Grade Details - Key Grade Characteristics
The HP grade is a high-performance substrate featuring a Nano-layer PVD multi-layer coating deposited via advanced PVD technology. This grade is specifically formulated for high-speed drilling in steels, stainless steels, and cast irons.
| Property | Value | Significance |
|---|---|---|
| Coating Type | Nano-layer PVD | Superior oxidation resistance up to 900°C |
| Hardness (HV) | 1690 HV | Exceptional wear resistance |
| Transverse Rupture Strength | 3302 N/mm² | High mechanical stability under load |
| Friction Coefficient | 0.35 – 0.45 | Reduced built-up edge, smooth chip flow |
| Thermal Conductivity | 45 W/m·K | Efficient heat dissipation from cutting edge |
Grade Comparison Matrix
| Grade | Coating | Speed Capability | Wear Resistance | Best For |
|---|---|---|---|---|
| HP | Nano-layer PVD | High (120–180 m/min) | ★★★★★ | Steel, Stainless, Cast Iron |
| CA | TiAlN | Medium (80–140 m/min) | ★★★★☆ | General-purpose steel |
| PR | TiCN | Medium-High (100–160 m/min) | ★★★★☆ | Mild steel, cast iron |
| GW | AlCrN | Very High (150–250 m/min) | ★★★★★ | Hardened steel, high-temp alloys |
Chipbreaker Profile
The HM-type chipbreaker geometry is optimized for the 8.9mm diameter range. It features a dual-land design with a polished rake surface and a precisely ground groove that promotes tight curling and controlled chip evacuation. This profile minimizes chip recutting, reduces cutting forces by approximately 15%, and ensures stable machining even at elevated feed rates.
| Chipbreaker | Rake Angle | Chip Form | Feed Range |
|---|---|---|---|
| HM | 12° | 6–9 mm C-shaped | 0.10 – 0.25 mm/rev |
Recommended Applications & Workpiece Materials
The KDZ0890X3.0S100N-HP is recommended for the following materials and application scenarios:
- Cast Iron (GG25, GG30) — Excellent chip control and surface finish
- Tool Steel (H13, D2) — High wear resistance for prolonged cuts
- Structural Steel (S235, S355) — Stable performance under intermittent cutting
- Carbon Steel (C45, C60) — Balanced speed and feed capability
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Ideal for blind and through holes up to 10×D |
| Blind-Hole Drilling | ★★★★☆ | Use reduced feed for bottom exit |
| Stack Drilling | ★★★☆☆ | Ensure rigid clamping and peck cycle |
| Enlarging / Counterboring | ★★★★☆ | Reduce speed by 20% for pre-drilled holes |
| Trepanning | ★★☆☆☆ | Not recommended; use dedicated trepanning tools |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Recommended RPM |
|---|---|---|---|
| Carbon Steel (C45) | 121 | 0.14 | 4327 |
| Stainless Steel (304) | 87 | 0.14 | 3111 |
| Cast Iron (GG25) | 120 | 0.18 | 4291 |
| Aluminum Alloy (6061) | 224 | 0.23 | 8011 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece condition. Use internal coolant (10–15 bar) for best performance.
Operating Guidelines
- Coolant: Flood or high-pressure internal coolant (minimum 10 bar) is strongly recommended to extend tool life and improve chip evacuation.
- Peck Cycle: For holes deeper than 3×D, employ a peck drilling cycle with 1–1.5×D peck depth and full retract to break chips.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent uneven insert loading and premature wear.
- Pre-Drilling: For diameters above 12mm, a pilot hole of 0.5×D is recommended to reduce initial thrust force.
- Speed Ramp: Reduce cutting speed by 15–20% for the first 50 holes to allow the coating to burnish and stabilize.
- Insert Torque: Tighten insert screws to 2.5–3.0 N·m using a torque screwdriver to prevent loosening under vibration.
Toolholder Compatibility
The KDZ0890X3.0S100N-HP is compatible with Kyocera ST32 series toolholders and standard cylindrical shank adapters. The shank diameter of 11.1mm ensures a precise fit in ST32-grade collets and hydraulic chucks.
| Holder Series | Clamping Method | Max RPM | Coolant Option |
|---|---|---|---|
| ST32-D | Hydraulic Chuck | 15,000 | Internal + External |
| ST32-C | ER Collet (ER32/ER40) | 12,000 | External |
| ST32-S | Shrink Fit | 20,000 | Internal |
