Grade Details - Key Grade Characteristics

The HP grade utilized in the KDZ0690X1.5S080N-HP represents Kyocera's premium high-precision coating technology. Key characteristics include:

  • Substrate: Ultra-fine grain tungsten carbide (0.8 μm) with 12% cobalt binder for optimal hardness-toughness balance
  • Coating: Multi-layer TiAlN PVD coating (3.5 μm total thickness) with nano-structured architecture
  • Hardness: 92.5 HRA providing excellent wear resistance at elevated cutting temperatures
  • Oxidation Resistance: Stable performance up to 900°C cutting temperature
  • Surface Finish: Mirror-polished rake face (Ra 0.05 μm) minimizes built-up edge and ensures chip flow consistency

  • Groove Width: 1.03 mm ±0.02 mm
  • Groove Depth: 0.55 mm with logarithmic curvature
  • Land Width: 0.83 mm honing for edge stability
  • Chip Control: Designed for short, manageable chip formation in hardened steel, tool steel, alloy steel
  • Back Taper: 0.02 mm over flute length to prevent binding

Recommended Applications & Workpiece Materials

The KDZ0690X1.5S080N-HP is optimized for the following material groups and application scenarios:

  • Primary Materials: hardened steel, tool steel, alloy steel
  • Secondary Materials: Titanium alloys (Ti-6Al-4V), Inconel 718, copper alloys
  • Industry Applications: Aerospace engine components, automotive transmission parts, hydraulic valve bodies, medical implant preforms
  • Hole Quality: IT8-IT9 tolerance capability, Ra 0.4-1.6 μm surface finish achievable

Application Map by Operation

Suitability ratings for common machining operations:

Operation TypeSuitabilityRecommended Use
Through-hole Drilling⭐⭐⭐⭐⭐ ExcellentPrimary application, optimal chip evacuation
Blind-hole Drilling⭐⭐⭐⭐☆ Very GoodEnsure proper peck cycle and coolant pressure
Counter-boring⭐⭐⭐☆☆ GoodReduce feed by 20% for best surface finish
Spot Drilling⭐⭐⭐⭐☆ Very GoodUse reduced speed for accurate starting
Enlarging⭐⭐⭐☆☆ GoodPre-drill with smaller diameter recommended

Recommended Cutting Conditions

Optimized parameters for the KDZ0690X1.5S080N-HP HP grade insert:

Workpiece MaterialCutting Speed Vc (m/min)Feed fn (mm/rev)Coolant
Carbon Steel (<30 HRC)60-1000.14-0.22Emulsion / MQL
Alloy Steel (30-45 HRC)50-900.14-0.22Emulsion
Stainless Steel (AISI 304/316)40-800.14-0.2High-pressure emulsion
Cast Iron (GG25/GGG40)70-1100.14-0.22Dry / Compressed air
Hardened Steel (45-55 HRC)30-700.11-0.17MQL / Oil mist

Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece fixturing, and coolant delivery efficiency. Reduce speeds by 15% for blind-hole applications.

Operating Guidelines

To maximize tool life and machining quality with the KDZ0690X1.5S080N-HP:

  • Ensure workpiece runout does not exceed 0.02 mm TIR at drilling depth
  • Use minimum coolant pressure of 10 bar for through-tool delivery; external flood coolant requires 8% concentration minimum
  • Peck drilling recommended for depths >3xD: retract to 1 mm above bottom every 5.5 mm of depth
  • Maintain consistent feed rate; avoid dwell at hole bottom to prevent work-hardening
  • Replace insert when flank wear (VB) reaches 0.15 mm or when surface finish degrades visibly
  • Store unused inserts in original packaging with desiccant; avoid direct sunlight and humidity >60% RH

Toolholder Compatibility

Verified compatible toolholder systems for the KDZ0690X1.5S080N-HP:
