- Coating: Multi-layer TiAlN-based PVD coating with optimized adhesion and thermal stability up to 900°C
- Hardness: 92 HRA — exceptional wear resistance for abrasive materials
- Transverse Rupture Strength: 211600 N/mm² — superior resistance to chipping and breakage
- Oxidation Resistance: Excellent thermal stability for dry and MQL machining
- Friction Coefficient: Reduced friction for lower cutting temperatures and extended tool life

Chipbreaker Profile
The SGS69167 features an optimized flute and point geometry designed for superior chip formation and evacuation:
- Flute Profile: Parabolic flute design with polished surfaces (Ra ≤0.4 µm) to minimize chip adhesion and friction
- Chipbreaker Geometry: Precision-ground margins with controlled land width for stable chip curling and breakage
- Point Geometry: Self-centering 140° point with thinned web for reduced thrust forces and improved penetration
- Edge Preparation: Honored cutting edges (T-land micro-geometry) for enhanced edge stability and reduced burr formation
- Chip Evacuation: Wide, polished flutes accommodate high feed rates while preventing chip packing in deep holes
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability | Notes |
|---|---|---|---|
| Carbon Steel (≤0.5% C) | P.1 – P.2 | ★★★★★ Excellent | High speed, long tool life |
| Alloy Steel / Hardened Steel | P.3 – P.5 | ★★★★★ Excellent | Up to 45 HRC with reduced Vc |
| Stainless Steel (Austenitic) | M.1 – M.2 | ★★★★★ Excellent | Optimized for work-hardening resistance |
| Stainless Steel (Martensitic) | M.3 | ★★★★☆ Very Good | Use moderate feeds |
| Cast Iron (Gray / Ductile) | K.1 – K.2 | ★★★★☆ Very Good | Dry machining recommended |
| Aluminum Alloys | N.1 – N.3 | ★★★★☆ Very Good | High speed, polished flutes prevent built-up edge |
| Titanium Alloys | S.1 – S.2 | ★★★☆☆ Good | Reduce Vc by 30%, use MQL |
| High-Temp Alloys (Inconel) | S.3 – S.4 | ★★★☆☆ Good | Low speed, high feed strategy |
Application Map by Operation
| Operation Type | Suitability | Guidelines |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Standard application; use recommended parameters. Peck cycle optional for L/D > 2.5 |
| Blind-Hole Drilling | ★★★★★ | Ensure adequate chip evacuation; reduce feed by 10% in final 2mm |
| Deep-Hole Drilling (3×D–5×D) | ★★★★☆ | Implement peck drilling cycle (Q = 1×D–1.5×D); use high-pressure coolant |
| Stack Drilling | ★★★★☆ | Excellent for thin plates; use rigid setup and clamping |
| Cross-Hole Drilling | ★★★☆☆ | Reduce feed by 20% when exiting into cross-hole; use center drill pre-hole |
| Enlarging / Sizing | ★★★☆☆ | Possible with reduced depth of cut; not recommended as primary application |
Recommended Cutting Conditions
The following parameters are recommended for stable, high-productivity machining. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (P.1–P.2) | 95 – 115 | 0.159 – 0.209 | Emulsion / MQL |
| Alloy Steel (P.3–P.5) | 80 – 95 | 0.139 – 0.159 | Emulsion / MQL |
| Stainless Steel (M.1–M.2) | 72 – 87 | 0.131 – 0.171 | High-pressure emulsion |
| Cast Iron (K.1–K.2) | 85 – 105 | 0.159 – 0.219 | Dry / Compressed air |
| Aluminum (N.1–N.3) | 143 – 173 | 0.226 – 0.306 | Emulsion / MQL |
| Titanium (S.1–S.2) | 52 – 72 | 0.111 – 0.131 | High-pressure emulsion |
Note: For 7,7mm diameter, spindle speed (n) ≈ 3927–4753 RPM for carbon steel at Vc = 95–115 m/min.
Operating Guidelines
- Pre-Drilling: For holes deeper than 2.5×D or when drilling into inclined surfaces, use a center drill or spotting drill to create a 90°–118° pilot hole
- Peck Cycle: Implement peck drilling for L/D > 2.5. Recommended peck depth: 1×D to 1.5×D with full retract to break chips
- Coolant Pressure: Minimum 20 bar (300 PSI) for through-tool coolant; 70 bar (1000 PSI) recommended for deep-hole and stainless steel applications
- Runout Tolerance: Keep total indicated runout (TIR) below 0.02mm at the tool tip for optimal tool life and hole quality
- Feed Rate: Never reduce feed below 0.08 mm/rev to avoid rubbing and work-hardening, especially in stainless steels
- Entry Angle: When drilling into curved or angled surfaces, reduce feed by 30% during entry or use a pilot hole
- Tool Change: Inspect cutting edges after every 50 holes; replace when flank wear exceeds 0.15mm or when burr formation increases
Toolholder Compatibility
| Holder Type | Shank Diameter | Compatibility |
|---|---|---|
| Hydraulic Chuck (Standard) | 7.9mm | ★★★★★ Excellent damping, best for general use |
| Shrink Fit Holder | 7.9mm | ★★★★★ Maximum rigidity and runout accuracy |
| Collet Chuck (ER25/ER32) | 7.9mm | ★★★★☆ Good for standard applications; ensure proper torque |
| Milling Chuck (Power Chuck) | 7.9mm | ★★★★☆ High clamping force, suitable for heavy cuts |
| Weldon Flat Holder | 7.9mm | ★★★☆☆ Possible with set screw; check for runout |
Recommended toolholder: Hydraulic chuck or shrink-fit holder with H4 bore for best performance and tool life.
