The presetting machines available today are accurate, easy to use and provide closed-loop tool compensation on the CNC machine tool, saving significant time during job change-over.
Many factors may go into the decision to invest in a presetter such as tool budget, accuracy needs or delivery time. We’ve put together a reference guide.
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.
