Spotting Drill Sizes
Spotting or Centering Drills are designed for centering work, making a starting hole for a larger drill and for chamfering. The short flute and overall length of these type drills is very rigid to ensure precise spotting prior to drilling. Use as large a drill diameter as is reasonable for the best results.
