Grade Details – Key Grade Characteristics
TA Grade is a high-performance micro-grain carbide substrate (WC grain size 0.5–0.8 μm) combined with a multi-layer TiAlN PVD coating (thickness ~3 μm). This grade offers:
- Exceptional hardness: HV 1,850 ± 100
- High hot hardness retention up to 900°C
- Low coefficient of friction (0.35 against steel)
- Superior oxidation resistance in wet and MQL cutting
- High transverse rupture strength (TRS ≥ 3,800 MPa)
Grade Comparison Matrix
| Grade | Coating | Best For | Speed Capability |
|---|---|---|---|
| TA | TiAlN PVD | Steel, Stainless Steel, Cast Iron | High |
| CA | TiCN + Al₂O₃ CVD | Heavy-duty roughing | Medium |
| DA | Diamond-like Carbon | Aluminum, Non-ferrous | Very High |
| PR | Uncoated Polished | Plastics, Composites | Low–Medium |
Chipbreaker Profile
The SGM07661 features an optimized double-margin flute design with a proprietary edge preparation ( honed at 0.02–0.03 mm) that promotes:
- Tight curl chip formation for reliable evacuation
- Reduced cutting forces by 15–20% compared to conventional 2-flute drills
- Stable drilling depth up to 3×D without pecking in steel
- Minimal burr formation at exit in through-hole applications
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Typical Use |
|---|---|---|---|
| Carbon & Alloy Steels | P.1 – P.5 | Excellent | General engineering, automotive |
| Stainless Steels (Austenitic) | M.1 – M.2 | Very Good | Medical, food processing |
| Cast Irons (Gray / Ductile) | K.1 – K.3 | Good | Pump housings, engine blocks |
| Aluminum Alloys | N.1 – N.3 | Good* | Aerospace, electronics |
| Titanium Alloys | S.1 – S.2 | Moderate | Aerospace fasteners |
*Use with air blast or MQL to prevent built-up edge in aluminum.
Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-hole Drilling | ★★★★★ | 5×D | Excellent chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 3×D | Use peck cycle beyond 2×D |
| Spot Drilling | ★★★★☆ | 0.5×D | Stable start, minimal wander |
| Chamfering | ★★★☆☆ | 0.2 mm | Light chamfer only |
| Engraving / Marking | ★★☆☆☆ | 0.1 mm | Not recommended |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 45 | 0.1 | Emulsion 5–8% |
| Stainless Steel (304) | 25 | 0.08 | Emulsion 8–10% |
| Aluminum (6061) | 90 | 0.15 | Air / MQL |
| Gray Cast Iron (GG25) | 40 | 0.12 | Dry / Air |
| Titanium (Ti-6Al-4V) | 20 | 0.07 | High-pressure coolant |
Operating Guidelines
- Speed & Feed: Start at the lower end of the recommended range for new setups; increase by 10% increments once stability is confirmed.
- Peck Drilling: For depths > 2×D, use a peck cycle with 0.5×D peck depth and full retract to break chips.
- Coolant: Ensure adequate coolant flow (pressure ≥ 20 bar for high-speed steel; ≥ 40 bar for titanium). Avoid interrupted coolant flow.
- Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB reaches 0.15 mm or when burr size increases noticeably.
- Runout: Keep total indicated runout (TIR) below 0.01 mm at the tool tip for optimal hole quality and tool life.
Toolholder Compatibility
| Holder Type | Compatibility | Recommended Taper |
