- Core Thickness: 22% of nominal diameter for optimal rigidity
- Chipbreaker Width: 0.08 × D1
- Chipbreaker Depth: 0.03 × D1
- Land Width: 0.12 × D1 with honed T-land (0.02 mm)
- Margin: Narrow primary margin + secondary relief for reduced friction
7. Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability | Notes |
|---|---|---|---|
| Low-Carbon Steel (< 0.3% C) | P1.1–P1.2 | ★★★★★ | Excellent chip control; high-speed capable |
| Medium-Carbon Steel (0.3–0.6% C) | P2.1–P2.5 | ★★★★★ | Balanced wear and toughness performance |
| High-Carbon Steel / Alloy Steel | P3.0–P4.0 | ★★★★☆ | Reduce Vc by 15% for optimal life |
| Austenitic Stainless Steel | M1.0–M2.0 | ★★★★☆ | Use peck cycle; ensure coolant delivery |
| Cast Iron (Gray / Ductile) | K1.0–K3.0 | ★★★☆☆ | Dry or MQL recommended; watch for abrasion |
| Aluminum Wrought Alloys | N1.0–N3.0 | ★★★★☆ | Polished flutes prevent built-up edge |
| Titanium Alloys | S1.0–S4.0 | ★★★☆☆ | Low Vc, high feed; rigid setup mandatory |
8. Application Map by Operation
| Operation | Capability | Recommended Depth | Hole Quality |
|---|---|---|---|
| Through-Hole Drilling | ✓ Primary | Up to 3×D | IT8–IT9, Ra 0.8–1.6 μm |
| Blind-Hole Drilling | ✓ Excellent | Up to 2.5×D | IT9, Ra 1.6 μm |
| Spot Drilling / Chamfering | ✓ Capable | 0.2–0.5×D | — |
| Stack Plate Drilling | ✓ Good | Per plate thickness | IT9–IT10 |
| Cross-Hole Intersection | △ Caution | Reduce feed 30% | IT10 |
9. Recommended Cutting Conditions
| Workpiece Material | Vc (m/min) | Feed fn (mm/rev) | RPM (approx.) | Coolant |
|---|---|---|---|---|
| Low-Alloy Steel (< 900 MPa) | 90 | 0.168 | 3799 | Emulsion (8–10%) |
| Stainless Steel (AISI 304/316) | 77 | 0.129 | 3250 | Emulsion (10–12%) |
| Aluminum Alloy (6061-T6) | 168 | 0.2 | 7092 | Air / MQL |
| Cast Iron (GG25) | 62 | 0.185 | 2659 | Dry or Air |
| Titanium (Ti-6Al-4V) | 46 | 0.116 | 1950 | High-Pressure (70 bar) |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant pressure, and hole depth. For depths > 2.5×D, reduce feed by 15–20% and employ peck drilling.
10. Operating Guidelines
- Runout Tolerance: Keep total indicated runout (TIR) below 0.01 mm at the tool tip. Excessive runout accelerates corner wear and degrades hole straightness.
- Coolant Delivery: For internal coolant tools, maintain minimum pressure of 20 bar. For external coolant, use directed nozzles targeting the cutting zone.
- Peck Cycle: Recommended for blind holes > 2×D. First peck = 1.5×D, subsequent pecks = 0.5–0.7×D. Retract to break chip fully.
- Entry Angle: When drilling inclined surfaces, use a spot drill or center drill first to create a 90° entry surface. Minimum entry angle tolerance is ±5° without spot drilling.
- Tool Life Indicator: Monitor flank wear (VB). Replace or regrind when VB reaches 0.15 mm for precision work or 0.25 mm for general machining.
- Storage: Store in original packaging away from humidity. Avoid contact between cutting edges to prevent chipping.
11. Toolholder Compatibility
| Holder Type | Compatibility | Runout Capability | Best Use Case |
|---|---|---|---|
| Hydraulic Chuck (HSK-A63) | ★★★★★ | < 0.003 mm | High-precision finishing |
| Shrink Fit Chuck | ★★★★★ | < 0.003 mm | High-speed / HSM |
| Precision Collet (ER25/ER32) | ★★★★☆ | 0.005–0.010 mm | General purpose |
| Milling Chuck (MA) | ★★★☆☆ | 0.010–0.020 mm | Roughing / heavy stock removal |
| Drill Chuck (Keyed / Keyless) | ★★☆☆☆ | 0.020–0.050 mm | Manual / low-precision only |
