Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 3×D | Optimal chip evacuation with through-coolant |
| Blind-Hole Drilling | ★★★★☆ | 2×D | Use peck cycle recommended; avoid full-width engagement at bottom |
| Micro-Drilling | ★★★★★ | 2×D | ≤ 3 mm diameter specialist; rigid setup mandatory |
| Enlarging / Reaming | ★★☆☆☆ | 1×D | Not recommended as primary use; dedicated reamer preferred |
| Spot Drilling | ★★★★☆ | 0.5×D | Use rigid setup; centre drill preferred for deep holes |
| Cross-Hole Drilling | ★★★☆☆ | 1×D | Reduce feed by 30%; expect reduced tool life |
| Inclined Entry | ★★☆☆☆ | 1×D | Requires spot drill or centre drill pre-operation |
Recommended Cutting Conditions
| Workpiece Material | Hardness | Cutting Speed (vc) | Feed per Rev (fn) | Coolant |
|---|---|---|---|---|
| Low-Carbon Steel | < 200 HB | 57-86 m/min | 0.08-0.12 mm/rev | Emulsion / MQL |
| Medium-Carbon Steel | 200-280 HB | 50-72 m/min | 0.06-0.10 mm/rev | Emulsion / MQL |
| Alloy Steel | 280-350 HB | 40-60 m/min | 0.05-0.08 mm/rev | Emulsion / Internal |
| Stainless Steel (Austenitic) | < 250 HB | 30-50 m/min | 0.04-0.07 mm/rev | Internal coolant essential |
| Gray Cast Iron | 180-260 HB | 40-60 m/min | 0.08-0.14 mm/rev | Dry / Compressed air |
| Aluminum Alloy (Wrought) | < 100 HB | 80-120 m/min | 0.10-0.18 mm/rev | MQL / Air blast |
| Titanium Alloy | 300-380 HB | 15-25 m/min | 0.03-0.05 mm/rev | High-pressure internal coolant |
Operating Guidelines
| Guideline | Recommendation |
|---|---|
| Runout Control | Maintain tool runout ≤ 0.01 mm at the tool tip. Use precision collets (ER16 or better) and verify spindle runout before operation. |
| Peck Drilling | For depths > 2×D, implement peck cycles with retract depth of 0.5×D to ensure chip breaking and evacuation. |
| Coolant Strategy | Internal coolant (through-tool) at 20-40 bar pressure is strongly recommended for holes > 1.5×D. For external coolant, use high-volume flood delivery. |
| Entry Angle | Ensure perpendicular entry (90° ± 1°) or use a spot drill/centre drill to prevent walk and chipping on entry. |
| Speed Ramp | Reduce cutting speed by 20% for the first 10 holes to condition the cutting edge (break-in period). |
| Chip Inspection | Monitor chip formation. Ideal chips should be short comma-shaped or C-shaped. Long stringy chips indicate insufficient feed or worn edges. |
| Tool Life Monitoring | Replace drill when flank wear (VB) reaches 0.15 mm or when hole tolerance exceeds h8. Do not attempt re-sharpening. |
| Workpiece Fixturing | Ensure rigid workpiece clamping. Minimum fixture mass should be 10× tool mass to suppress vibration. |
Toolholder Compatibility
| Holder Type | Specification | Compatibility |
|---|---|---|
| Precision Collet Chuck | ER16, ER20 (≤ 3.0 mm collet) | ★★★★★ Recommended |
| Hydraulic Chuck | HSK-E40, HSK-E50, BT30 | ★★★★★ Premium Option |
| Shrink Fit Holder | 3.0 mm bore, HSK-E40 | ★★★★☆ High rigidity |
| Drill Chuck | Keyless precision (0.5-4 mm) | ★★★☆☆ Acceptable for short holes only |
| Modular Tool System | Kyocera MEV / MEX series | ★★★★☆ Direct integration |
