Product Overview

The Kyocera 1/4 DRILL 2FL 5XD TX IC SGS56446 is a premium solid carbide drill engineered for high-performance CNC machining operations. Featuring an advanced TX IC grade substrate with multi-layer PVD coating, this drill delivers exceptional wear resistance, superior chip evacuation, and extended tool life in demanding production environments. The 5XD length-to-diameter ratio provides optimal rigidity for deep-hole drilling applications while maintaining precise hole tolerance and surface finish quality.

Operating Guidelines

  • Coolant Recommendation: Use high-pressure coolant (≥70 bar) for optimal chip evacuation in 5XD applications. Minimum 5% oil emulsion concentration recommended.
  • Peck Drilling: For blind holes exceeding 2×D, implement a peck cycle with 0.5×D peck depth and full retract to break chips.
  • Entry Angle: Ensure perpendicular entry (±1°) to prevent uneven wear on cutting lips. Use spot drilling for irregular surfaces.
  • Spindle Runout: Maintain TIR ≤0.0002" at the tool tip to maximize tool life and hole quality.
  • Tool Overhang: Minimize overhang to 3×D or less. For 5XD applications, use hydraulic or shrink-fit holders for maximum rigidity.
  • Feed Rate: Reduce feed by 30% for the first 2mm of entry to prevent chipping on the cutting corner.
