Spotting Drills

Scientific Cutting Tools’ Spotting Drills are engineered for precision and performance. Designed with a 4-facet point and constant web, these drills ensure accurate hole starts and minimize tool walking. A 20° helical flute promotes smooth chip evacuation, while the point angle is held to a ±1° tolerance for exceptional consistency. Finished with an advanced optional AlTiN+ coating, these solid carbide tools deliver extended tool life and reliable performance, even in demanding applications.
