Grade Details - Key Grade Characteristics
TX is High-performance PVD-coated grade optimized for drilling operations. The substrate combines ultra-fine tungsten carbide grains (0.5 μm) with 12% cobalt binder, delivering the optimal balance of hardness and toughness for standard-depth drilling operations.
| Property | Value | Benefit |
|---|---|---|
| Coating Type | TiAlN-based multi-layer PVD coating | Superior heat resistance and low friction |
| Hardness | 92.0 HRA | Excellent wear resistance |
| Transverse Rupture Strength | 3,800 MPa | High resistance to chipping |
| Thermal Resistance | 900°C | Stable performance at high speeds |
| Coating Color | Copper-Bronze | Easy wear identification |
Grade Comparison Matrix
| Grade | Coating | Best For | Speed vs TX |
|---|---|---|---|
| TX | TiAlN PVD | Steel, Stainless, General Purpose | Baseline (100%) |
| PR1535 | TiAlN + TiSiN | Hardened Steel (>50 HRC) | +15% |
| PR1705 | AlCrN | High-Temp Alloys, Titanium | +10% |
| KW10 | Uncoated | Aluminum, Non-Ferrous | -20% (but sharper edge) |
Chipbreaker Profile
Standard 2-flute helical groove with optimized rake angle. The optimized flute geometry ensures efficient chip formation and evacuation, reducing the risk of chip packing and hole distortion during standard-depth drilling cycles.
- Helical flute design with polished rake surface for reduced friction
- Wide chip pocket volume for reliable chip flow
- Reinforced core design maintains rigidity under high thrust loads
- Polished flutes minimize built-up edge (BUE) on sticky materials
Recommended Applications & Workpiece Materials

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation with internal coolant |
| Blind-Hole Drilling | ★★★★☆ Very Good | Reduce feed 20% in last 2mm depth |
| Stack Drilling | ★★★☆☆ Good | Ensure rigid clamping; watch for vibration |
| Inclined Entry | ★★☆☆☆ Moderate | Use spotting drill first; max 5° incline |
| Cross-Hole Drilling | ★★☆☆☆ Moderate | Reduce feed to 60% when breaking through |
Recommended Cutting Conditions
Parameters are provided as starting recommendations. Adjust based on machine rigidity, coolant concentration, and specific workpiece material condition.
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Low-Carbon Steel (< 0.3% C) | 80 - 120 | 0.15 - 0.25 | 1,611 - 2,417 |
| Medium-Carbon Steel (0.3-0.6% C) | 72 - 108 | 0.14 - 0.23 | Refer to formula |
| Stainless Steel (Austenitic) | 56 - 84 | 0.12 - 0.20 | Refer to formula |
| Cast Iron (Gray) | 88 - 132 | 0.17 - 0.28 | Refer to formula |
Formula: RPM = (Vc × 1000) / (π × D). Always start at the lower end of the range and increase based on tool life and hole quality.
Operating Guidelines
- Coolant: Use water-miscible coolant at 8-10% concentration minimum. Ensure coolant pressure ≥ 20 bar for optimal chip evacuation through internal coolant channels.
- Pecking: For 5XD drills, peck depth should be 1.5×D to 2×D per peck in blind holes. Through-holes may use continuous feed with adequate coolant pressure.
- Entry Surface: Ensure perpendicular entry surface or use a spotting drill (90°-120°) to prevent walk-off and improve positional accuracy.
- Tool Runout: Maintain total indicated runout (TIR) below 0.01 mm at the tool tip. Excessive runout reduces tool life and hole quality.
- Chip Control: Monitor chip shape. Acceptable chips are C-shaped or short spirals. Long stringy chips indicate insufficient feed or coolant issues.
- Tool Life Check: Inspect flank wear after 50 holes. Maximum allowable flank wear (VBmax) is 0.3 mm for standard steel applications.
Toolholder Compatibility
Standard drill chucks (ER32, ER40), hydraulic holders, shrink fit holders
| Holder Type | Recommended For | Max Runout |
