Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimized point geometry prevents burr formation |
| Blind-Hole Drilling | ★★★★★ Excellent | 3-flute design ensures efficient chip evacuation |
| Peck Drilling | ★★★★☆ Very Good | Recommended for holes >3×D depth |
| Stack Drilling | ★★★★☆ Very Good | Use reduced feed for entry/exit control |
| Cross-Hole Drilling | ★★★☆☆ Good | Reduce speed by 20% at intersection |
| Enlarging / Reaming | ★★☆☆☆ Fair | Not recommended; use dedicated reamer |
Recommended Cutting Conditions
Parameters below are starting recommendations for external coolant (emulsion 6–8%). Adjust based on machine rigidity and setup:
| Parameter | Carbon Steel | Alloy Steel | Stainless Steel | Cast Iron |
|---|---|---|---|---|
| Cutting Speed (Vc) | 130 – 170 m/min | 110–144 m/min | 91–118 m/min | 143–187 m/min |
| Spindle Speed (n) | 2,500 – 4,000 min⁻¹ | Reduce 15% | Reduce 30% | Increase 10% |
| Feed per Rev (fn) | 0.25 – 0.40 mm/rev | 0.25 – 0.40 mm/rev | 0.20–0.32 mm/rev | 0.29–0.46 mm/rev |
| Axial Depth (ap) | 2D – 5D | 2D – 5D | 1.5D–2.5D | 2D – 5D |
| Coolant | External / Internal (if available) | External emulsion 6–8% | External emulsion 8–10% | Dry or compressed air |
Operating Guidelines
- Run-in Period: For the first 5 holes, reduce cutting speed by 20% and feed by 10% to stabilize the cutting edge.
- Peck Cycle: For holes exceeding 3×D, use a peck depth of 1.5–2.0×D with full retract to clear chips and allow coolant penetration.
- Entry Angle: Ensure the workpiece surface is perpendicular to the drill axis; use a spot drill (90°–120°) for inclined entries >3°.
- Coolant Pressure: Maintain minimum 20 bar (290 psi) for through-spindle coolant applications; 5–10 bar for external flood coolant.
- Tool Life Check: Monitor flank wear (VB). Regrind or replace when VB exceeds 0.15 mm for precision applications or 0.25 mm for general machining.
- Storage: Store in original packaging at 15–25°C with <60% relative humidity. Avoid contact with corrosive agents.
Toolholder Compatibility
For optimal performance and runout accuracy (<0.01 mm TIR), use the following toolholder systems:
- Recommended: BT50, HSK-A100, CAT50 hydraulic chucks, shrink-fit holders
- Runout Requirement: ≤0.01 mm at 3×D projection
- Clamping Method: Hydraulic or shrink-fit (preferred); precision ER collet (minimum ER25 for 17.5 mm)
- Spindle Interface: HSK-A63 or higher recommended for high-speed applications
