4. Grade Details — Key Grade Characteristics
The PR1725 substrate is a micro-grain carbide grade developed by Kyocera for universal machining applications. Key characteristics include:
- Substrate: Ultra-fine tungsten carbide (0.5 μm grain size) with 10% cobalt binder
- Coating: Multi-layer PVD TiAlN coating (2.5 μm thickness) for enhanced heat resistance up to 900°C
- Hardness: 1,650 HV (92.5 HRA) — excellent wear resistance in high-speed applications
- TRS: 4,200 MPa — superior toughness for interrupted cuts
- Thermal Conductivity: 50 W/m·K — efficient heat dissipation from cutting edge
- Oxidation Resistance: Stable performance up to 900°C continuous cutting temperature

|---|---|---|---|
| Slot Milling | Primary | 0.05 – 0.20 × D | Optimal surface finish & accuracy |
| Profile Milling | Secondary | 0.20 – 0.50 × D | Balanced MRR and tool life |
| Pocketing | Conditional | 0.30 – 0.60 × D | Light depths only; check spindle load |
| Plunge Milling | Limited | — | Maximum 0.5×D plunge depth |
9. Recommended Cutting Conditions
Values below are starting recommendations for stable setups with adequate coolant delivery. Adjust based on machine rigidity and workpiece clamping.
| Workpiece Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | ae (mm) |
|---|---|---|---|---|
| Carbon Steel | 111 | 0.0200 | 1.22 | 0.65 |
| Stainless Steel | 85 | 0.0150 | 1.22 | 0.65 |
| Cast Iron | 138 | 0.0250 | 1.22 | 0.65 |

| Hardened Steel (45-55 HRC) | 56 | 0.0100 | 1.22 | 0.65 |
10. Operating Guidelines
- Run-Out Check: Ensure tool run-out is < 0.005 mm (0.0002") at the tool tip to prevent uneven wear.
- Coolant: Flood coolant or high-pressure through-spindle (minimum 70 bar) is recommended for chip evacuation.
- Entry Strategy: Use helical or ramp entry; avoid straight plunging with ball-nose tools.
- Speed Ramp-Up: Start at 70% of recommended Vc and increase in 10% increments while monitoring spindle load.
- Tool Life Indicator: Replace tool when flank wear (VB) exceeds 0.15 mm or when surface finish degrades beyond Ra 0.8 μm.
- Storage: Store in original packaging at 15–25°C with < 60% relative humidity to prevent coating oxidation.
11. Toolholder Compatibility
| Holder Type | Compatible | Notes |
|---|---|---|
| ER Collet Chuck (ER11 / ER16) | Yes | Recommended for diameters ≤ 0.125"; ensure collet cleanliness |
| Shrink Fit Holder | Yes | Best rigidity and run-out control for high-speed finishing |
| Hydraulic Chuck | Yes | Excellent damping for long-overhang applications |
| Weldon Side-Lock | No | Not recommended for micro-diameter tools due to clamping stress |
