... and is used for rough machining. Carbide drills come in three forms: solid carbide drills of diameters of 8 mm (0.3 in.) and less, drills with brazed tips, and drills with indexable inserts for diameters of 14 mm (0.6 in.) and above. Carbide drills need to be used at much higher speeds than high-speed...
