1/4" (6.3 mm) hexagonal clamping system. Hitachi twist drills are suitable for almost all types of wood.
The centering tip has a self-tapping conical shape that, by rotating, advances itself in the wood and facilitates the centering of the hole.
Due to the fact that the force of penetration is facilitated by the shape of the drill, its penetration does not require high rotation speed and does not face the high resistance of the wood, it increases the life of the drill and of the machine.
