The KSV Looms Series II, Series III, and Deutsch Autosport drill jig set is designed to be used bin in conjunction with Blair Rotabroach Holcutter sheet metal cutters. We have used the Blair Rotabroach Holcutters to cut bulkheads holes exclusively for a number of years. They provide a clean accurate cut in steel, aluminum, and composite materials with results superior to traditional hole saws. After cutting a clean hole for the main body of Series II, Series III, or Deutsch Autosport connector, we were still left to drill the small holes for the nut plate hardware on the flanged connector. This process is tedious and made difficult by the tight locations that most bulkheads end up being located in.
Our drill jigs are meant to simplify this process, even if you’re upside down, under a dash, and using a 90 degree drill. Simply cut the main hole for the bulkhead, insert the drill jig, drill the first hole for the hardware, insert the alignment pin and drill the remaining holes for the hardware. The set comes with shell sizes 12 to 24 and can be used on narrow flanged Series II, Series III and Deutsch Autosport connectors.
Drill Jig Set Includes;
Drill Jigs for Series II, Series III and Deutsch Autosport x 7 (shell sizes 12 through 24)
1/8” Alignment Pin x 1 (used for shell sizes 12 through 22)
9/64” Alignment Pin x 1 (used for Shell Size 24)
