Grade Details - Key Grade Characteristics
CA6535 is a high-performance PVD-coated fine-grain carbide grade specifically developed for solid carbide drilling applications in the 13.00 mm diameter range. The substrate combines a cobalt-enriched tungsten carbide matrix with a multi-layer TiAlN+TiSiN coating stack, delivering:
- Hardness: 1,650 HV ( substrate ) / 3,200 HV ( coating )
- Transverse Rupture Strength: 4,200 MPa
- Oxidation Resistance: Up to 900°C continuous operating temperature
- Coating Thickness: 2.5 ± 0.3 μm
- Friction Coefficient: 0.35 (dry machining against AISI 1045)
- Edge Preparation: Micro-honed T-land (0.05 mm × 20°)
Grade Comparison Matrix
| Grade | Coating | Primary Material | Max Speed (m/min) | Wear Resistance | Best For |
|---|---|---|---|---|---|
| CA6535 | TiAlN+TiSiN | Steel, Stainless Steel | 80–120 | ★★★★★ | High-speed continuous drilling |
| PR1535 | TiAlN | Steel, Cast Iron | 60–90 | ★★★★☆ | General-purpose machining |
| CA5100 | AlCrN | Hardened Steel (>45 HRC) | 40–60 | ★★★★★ | Hard material drilling |
Chipbreaker Profile
The D88 13.00 mm drill incorporates a proprietary double-margin chipbreaker geometry with polished flute surfaces (Ra 0.2 μm). The chipbreaker features:
- Primary Rake Angle: 12° (positive) for reduced cutting forces
- Secondary Land Width: 0.08 mm at 25° for edge reinforcement
- Margin Width: 0.15 mm per flute for hole-wall burnishing
- Chipbreaker Depth: 0.04 mm with sinusoidal groove pattern
- Flute Polishing: Mirror-finish flute grinding to prevent built-up edge (BUE)
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability | Recommended? |
|---|---|---|---|
| P – Steel | AISI 1045, 4140, 4340, SS400 | ★★★★★ | Excellent |
| M – Stainless Steel | 304, 316, 17-4PH, 420 | ★★★★☆ | Good |

| N – Non-Ferrous | Al 6061, Al 7075, Brass | ★★★★★ | Excellent |
| S – Super Alloys | Inconel 718, Ti-6Al-4V | ★★★☆☆ | Moderate (reduce speed 30%) |
Application Map by Operation
| Operation Type | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 3×D | Standard application; excellent chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | 2.5×D | Reduce feed 20% in final 1×D depth |
| Stack Drilling | ★★★★☆ | Variable | Use peck cycle for plates >10 mm |
| Cross-Hole Intersection | ★★★☆☆ | — | Reduce feed 40% at intersection point |
| Inclined Entry | ★★★☆☆ | — | Max 15° inclination without pilot hole |
Recommended Cutting Conditions
| Workpiece Material | Vc (m/min) | RPM | Feed (mm/rev) | Coolant |
|---|---|---|---|---|
| Carbon Steel (AISI 1045) | 80 | 1,958 | 0.15 | Emulsion (8–10%) |
| Stainless Steel (304) | 60 | 1,469 | 0.12 | Emulsion + EP Additive |
| Aluminum (6061-T6) | 120 | 2,938 | 0.2 | Water-Soluble or Dry |
| Cast Iron (GG25) | 64 | 1,566 | 0.165 | Dry or Minimum Quantity |
Values are starting recommendations. Optimize based on machine rigidity, workpiece fixturing, and coolant delivery pressure (minimum 20 bar recommended for through-tool coolant).
Operating Guidelines
- Runout Tolerance: Maintain TIR ≤ 0.01 mm at the tool tip. Excessive runout accelerates corner wear and compromises hole tolerance.
- Coolant Pressure: For through-tool coolant applications, maintain 20–70 bar pressure. External flood coolant is acceptable for shallow holes (<1.5×D).
- Peck Cycle: Recommended for blind holes deeper than 2×D. Peck increment = 0.5×D with full retract to break chips.
- Entry Angle: For inclined or curved surfaces, use a pilot hole or reduce feed by 50% for the first 0.5×D to prevent walk.
- Tool Life Monitoring: Replace or regrind when flank wear (VB) exceeds 0.15 mm or when burr formation at hole exit increases significantly.
- Re-sharpening: Maximum 2 regrinds recommended. Regrind only the point geometry; do not alter the flute profile.
