NC Spot Drills
Enhance hole positioning and accuracy with Kennametal NC (Numerical Control) spot drills. These high-performance solid carbide spot drills are designed for pre-centering operations for more controlled drilling operations. These tools feature short flute lengths, providing stability and minimizing any potential deflection during the initial stages of hole preparation. Our NC spot drills are available for chamfering, tapping, and protecting the cutting edges of solid carbide drill lines. For continuous improvement with your machining operations, Kennametal's NC spot drills are the perfect choice for achieving superior hole quality and positioning accuracy.
