3-Flute Carbide Drill Bits

Why Choose a 3-Flute Carbide Drill?

Solid Carbide 3-Flute Drill Bits are designed for high-performance production machining where speed, accuracy, and tool life matter. Compared to traditional 2-flute drills, the 3-flute design provides a stronger core for increased rigidity while maintaining excellent chip evacuation. The result is improved hole quality, reduced deflection, and the ability to run higher feed rates in rigid CNC machining centers.

Manufactured from premium sub-micrograin solid carbide, these drills feature a precision-ground 150° split point for accurate positioning and consistent performance. The TiN coating helps reduce friction and improve wear resistance, extending tool life in demanding applications.
