Chipbreaker Profile
The 8.2 mm drill features an optimized 2-flute chipbreaker geometry designed for efficient chip evacuation in deep-hole drilling (5×D). The flute profile incorporates a parabolic gash with polished rake surfaces to minimize chip adhesion and reduce built-up edge formation. Key chipbreaker parameters:
- Rake angle (γ): 12° – 15° (positive)
- Flute depth: 2.87 mm
- Chipbreaker width: 1.23 mm
- Surface finish: Mirror-polished (Ra ≤ 0.2 μm)
- Coolant channel: Through-tool coolant ready (optional)
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommended? |
|---|---|---|---|
| Carbon Steel (< 300 HB) | P1.1 – P2.5 | Excellent | ✓ Primary |
| Alloy Steel (300–400 HB) | P3.0 – P4.0 | Very Good | ✓ Primary |
| Stainless Steel (Austenitic) | M1.0 – M2.0 | Good | ✓ Recommended |
| Cast Iron (Grey / Nodular) | K1.0 – K3.0 | Good | ✓ Recommended |
| Aluminium & Alloys | N1.0 – N3.0 | Excellent | ✓ Recommended |
| Hardened Steel (> 45 HRC) | H1.0 – H2.0 | Moderate | △ Conditional |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Optimal chip evacuation; use peck cycle for L/D > 3 |
| Blind-hole Drilling | ★★★★☆ | Reduce feed by 20% in last 1×D; ensure adequate coolant |
| Stack Drilling | ★★★☆☆ | Clamp workpiece firmly; watch for burr formation at interface |
| Cross-hole Drilling | ★★☆☆☆ | Reduce speed 30%; use rigid toolholding (hydraulic or shrink fit) |
| Enlarging / Reaming | ★☆☆☆☆ | Not recommended; use dedicated reamer for finishing |
Recommended Cutting Conditions
| Parameter | Value / Range | Notes |
|---|---|---|
| Cutting Speed (Vc) | 60 – 100 m/min | Start at lower end; increase if chip color is silver/blue |
| Feed per Revolution (fn) | 0.10 – 0.20 mm/rev | Higher feed improves chip breaking; lower feed improves surface finish |
| Spindle Speed (n) | 4,000 – 8,000 min-1 | Depends on machine capability and workpiece rigidity |
| Coolant Pressure | 20 – 70 bar (internal) | Internal coolant strongly recommended for 5×D drilling |
| Coolant Type | Emulsion (6–8%) or MQL | Use high-lubricity coolant for stainless and titanium |
Operating Guidelines
- Peck Drilling Cycle: For holes deeper than 3×D, use a peck cycle with retract of 0.5–1×D to break chips and allow coolant penetration.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent corner chipping. Use a spot drill or centre drill for precise starting.
- Tool Overhang: Minimize tool overhang to 4×D or less. Use hydraulic or shrink-fit holders for best rigidity.
- Corner Preparation: If drilling into a curved or angled surface, chamfer or spot-face the entry to avoid uneven loading.
- Chip Inspection: Monitor chip shape. Ideal chips are short, C-shaped, or 6-9 shaped. Long stringy chips indicate insufficient feed or worn edges.
- Tool Life Monitoring: Replace tool when flank wear (VB) reaches 0.2 mm or when burr formation on hole exit increases significantly.
Toolholder Compatibility
| Holder Type | Compatibility | Recommended For |
|---|---|---|
| Hydraulic Chuck (Hydro) | ✓ Excellent | High-precision finishing, tight tolerances |
| Shrink Fit | ✓ Excellent | High-speed machining, minimal runout |
| Collet Chuck (ER32/ER40) | ✓ Good | General-purpose machining, good versatility |
| Weldon Side-Lock | △ Fair | Heavy roughing only; may induce runout > 10 μm |
| Modular Tooling (HSK-T) | ✓ Excellent | CNC turning centres with driven tooling |
