The Astro Pneumatic Drill Adapters, Nos. ADR14 and ADN38 XL, convert cordless tools into a power-pop riveter or rivet nut setter. Made from CNC machined billet aluminum and CroMo, these adapter kits include multiples sizes up to 1/4” pop rivets for the ADR14 and 3/8-16” rivet nuts for the ADR38 XL with aluminum, steel, or stainless hardware. The 1/4” shank fits most cordless drills and drivers and requires a torque limiting clutch for rivet nuts. For large sizes, 18V or higher is recommended.
