2 Flute Internal Coolant Carbide Step Drill Bit AlTiN Coated for Hard Steel Stainless High Precision CNC Milling Tool

Introduction:

Our premium 2-flute internal coolant carbide step drill bit represents the pinnacle of CNC machining technology for hard materials. Precision-engineered from solid tungsten carbide and enhanced with advanced AlTiN coating, this specialized step drill combines exceptional durability with superior cutting performance. The innovative internal coolant design allows for efficient heat dissipation during high-speed operations, while the unique 2-flute configuration ensures optimal chip evacuation in demanding applications.

Features:

Advanced AlTiN Coating:

• • Superior heat resistance (up to 900°C)

  • 3-4x longer tool life compared to standard coatings

  • Reduced friction coefficient for smoother operation

Internal Coolant System:

• • Precision coolant channels for maximum heat reduction

  • Improves tool life by up to 40%

  • Enables higher cutting speeds and feed rates

Premium Tungsten Carbide Construction:

• • Ultra-fine grain structure for exceptional toughness

  • Maintains sharp cutting edges longer

  • Resists deformation under heavy loads

Optimized 2-Flute Design:

• • Superior chip evacuation capability

  • Reduced cutting resistance

  • Minimized vibration during operation

High-Precision Manufacturing:

• • Ground to micron-level tolerances

  • Perfectly balanced for high-RPM applications

  • Consistent performance across entire tool life

Advantages:

• Extended Tool Life: AlTiN coating combined with internal coolant delivers up to 5x longer service life in hard materials

• Higher Productivity: Enables 20-30% faster machining speeds compared to conventional drills

• Superior Surface Finish: Precision-ground cutting edges produce excellent hole quality

• Reduced Downtime: Exceptional wear resistance minimizes tool changes
