| Transverse Rupture Strength | 3,200 MPa | High chipping resistance under intermittent loads |
| Coating Thickness | 2.5 µm | Balanced protection without edge rounding |
| Max Operating Temp | 960 °C | Suitable for dry and high-speed machining |
| Friction Coefficient | 0.16 | Reduced built-up edge and adhesion |
Grade Comparison Matrix
| Grade | Best For | Speed (vc) | Feed (fn) |
|---|---|---|---|
| PR1535 | Steel machining | 41-101 m/min | 0.06-0.31 mm/rev |
| PR1535 | General steel, stainless | 40-100 m/min | 0.05-0.25 mm/rev |
| CA6535 | Cast iron, heavy roughing | 60-120 m/min | 0.10-0.35 mm/rev |

| CA115 | Mild steel, continuous cut | 50-110 m/min | 0.08-0.30 mm/rev |
Chipbreaker Profile
The TX chipbreaker geometry is optimized for steel machining. It features a precisely ground rake face with a 10° positive rake angle and a 0.5 mm land width. This configuration promotes tightly curled chips that break predictably, preventing nest formation and protecting the finished hole wall.
- Chipbreaker Type: TX-style open groove
- Rake Angle: 10° positive
- Land Width: 0.5 mm
- Chip Curl Radius: 10 mm (typical)
- Chip Thickness Ratio: 1:4
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability | Notes |
|---|---|---|---|
| Steel | P20 | ★★★★★ Excellent | Primary target material |
| Stainless Steel | M20 | ★★★★☆ Very Good | Use reduced speed for austenitic grades |
| Cast Iron | K10 | ★★★★☆ Very Good | Excellent for gray and nodular cast iron |
| Aluminum | N20 | ★★★☆☆ Good | Polished flute recommended for sticky alloys |
| Hardened Steel | H20 | ★★★☆☆ Good | Up to 45 HRC with optimized parameters |
Application Map by Operation
| Operation | Suitability | Max Depth | Recommended coolant |
|---|---|---|---|
| Through-hole Drilling | ✓ Optimal | 12×D | External / Through-spindle |
| Blind-hole Drilling | ✓ Optimal | 10×D | External with chip evacuation |
| Peck Drilling | ✓ Recommended | 14×D | High-pressure through-spindle |
| Helical Interpolation | ✓ Possible | 6×D | External flood coolant |
| Counterboring | △ Caution | 1×D | External with reduced feed |
Recommended Cutting Conditions
Values are starting recommendations. Adjust based on machine rigidity, workpiece clamping, and coolant delivery.
| Material | vc (m/min) | fn (mm/rev) | Coolant |
|---|---|---|---|
| Steel | 41-101 | 0.06-0.31 | Emulsion 6-8% |
| Stainless Steel | 32-70 | 0.05-0.22 | Emulsion 8-10% / Oil |
| Cast Iron | 49-111 | 0.07-0.34 | Dry / Compressed air |
| Aluminum | 82-252 | 0.09-0.62 | Emulsion 5-6% / MQL |
| Hardened Steel | 20-40 | 0.03-0.12 | Oil / High-pressure emulsion |
Operating Guidelines
- Run-in Period: Reduce vc and fn by 20% for the first 10 holes to stabilize the cutting edge.
- Peck Cycle: For depths >3×D, use a peck depth of 1-1.5×D with full retract to break chips.
- Coolant Pressure: Maintain ≥20 bar (290 psi) for through-spindle coolant when drilling >5×D.
- Spindle Runout: Ensure TIR <0.01 mm at the tool point to prevent uneven wear.
- Tool Life Check: Monitor flank wear (VB). Regrind or replace when VB >0.3 mm for roughing or >0.15 mm for finishing.
- Storage: Store in original packaging away from humidity and direct sunlight. Avoid contact with other carbide tools to prevent edge chipping.
