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.
- 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.
