Grade Details - Key Grade Characteristics

Uncoated Grade — This drill utilizes a uncoated micro-grain carbide substrate engineered for optimal balance between hardness and toughness. The substrate features:

  • Grain Size: 1.0 μm micro-grain structure for superior edge retention
  • Coating: Uncoated with 3-layer architecture for heat resistance and reduced friction
  • Hardness: 92.5 HRA for extended wear resistance
  • Transverse Rupture Strength: 3,200 N/mm² for impact resistance
  • Application Range: Ideal for high-speed drilling operations

Chipbreaker Profile

The D90 series features an optimized flute and point geometry designed for superior chip formation and evacuation:

  • Flute Profile: Parabolic flute design with polished surface (Ra 0.3 μm) to minimize chip adhesion
  • Chipbreaker Geometry: Continuous helical chip groove with narrow land width for controlled chip curling
  • Margin Design: Single margin with 0.15 mm width for hole wall stability and reduced friction
  • Point Configuration: Thinned web with web thinning for reduced thrust force and improved centering
  • Coolant Channels: External coolant design for effective heat dissipation

High-Speed Drilling★★★★☆Vc 120-200 m/min, rigid setup required
Deep Hole Drilling (>5×D)★★★☆☆Step drilling or specialized deep-hole cycle

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and hole depth requirements. For holes >3×D, reduce feed by 15-25%.

Operating Guidelines

  • Runout Tolerance: Maximum tool runout should not exceed 0.02 mm at the cutting edge to prevent uneven wear and hole enlargement
  • Peck Drilling: For holes deeper than 3×D, use a peck cycle with retract to break chips and allow coolant penetration
  • Coolant Pressure: Minimum 15 bar recommended for through-coolant tools; ensure adequate flow rate for heat removal
  • Tool Life Monitoring: Monitor flank wear (VB max = 0.3 mm) and replace before degradation affects hole quality
  • Entry/Exit: Use chamfer or center drill for entry; reduce feed by 50% for exit to prevent burr formation
  • Storage: Store in original packaging away from moisture and corrosive environments to preserve coating integrity
