Astro Pneumatic Tool ADN14 Rivet Nut Drill Adapter Kit

As a machinist, quality tools not only function well, but also are a pleasure to hold with just the right heft, fit, and finish. How well the tool functions is what really matters, though, and this Astro Pneumatic ADN14 Rivet Nut Driver is top-shelf. For what it does, hold a rivet nut and compress the threaded end down onto the flanged end, the Astro exceeds even my obsession for the best tool at a fair price.Rather than using a makeshift rivet nut compression method like a nut, bolt, and washers I opted to get the tool. Always great to have a bonafide reason to get a new tool, amiright? I'm new to installing rivet nuts, although the process is rather straightforward and, with so many tools available on the market with varying reviews, it was a struggle to choose the 'right' one with quality/value balance.So, if you're interested in setting rivet nuts, the first decision hurdle is which compression method: manual (plier) or powered (drill-driven like this model ADN14). My priority was focused on having a small enough tool where clearance to set the rivet nut wouldn't be an issue. This was paramount, as so many applications are in tight spots with limited reach, which ruled-out compressing plier handles. Decided on the drill-driven model because of the clearance provisions. A consideration for plier/drill choice is can the user 'feel' torque or have an adequate drill clutch to control compression in order to 'set' the rivet correctly. I use a Milwaukee 12V 1/2" drive drill (my EDC) although the Milwaukee clutch won't hold the torque to full compression, but in the drill mode this little torque'r can sprain your wrist, so the issue was learning the 'feel' and knowing when to release the trigger. After a couple test sets, I was able to reliably set 1/4-20 steel rivet nuts.My first project is nuts in our Discovery engine hatch. The OEM hatch wasn't adequately designed, so a mod was in order. Setting 1/4-20 flat head stainless screws around a 3/4" marine grade hardwood plywood on 1/8" AL angle brackets. Setting 16 screws (think Airstream rivet pattern) over an oak flooring replacing carpet (eww).I'm not certain, but I do believe the plier-type may provide consistent, reliable compression with little needed operator 'feel' but again, at a loss of confined applications. So, if you're able to work with your hands and want a commercial grade, professional rivet nut setter, the ADN14 should more than meet your needs. I'm very impressed with the whole package - the wide selection of SAE and metric dies, collet wrench, all stored in a sturdy carry case. The set is compact, has the appropriate heft, and fit & finish which feels great in the hand, and screams quality. Value meets quality.I've also been using the Astro 3018 Digital Tire inflator for a couple years and am also very impressed. Astro Pneumatic tools are 'sleepers' and I for one am very glad I've found them. Will be looking for more of their tools.

Well built, great feel, however, has some limitations setting stainless rivnuts in 1/4”x20. I am using a Makita 18 volt with 21 settings available. Can be difficult. I did have success doing 1 SS rivnut set on “drill” but I won’t do it again fearing damage to my drill. No problem installing smaller size stainless and no issue with regular steel in 1/4”x20 installing was a breeze with those, the larger size SS problematic. (Maybe there is a “lesser” hardened rivnut available). After reading many comments I decided to order some replacement mandrills and nosepieces in advance just to be on the safe side so as not to have problem in middle of job. Buying a replacement part in advance for a tool at this price is something to be considered. Still rate it at 5 stars with the one exception. If required to do many SS rivnuts in larger sizes, I would suggest manual setter. One other issue is the case; for larger size mandrills it requires some effort to get them to seat properly. On side note, if doing regular “pop” rivets, I purchased the tool (from same seller) for those, and installing them was fast and perfect. Hope this helps….

Used heavily in our shop, but since I don't like to share, I got my own.We have learned to not use a drill or especially an impact driver when setting inserts. Instead, we use a low profile / close quarters 1/4" ratchet wrench. A ratcheting combination wrench would work, but the close quarters ratchet wrench tends to be able to lock onto the shaft, minimizing slipping off.Before we figured out the ratchet wrench method, we were snapping shafts every so often. Just use a close quarters ratchet hex wrench, only takes a few moments longer for inserts up to quarter inch or so.

Very very useful if you're setting multiple rivet nuts. Be prepared to lose some rivet nuts while you figure out the correct settings for the drill you're using with the type of rivet nut. Once you figure it out though it makes setting rivet nuts fast and reliable. The rest of the guys in the shop borrow it everytime they need to set some!

Awesome tool. I would never buy a hand rivnut tool compared to this. Gets in tighter spots and works faster. I use it at work frequently. Do NOT use with impact drivers. I modified mine to fit a US impact driver and thought it was great for a while. The impact driver broke the refrained clip three times and then sheared the guide pin though and I never hammered it hard. Still a great tool. Not for impact drivers thoughs.
