Grade Details – Key Grade Characteristics

The PR930 grade utilized in this drill body features a high-transverse-rupture-strength (TRS) carbide substrate combined with a multi-layer PVD coating. This combination provides:

  • Superior adhesion resistance for uninterrupted chip flow
  • Enhanced thermal stability for dry and near-dry machining
  • Optimized micro-geometry for reduced cutting forces and improved hole entry
  • High flank wear resistance maintaining hole tolerance over extended cutting periods

Chipbreaker Profile

The KDA series incorporates a proprietary GM (General Machining) chipbreaker geometry optimized for 4.40 mm drilling operations. The chipbreaker features a dual-rake design with a positive primary rake angle of 12° and a secondary land of 0.15 mm width, ensuring:

  • Controlled chip curling and segmentation for reliable evacuation
  • Reduced built-up edge (BUE) formation on ductile materials
  • Stable cutting edge temperature distribution
  • Compatibility with through-tool coolant pressure up to 70 bar

Recommended Applications & Workpiece Materials

The KDA0440X03S060C is ideally suited for the following material groups and application scenarios:

  • Carbon & Alloy Steels (P-Group): Up to 1200 N/mm² tensile strength
  • Stainless Steels (M-Group): Austenitic and duplex grades (304, 316, 2205)
  • Cast Irons (K-Group): Grey cast iron (GG25) and nodular iron (GGG50)
  • Non-Ferrous Metals (N-Group): Aluminum alloys up to 12% Si content
  • Superalloys (S-Group): Limited application with reduced speeds

Application Map by Operation

Suitability ratings for common drilling operations:

Operation Suitability Recommended Conditions

Recommended Cutting Conditions

Starting parameters for stable machining. Adjust based on machine rigidity and setup:

Workpiece Material Cutting Speed Vc (m/min) Feed fn (mm/rev) Coolant
Carbon Steel (C45)120 - 1400.088 - 0.132Emulsion / Through-Tool
Alloy Steel (42CrMo4)110 - 1300.088 - 0.114Through-Tool Recommended
Stainless Steel (304)100 - 1200.070 - 0.106High-Pressure Through-Tool
Cast Iron (GG25)140 - 1600.106 - 0.158Dry / Minimum Quantity
Aluminum (AlMg3)220 - 2700.132 - 0.220Emulsion / Air Blast

Operating Guidelines

  • Entry Surface: Ensure perpendicular entry or use a center drill/spot drill to prevent walk-off
  • Peck Cycle: Not required for depths up to 3×D; use 1×D peck for depths exceeding 5×D
  • Coolant: Through-tool coolant is mandatory for blind holes exceeding 2×D depth
  • Speed/Feed Ramp: Start at 80% of recommended Vc and increase in 10% increments to optimize tool life
  • Insert Inspection: Check insert seating and clamping screw torque (2.5 Nm) before each use
  • Tool Life Monitoring: Monitor hole diameter; retire when tolerance exceeds 75% of specified limit

Toolholder Compatibility

Recommended clamping systems for optimal performance:

Toolholder Type Interface Compatibility
Hydraulic Chuck5.4 mm★★★★★ Excellent Runout
Shrink Fit Holder5.4 mm★★★★★ Best for High Speed
Collet Chuck (ER16/ER20)5.4 mm★★★★☆ Good General Purpose
Side-Lock (Weldon)5.4 mm★★★☆☆ Moderate
