Micro Spot Drills

Using micro spot drills can improve hole location and tool life of a deep hole drill or micro drill. Spot drill geometries are short to optimize rigidity and accuracy with a point angle larger than succeeding drills to guide them towards the hole's centerline. Parts often have rough, angled, or curved surfaces leading to poor, inconsistent tool life without using a spot drill. A spot drill creates a consistent surface for the more expensive deep hole drill to enter the part.
