A pilot or spot drill, also known as a starter drill, is typically required when the succeeding drill is longer than 10xD or smaller than Ø 1.00 mm. Starter drills can also be used to improve hole location due to their short, rigid geometries.
The high-performance Nirox drill is available in diameters from 0.30 - 3.00 mm. It was developed for use at low cutting speeds and unstable environments.
We offer tool holder backup screws to control cutting tool length, clamping bolts for face/shell mill arbors, and Weldon screws for side lock end mill holders.
An extensive lineup of unique micro and high-performance drill geometries with a wide range of diameters and lengths capable of optimizing productivity and cost per hole.
