many industrial circles, it is known for the smallest drill ever produced. And another of its most notable claims to fame is when the shop’s founder John Cupler drilled a hole through a human hair measuring only 0.003" (0.08 mm) in diameter on national TV back in the 1950s. Today, National Jet continues to push the micro-drilling envelope. And while the shop still relies heavily on special in-house designed and built proprietary manual equipment, it suc- cessfully performs a good portion of micro-drilling work on its CNC machin- ing centers. This shift of work was possible not only because of the im- proved capabilities of modern machine tool technology, but also due in large part to the shop’s incorporation of an advanced, extremely high-precision toolholding system.
National Jet considers 0.010–0.015" (0.25–0.38-mm) diameter holes as big. They are the size holes that are done on CNC equipment that automates the micro-drilling process. But it should be noted that the shop has drilled holes as small as 0.005" (0.13 mm) in diam- eter on those same CNC machines. Basically the only limitation in terms of the smallest drilled hole diameter is whether or not a drill has through-tool coolant capability. Regardless of their somewhat larger size, these are still very critical holes. And besides machine tool capability, the operation requires highly precise tooling as well, which is why the shop uses Rego-Fix collets and the powR- grip (PG) toolholding system. Currently, well over 50% of all the
shop’s CNC machine tooling is now Rego-Fix. Together with the CNC machines, the tooling provides National Jet essential process consistency and performance reliability along with increased tool life. All contribute to higher-quality holes as well as milled
part features. But most important, the Rego-Fix tooling gives National Jet the confidence and peace of mind to run its micro-drilling operations untended for increased overall production output and speed.
