|Unit Of Measure||Each|
The purpose of spot drilling is to drill a hole that will act as a guide for drilling the final hole. Spot drills are superior to centre drills predominantly due to their increased stiffness. Their single size also makes it easier to run them at the correct cutting speed, as opposed to the dual tip sizes of a centre drill.
