Application: For centering and countersinking especially on CNC machines. For even better positioning we would recommend TITEX PLUS Maximiza Solid Carbide Bore-Drills A1166 (page 167). Maximiza solid Carbide Bore- Drills can be used in the same way as NC-Spotting and Chamfering Drills but at much higher cutting speeds. Due to the higher rigiditiy of carbide and its stiffness positioning accuracy will be even higher.
