Grade Details – Key Grade Characteristics
PR1535 is Kyocera’s premium nano-layered PVD-coated ultra-fine grain carbide grade, engineered specifically for high-speed micro-milling of hardened steels and heat-resistant alloys.
- Substrate: 0.3 μm ultra-fine tungsten carbide (WC) with 12% cobalt binder
- Coating: Multi-layer TiAlN + TiSiN nano-composite (3.5 μm total thickness)
- Hardness: 3,600 HV (Vickers) – superior wear resistance
- Oxidation Resistance: Up to 1,100°C – stable performance in dry machining
- Coating Adhesion: HF1 rating (Daimler-Benz test) – prevents delamination under cyclic thermal loads
- Surface Roughness (Ra): <0.05 μm on coating surface – minimizes built-up edge
Grade Comparison Matrix
| Property | PR1535 | PR1525 | PR1705 |
|---|---|---|---|
| Hardness (HV) | 3,600 | 3,400 | 3,200 |
| Coating Type | Nano TiAlN/TiSiN | TiAlN | TiSiN |
| Max Temp (°C) | 1,100 | 950 | 1,000 |
| Best For | Hardened Steel >55 HRC | General Steel <50 HRC | Stainless / Titanium |
| Wear Resistance | ★★★★★ | ★★★★☆ | ★★★☆☆ |
Chipbreaker / Flute Profile
The 3-flute ball-nose geometry incorporates an advanced variable-pitch design with an optimized core-thinning profile to enhance chip evacuation in micro-milling operations.
- Flute Profile: Parabolic gash with polished rake face (Ra < 0.1 μm)
- Rake Angle: 8° positive radial rake, 4° axial rake for reduced cutting forces
- Clearance Angle: 12° primary + 25° secondary clearance – prevents rubbing
- Variable Pitch: 85° / 92° / 93° spacing – suppresses chatter in high-L/D setups
- Edge Preparation: 0.003 mm honed T-land + micro-polished S-cutting edge
- Chipbreaker Geometry: Not applicable (ball-nose endmill); instead, chip-thinning geometry with convex rake land
Recommended Applications & Workpiece Materials

Operating Guidelines
- Run-out Check: Ensure tool run-out at gauge length is < 0.005 mm TIR to prevent premature chipping.
- Pre-Machining: Always pre-drill or ramp-entry; avoid direct plunging with ball-nose endmills.
- Coolant Strategy: Use oil-mist or MQL for hardened steels; avoid water-soluble coolants with high chlorine content.
- Step-over Recommendation: For finishing, keep ae between 3–8% of DC to achieve mirror surface finish.
- Tool Life Indicator: Replace when flank wear (VB) reaches 0.03 mm or when surface finish degrades beyond Ra 0.2 μm.
- Storage: Store in original packaging at 15–25°C, humidity < 60% RH to prevent coating oxidation.
