Grade Details - Key Grade Characteristics
The PR1535 substrate is an ultra-fine grain carbide (0.5 μm grain size) combined with a multi-layer PVD coating (TiAlN + TiSiN). This composition provides:
- Exceptional hardness of 92.5 HRA for superior wear resistance
- Oxidation resistance up to 1,100°C enabling elevated cutting speeds
- Low coefficient of friction minimizing built-up edge formation
- High transverse rupture strength (3,800 MPa) for micro-drill stability
Grade Comparison Matrix
| Grade | Coating | Hardness | Best For |
|---|---|---|---|
| PR1535 ★ | TiAlN-TiSiN | 92.5 HRA | Steel, Stainless Steel, Cast Iron |
| PR1725 | AlCrN | 91.8 HRA | Hardened Steel (>50 HRC) |
| CA025P | TiAlN | 91.5 HRA | General Purpose, Aluminum |
| PR1215 | TiCN | 90.5 HRA | Non-Ferrous, Plastics |
Chipbreaker Profile
The DRILL 2FL TA series features a precision-ground parabolic flute form with polished rake faces (Ra 0.1 μm). This design architecture ensures:
- Superior chip evacuation in blind-hole and through-hole applications
- Reduced cutting forces by 15% compared to conventional 2-flute drills
- Stable chip curling radius preventing chip jamming in micro-diameter holes
- Polished margin lands minimizing friction and heat generation

| Blind-Hole Drilling | ✓ Good | Yes | Ensure adequate peck cycle for chip evacuation |
| Cross-Hole Drilling | △ Fair | With Care | Reduce feed by 30% at intersection |
| Inclined Entry | ✓ Good | Yes | Self-centering 140° point angle |
| Stacked Plate Drilling | ✓ Excellent | Yes | Consistent chip control across interfaces |
Recommended Cutting Conditions
| Material | Vc (m/min) | f (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Carbon Steel (C45) | 85 – 105 | 0.05 – 0.08 | 93,297 – 115,249 |
| Alloy Steel (4140) | 75 – 95 | 0.03 – 0.05 | 82,321 – 104,273 |
| Stainless Steel (304) | 65 – 80 | 0.04 – 0.06 | 71,345 – 87,809 |
| Cast Iron (GG25) | 105 – 125 | 0.07 – 0.10 | 115,249 – 137,202 |
| Aluminum (6061) | 165 – 205 | 0.10 – 0.15 | 181,106 – 225,011 |
Operating Guidelines
- Run-out Tolerance: Maintain TIR < 0.005 mm at the tool tip for optimal tool life and hole accuracy.
- Coolant: Use water-soluble coolant at 6–8% concentration. Minimum pressure 20 bar for internal coolant tools.
- Peck Cycle: For holes deeper than 2×D, employ peck drilling with 0.5×D peck depth and full retract to clear chips.
- Entry Surface: Ensure flat, perpendicular entry surface. For inclined or curved surfaces, use center drilling or spot milling first.
- Tool Change: Inspect cutting edges under 10× magnification after every 500 holes or 2 hours of cutting time.
- Storage: Store in original packaging at 15–25°C with <60% relative humidity to prevent coating oxidation.
