Video: 1964 Game Show Demos Drilling through Human Hair

See a clip of the founder of Maryland’s National Jet on the “I’ve Got a Secret” game show demonstrating his company’s ability to drill through something as small as a human hair.

A number of years ago, I visited National Jet in LaVale, Maryland to develop this article describing its micromachining and micro-drill-manufacturing capabilities. Recently, I happened to learn that the company’s founder, JA Cupler, appeared on the game show “I’ve Got a Secret” back in 1964. This video shows the clip, which is interesting to watch for nostalgia’s sake and the drilling demo. During the demo (this starts around time mark of 6:00 if you want to skip ahead), a National Jet machinist drills a hole through a strand of hair (about 0.003-inch in diameter) using a 0.001-inch diameter drill.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
