Product Description

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.

Key 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 and 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.
Product 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
