Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Ideal for 5×D depth with coolant |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle for chips >2×D |
| Stack Drilling | ★★★★☆ | Excellent positional accuracy |
| Cross-Hole Drilling | ★★★☆☆ | Reduce feed to 70% at intersection |
| Inclined Entry | ★★★☆☆ | Use spot drill first if angle >5° |
Recommended Cutting Conditions
| Parameter | Range | Optimal Start |
|---|---|---|
| Cutting Speed (Vc) | 80 - 180 m/min | Mid-range, adjust per material |
| Feed per Revolution (fn) | 0.10 - 0.25 mm/rev | 0.15 × D mm/rev |
| Axial Depth (ap) | 1.0 - 3.0 × D | 2.5 × D for stable conditions |
| Coolant Pressure | 20 - 70 bar (internal) | 40 bar for 5×D applications |
| Coolant Type | Emulsion (5-10%) or neat oil for steel | |
Operating Guidelines
- Run-in Period: Reduce Vc by 20% and fn by 15% for the first 50 holes to stabilize cutting edges.
- Tool Life Monitoring: Monitor flank wear (VB). Resharpen or replace when VB exceeds 0.3 mm for precision applications.
- Hole Quality: For IT8-IT9 tolerance holes, maintain rigid toolholding and minimize overhang. Use hydraulic chucks or shrink-fit holders.
- Chip Control: If chips are not breaking satisfactorily, increase feed by 10% or verify coolant concentration and pressure.
- Storage: Store in original packaging at 15-25°C, humidity <60%. Avoid contact with corrosive agents.
Toolholder Compatibility
| Holder Type | Compatibility | TIR Requirement |
|---|---|---|
| Hydraulic Chuck (e.g., HSK-A63) | ★★★★★ | ≤ 3 μm |
| Shrink-Fit Holder | ★★★★★ | ≤ 3 μm |
| Precision Collet (ER16-ER32) | ★★★★☆ | ≤ 5 μm |
| Weldon Side-Lock | ★★★☆☆ | ≤ 10 μm |
Note: For 12.0 mm shank, use corresponding collet/holder size. Ensure through-tool coolant capability for deep-hole applications.
