Spot & Chamfer Drill Bits

Implementing spot & chamfer drills can improve the hole location and tool life of a succeeding drill. Spot drill bit 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 bit. A spot drill creates a consistent surface for the more delicate and expensive deep hole drill to enter the part.
