8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation with internal coolant |
| Blind-Hole Drilling | ★★★★★ Excellent | Precise depth control, minimal burr formation |
| Stack Drilling | ★★★★☆ Very Good | Use reduced feed at interface |
| Cross-Hole Drilling | ★★★★☆ Very Good | Reduce speed by 15% at intersection |
| Inclined Entry | ★★★☆☆ Good | Use spot drill or reduced feed for first 1×D |
9. Recommended Cutting Conditions
| Material Group | Cutting Speed Vc (m/min) | Feed fn (mm/rev) |
|---|---|---|
| Carbon Steel (≤ 800 N/mm²) | 60 – 100 | 0.12 – 0.20 |
| Alloy Steel (800–1200 N/mm²) | 51 – 85 | 0.11 – 0.18 |
| Stainless Steel (Austenitic) | 45 – 75 | 0.12 – 0.20 |
| Cast Iron (GGL/GGG) | 66 – 110 | 0.13 – 0.22 |
| Hardened Steel (45–55 HRC) | 36 – 60 | 0.10 – 0.16 |
10. Operating Guidelines
- Coolant Pressure: Minimum 20 bar (290 psi) internal coolant for optimal chip evacuation at 8×D depth.
- Coolant Type: Water-miscible cutting fluid (8–10% concentration) or neat oil for titanium/inconel.
- Pecking: Not required for depths ≤ 8×D when adequate coolant pressure is maintained. For interrupted cuts, use 2×D peck depth.
- Entry Angle: For inclined or curved surfaces, reduce feed to 50% for the first 1×D, or use a spot drill.
- Exit Strategy: Reduce feed by 30% in the last 2 mm to prevent burr formation and breakthrough damage.
- Tool Life Indicator: Monitor flank wear (VB). Regrind or replace when VB = 0.15 mm or when surface finish degrades.
11. Toolholder Compatibility
| Holder Type | Compatibility | Recommended Taper |
|---|---|---|
| Hydraulic Chuck | ★★★★★ Excellent | HSK-A63, BT40 |
| Shrink Fit | ★★★★★ Excellent | HSK-A63, BT40 |
| Precision Collet (ER) | ★★★★☆ Very Good | ER16, ER20 (≤ 0.01 mm runout) |
| Milling Chuck | ★★★★☆ Very Good | Any standard CNC taper |
Runout Requirement: Maximum total indicated runout (TIR) ≤ 0.01 mm at 3×D for optimal performance and tool life.
