Grade Details — Key Grade Characteristics
The TA grade is a micro-grain tungsten carbide substrate featuring a proprietary multi-layer PVD coating architecture. This grade is specifically formulated for high-speed drilling operations where thermal cycling and abrasive wear are primary failure modes.
- Substrate Hardness: 1,650 HV (Vickers) — exceptional resistance to crater wear
- Transverse Rupture Strength: 3,800 MPa — optimized for interrupted cuts and cross-hole drilling
- Coating Composition: TiAlN-based multi-layer with enhanced oxidation resistance up to 900°C
- Coating Thickness: 3.5 ± 0.5 μm — balanced between adhesion and abrasion resistance
- Surface Finish: Mirror-polished flute surface (Ra 0.15 μm) for superior chip evacuation
- Edge Preparation: Micro-honed T-land (0.02 mm × 20°) for edge stability and burr reduction
Grade Comparison Matrix

| Chip Control | Excellent | Good | Good |
Chipbreaker Profile
The SGS51767 features an optimized flute geometry designed specifically for 3XD drilling applications. The flute profile incorporates a variable helix design with a polished surface treatment to minimize chip adhesion and packing.
| Profile Feature | Description |
|---|---|
| Flute Form | Parabolic flute with enhanced gash geometry for 2-flute chip division |
| Helix Angle | 30° constant helix for balanced cutting forces and hole straightness |
| Core Taper | Thickened core (0.35×D) for enhanced rigidity during 3× diameter penetration |
| Chipbreaker Type | Natural chip curl via flute geometry — no additional breaker grooves required |
| Surface Treatment | AlCrN-based low-friction coating on flute faces for easy chip flow |
Recommended Applications & Workpiece Materials
This drill is optimized for the following material groups and industrial sectors:
| Material Group | ISO Code | Performance Rating | Notes |
|---|---|---|---|
| Low-Carbon Steel | P1.1 – P1.3 | ★★★★★ | Excellent chip formation and tool life |
| Alloy Steel / Hardened Steel | P2.5 – P3.3 | ★★★★☆ | Reduce Vc by 15% for materials >45 HRC |
| Stainless Steel (Austenitic) | M1.0 – M2.1 | ★★★★☆ | Use high-pressure coolant to prevent work hardening |
| Cast Iron (Gray / Ductile) | K1.1 – K2.2 | ★★★★★ | Ideal for interrupted cuts and skin drilling |
| Aluminum Alloy (Wrought) | N1.3 – N3.2 | ★★★★☆ | Polished flute prevents built-up edge (BUE) |
| Titanium Alloy | S1.0 – S2.0 | ★★★☆☆ | Reduce feed by 20%; peck cycle recommended |
Application Map by Operation
| Operation Type | Suitability | Recommended Approach |
|---|---|---|
| Through-Hole Drilling | ✓ Excellent | Standard feed/speed; reduce feed 30% before breakthrough |
| Blind-Hole Drilling | ✓ Excellent | Peck cycle at 1×D intervals; dwell 1s at bottom |
| Stack Drilling | ✓ Good | Clamp plates rigidly; use pilot hole if stack >10 mm |
| Cross-Hole Intersection | △ Moderate | Reduce feed 40% at intersection; rigid setup mandatory |
| Inclined Entry / Exit | △ Moderate | Use spot drill first; reduce initial feed by 50% |
| Enlarging / Reaming | ✗ Not Recommended | Use dedicated reamer for tolerance < H7 |
Recommended Cutting Conditions
| Parameter | Starting Value | Range | Unit |
|---|---|---|---|
| Cutting Speed (Vc) | 110 | 120-160 | m/min |
| Feed per Revolution (fn) | 0.14 | 0.08-0.18 | mm/rev |
| Spindle Speed (n) | Calculated | 6,000-12,000 | rpm |
| Coolant Pressure | 70 | 50-100 | bar |
| Coolant Type | Emulsion (8-10%) | Emulsion / MQL / Oil | — |
| Peck Depth (for blind holes) | 1.0×D | 0.8–1.2×D | mm |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece material, and coolant delivery. For hardened steels (>45 HRC), reduce Vc by 20% and use peck cycle.
Operating Guidelines
- Spindle Requirements: High-speed spindle recommended. Minimum runout TIR ≤ 0.01 mm at tool tip.
- Toolholder: Use hydraulic or shrink-fit chuck (HSK-A63 or higher recommended). Collet holders acceptable only with < 0.01 mm runout.
- Coolant Strategy: Through-tool coolant or external flood coolant. Ensure coolant reaches the cutting edge without deflection.
- Peck Drilling: Mandatory for 3XD blind holes. Retract to 0.5×D above hole bottom to break chips.
- Entry Surface: Spot drill or mill a flat entry surface. Avoid drilling on cast/as-forged surfaces without preparation.
- Breakthrough: Reduce feed to 60% when remaining wall thickness < 0.5×D to prevent burr and exit breakout.
- Tool Life Monitoring: Replace when flank wear (VB) reaches 0.15 mm or when hole tolerance exceeds IT9.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | ✓ Preferred | Best damping and runout control for 3XD drilling |
| Shrink-Fit Chuck | ✓ Preferred | Excellent for high-speed applications >8,000 rpm |
| Precision Collet (ER25/ER32) | △ Acceptable | Verify collet runout < 0.01 mm; replace worn collets |
| Weldon Side-Lock | ✗ Not Recommended | Excessive runout for precision drilling; risk of chatter |
| Modular Drill Head | ✓ Compatible | Use only with rigid modular interface (e.g., Capto C6) |
