2 Flute Carbide Step Drill Bit Straight Flute Uncoated Coolant Through Hole For Steel Metalworking Cnc Machining Centers


Introduction:


This precision carbide step drill features a 2-flute straight-flute design with internal coolant channels for efficient chip evacuation and cooling during deep-hole drilling operations. Manufactured from high-grade micro-grain carbide, this uncoated drill bit delivers exceptional rigidity and wear resistance for machining steel, stainless steel, and other tough metals in CNC machining centers.


Features:


Premium Micro-Grain Carbide Construction

  • Superior hardness and heat resistance compared to HSS or coated drills

  • Maintains sharp cutting edges longer in abrasive materials

Optimized Straight Flute Design (2 Flutes)

  • Provides excellent stability and reduces vibration

  • Ideal for rigid setups and precise hole positioning

Internal Coolant Through (ICT) System

  • Directs high-pressure coolant to the cutting edge

  • Extends tool life by reducing heat buildup

  • Improves chip evacuation in deep-hole drilling

Step Drill Geometry

  • Multiple diameters in single tool for efficient machining

  • Eliminates need for tool changes when creating stepped holes

  • Suitable for chamfering and deburring in same operation

Uncoated Cutting Edges

  • Optimized for applications where coatings may flake or chip

  • Can be re-sharpened multiple times

Advantages:


Longer Tool Life - Carbide construction withstands higher temperatures than HSS


Improved Productivity - Combines drilling and chamfering in single operation


Better Surface Finish - Straight flute design produces excellent hole quality


Cost Effective - Uncoated version offers excellent value for general applications



Applications:


  • Materials: Carbon steel, alloy steel, stainless steel (304/316), cast iron, non-ferrous metals

  • Operations:

    • Deep hole drilling (with coolant through)

    • Stepped hole drilling (multiple diameters)

    • Chamfering and countersinking

    • Precision hole machining in CNC centers

  • Industries:

    • Automotive component manufacturing

    • Mold and die making

    • General metalworking

    • Aerospace part production
