The Phantom HSS Enlarging Drill (three-fluted drill) according to DIN 343 MT is specifically designed for machines with a Morse Taper spindle. Manufactured from high-quality HSS, the MT shank guarantees perfectly centered and slip-free power transmission, even at high torque. This drill enlarges existing holes with high precision. The stable, three-flute design effectively restores the shape of out-of-round bores, resulting in a perfectly round and dimensionally accurate final result.
