrous | 1.0x - 1.2x | Good |
Chipbreaker Profile
The KDZ0520X3.0S060N-HP features an optimized flute profile designed for efficient chip evacuation and stable drilling dynamics:
- Flute Form: Parabolic flute geometry with polished surfaces (Ra 0.2 μm) for reduced chip adhesion
- Chipbreaker Type: Continuous helical groove with variable pitch for harmonic vibration damping
- Chip Evacuation: Internal coolant capability (through-tool) with dual coolant holes positioned at 180°
- Coolant Hole Diameter: 0.6 mm per hole, providing high-pressure coolant delivery up to 70 bar
- Surface Treatment: Polished flute and margin lands to minimize built-up edge and improve surface finish

Application Map by Operation
| Operation Type | Suitability | Max Depth | Hole Quality |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 3.0xD | IT8 - IT9 |
| Blind-Hole Drilling | ★★★★☆ | 3.0xD | IT9 - IT10 |
| Stack Plate Drilling | ★★★★☆ | 2.5xD | IT9 |
| Inclined Entry (≤10°) | ★★★☆☆ | 2.0xD | IT10 |
| Cross-Hole Intersection | ★★★☆☆ | 1.5xD | IT10 - IT11 |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 93 | 0.162 | Emulsion / Internal |
| Stainless Steel (304) | 69 | 0.131 | Internal High-Pressure |
| Gray Cast Iron (GG25) | 116 | 0.202 | Dry / Compressed Air |
| Alloy Steel (42CrMo4) | 83 | 0.152 | Emulsion / Internal |
| Tool Steel (H13, 40 HRC) | 68 | 0.142 | Internal High-Pressure |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and coolant delivery efficiency. Reduce Vc by 15% for blind holes and by 20% for inclined entries.
Operating Guidelines
- Spindle Runout: Maintain TIR ≤ 0.01 mm at the tool tip to prevent hole enlargement and premature corner wear
- Tool Overhang: Minimize overhang to 4xD maximum for optimal stability and hole straightness
- Coolant Pressure: For internal coolant tools, ensure minimum 20 bar pressure at the spindle for effective chip evacuation
- Peck Drilling: Recommended for depths > 2.5xD; use 1.0xD peck depth with full retract for chip clearing
- Entry Chamfer: Prepare a 45° chamfer or center drill to ensure accurate tool engagement and prevent walk-off
- Speed Ramp: Accelerate to full Vc within 2 seconds of tool engagement to avoid work-hardening in stainless steels
- Tool Life Monitoring: Monitor flank wear (VB) and replace when VB reaches 0.3 mm or when hole tolerance exceeds IT10
