| Aluminum alloys | N1.1 - N3.3 | Good | Aerospace, electronic enclosures |
Application Map by Operation
| Operation Type | Suitability | Conditions |
| Through-hole drilling | ★★★★★ | Dry or MQL (Minimum Quantity Lubrication) |
| Blind-hole drilling | ★★★★★ | Internal coolant recommended |
| Peck drilling | ★★★★☆ | 1.5xD peck depth for deep holes |
| Helical interpolation | ★★★☆☆ | Reduce feed by 30% |
| Stack drilling | ★★★★☆ | Use backing plate to prevent burr |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
| Low-alloy steel (< 700 N/mm²) | 80 - 120 | 0.10 - 0.18 | Emulsion / Dry |
| High-alloy steel (> 1000 N/mm²) | 50 - 80 | 0.08 - 0.14 | Internal coolant |
| Stainless steel (austenitic) | 40 - 70 | 0.08 - 0.12 | Internal coolant |
| Gray cast iron (HB 180-220) | 100 - 150 | 0.12 - 0.20 | Dry / Compressed air |
| Aluminum alloy (Si < 10%) | 150 - 250 | 0.15 - 0.25 | MQL / Dry |
Note: Start at the lower range for new applications and increase gradually based on tool life and surface finish requirements.
Operating Guidelines
- Runout: Maintain spindle runout below 0.01 mm TIR for optimal tool life and hole accuracy
- Coolant: Internal coolant (through-tool) is strongly recommended for holes deeper than 2xD; minimum pressure 20 bar
- Entry Angle: Use a chamfer or center drill to prevent walk-in on inclined surfaces; minimum 0.2 mm x 90° chamfer
- Exit Strategy: Reduce feed by 30% when breaking through to minimize burr formation
- Peck Cycle: For deep holes (> 3xD), use peck drilling with 1.5xD peck depth and full retract to clear chips
- Tool Presetting: Preset tool length to ±0.02 mm for consistent hole depth control
- Storage: Store in original packaging at room temperature; avoid contact with other tools to prevent edge chipping
