Spot drills are used primarily to create a starting hole for a traditional drill bit, ensuring an accurate hole location for a secondary drilling operation. The shallow hole created by the spot drill prevents the traditional drill bit from “walking” or moving. The short flute length of these spot drills versus their overall length increases rigidity and strength, and reduces drill wander. These spot drills can also be used for chamfering, deburring, and countersinking. However, they do not have body clearance, and are not designed to drill beyond the point length.
