Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ✓ Ideal | Full chip evacuation with internal coolant |
| Blind-Hole Drilling | ✓ Ideal | Precise depth control, reduced burr formation |
| Peck Drilling | ✓ Recommended | Use 1.5–2D peck depth for optimal chip breaking |
| Stack Drilling | △ Caution | Ensure rigid clamping and alignment |
| Micro-Drilling | ✗ Not Applicable | For diameters < 2.0 mm, use D88-Micro series |
| Trepanning | ✗ Not Recommended | Use dedicated trepanning tools |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed (fn) | RPM (n) |
|---|---|---|---|
| Carbon Steel | 91 m/min | 0.157 mm/rev | 5081 min⁻¹ |
| Alloy Steel | 77 m/min | 0.141 mm/rev | 4318 min⁻¹ |
| Stainless Steel | 63 m/min | 0.133 mm/rev | 3556 min⁻¹ |
| Cast Iron | 100 m/min | 0.173 mm/rev | 5589 min⁻¹ |
| Hardened Steel (50 HRC) | 45 m/min | 0.11 mm/rev | 2540 min⁻¹ |
| Titanium Alloy | 54 m/min | 0.126 mm/rev | 3048 min⁻¹ |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and hole depth. Use internal coolant pressure ≥ 20 bar for optimal performance.
Operating Guidelines
- Coolant: Use water-soluble coolant (8–10% concentration) or neat oil. Minimum internal coolant pressure: 20 bar (290 psi).
- Run-In: For first 10 holes, reduce Vc by 20% and fn by 15% to stabilize cutting edge.
- Peck Cycle: Recommended peck depth = 1.5–2.0 × D for depths > 3×D. Retract fully to clear chips.
- Entry Angle: Ensure perpendicular entry (±0.5°) or use spot drill (120°) to prevent walk-off.
- Exit Strategy: Reduce feed by 30% when breaking through to minimize burr formation.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB > 0.3 mm or when surface finish degrades.
- Storage: Store in original packaging at 15–25°C, humidity < 60%. Avoid contact with corrosive agents.
Toolholder Compatibility
| Holder Type | Compatible Model | Collet / Sleeve |
|---|---|---|
| Hydraulic Chuck | KTF-SD-057-H | Hydraulic Expansion (±0.003 mm) |
| ER Collet Chuck | KTF-SD-057-ER | ER57 (DIN 6499) |
| Shrink Fit Holder | KTF-SD-057-SF | H5 Interference Fit |
| Milling Chuck | KTF-SD-057-M | Wedge Clamping (±0.005 mm) |
Runout tolerance: < 0.005 mm at 3×D. Use balanced holders (G2.5 @ 20,000 rpm) for high-speed applications.
