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 7.00 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 34 7.00 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
K – Cast Iron GG25, GGG50, FC250 ★★★★☆ 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 3,637 0.12 Emulsion (8–10%)
Stainless Steel (304) 60 2,728 0.1 Emulsion + EP Additive
Aluminum (6061-T6) 120 5,456 0.18 Water-Soluble or Dry
Cast Iron (GG25) 64 2,909 0.132 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.
