Internal Coolant Step Drill for Aluminum Carbide Multi Diameter Drill Bit with Coolant Holes

Introduction:

This high-performance carbide step drill is specifically designed for aluminum machining, featuring internal coolant channels and a multi-diameter design to streamline drilling, chamfering, and deburring in a single operation. Engineered for CNC machining centers, it delivers superior chip evacuation, reduced heat buildup, and extended tool life—ideal for high-volume aluminum production.

Features:

Internal Coolant Channels (Through-Tool Cooling)

  • 2-4 precision coolant holes (Ø1.0-1.5mm) for direct lubrication

  • Reduces heat & prevents built-up edge (BUE) in sticky aluminum alloys

Multi-Diameter Step Design

  • Integrated diameter transitions (e.g., 6mm → 8mm → 10mm)

  • Eliminates tool changes for drilling + chamfering in one pass

Optimized for Aluminum

  • Polished flutes minimize chip adhesion

  • 3-4 flute spiral design (30°-45° helix) for smooth chip evacuation

Solid Carbide Construction

  • Micro-grain carbide (K30/K40 grade) for wear resistance

  • Sub-micron grain structure ensures edge sharpness

High-Speed CNC Ready

    • Balanced geometry reduces vibration at 15,000+ RPM

    • h6 tolerance shank for precision collet/chuck mounting

Advantages:

40% Faster Machining – Combines drilling + chamfering operations

2X Longer Tool Life vs. HSS drills (no edge welding in aluminum)

Mirror Finishes (Ra ≤0.8µm) with polished flutes


No Chip Clogging – Coolant + spiral flutes clear chips efficiently

Application:

Electronics

  • Heat sink mounting holes (6061/6063 aluminum)

  • PCB fixture plates

Automotive

  • Lightweight engine blocks (A380 die-cast aluminum)

  • Battery tray drilling

Aerospace

  • Aircraft structural components (7075-T6)

  • Drilling + chamfering in thin-wall parts

General Machining

  • Multi-diameter holes in aluminum extrusions
  • Deburring soft alloy castings
