Wild Heerbrugg - Kern Instruments PUG3 Point transfer drill bits-Photogrammetry

Description

Wild Heerbrugg - Kern Instruments PUG3 Point transfer drill bits-Photogrammetry. Condition is "Used". These high precision miniature drill bits were used in a special aerial photogrammetry application to place very tiny holes in the emulsion of aerial film for use in transferring terrain points between 3D stereoscopic photographs in a process called aerotriangulation. The chisel type point would drill a small spec in the film that was approximately 60 microns wide when inserted into what was known as a point transfer device. They could be used for a similar application, or kept as a nostalgic piece of history in the field of Photogrammetry.
This set contains 9 (nine) units, complete with their respective protective point cover sleeves.
The "key" as pictured is not included in the sale, but helps to reveal the approximate size of the drill bits, which are approximately 2-1/4" long and about 1/8' of an inch in diameter.
Sales outside of Continental USA will require a customized cost for shipping, depending on location.
