Product Overview

This high-performance solid carbide step drill bit features a 140° point angle and straight flutes, optimized for precision drilling in CNC machining. The internal coolant channels enhance heat dissipation, extend tool life, and improve chip evacuation in demanding materials like stainless steel, hardened steel, cast iron, and aerospace alloys.

Key Features
  • Material: Solid carbide (ultra-hard, wear-resistant)
  • Point Angle: 140° for reduced thrust force and improved centering
  • Flute Design: Straight flutes for efficient chip removal in deep holes
  • Coolant System: Inner coolant holes (through-tool coolant) to reduce heat and prevent workpiece/tool damage
  • Application: CNC machining, mold making, automotive/aerospace parts, and high-precision multi-step drilling
  • Coating Options: Optional TiAlN/AlCrN coatings for higher heat resistance
Performance Advantages
  • Longer tool life due to carbide durability and coolant support
  • High rigidity minimizes deflection in deep holes
  • Multi-diameter steps allow graduated hole sizing in one operation
Typical Applications
  • Drilling, chamfering, and deburring in one pass
  • Hard materials (HRC 45+), composites, and exotic alloys
