Let me know KIARUO Pneumatic riveting gun Review: Very Nice Tool - Was worried of the quality. This unit is solid. Heavy duty quality for a lifetime of rivet work. Quick response fwd/rev. There are no real consumables aside the rivets. The head units quick release is insanely thought through. Super easy and effective. Replacement heads are cheap. I would recommend this to anyone needing a dependable tool. Done with the manual style tools. Lol Review: This is a good tool. - I’ve had an interesting journey with this tool. I’m on my second one but that’s a good thing. I originally bought this tool from desertcart and was very disappointed with it. I had a big problem with the mandrel getting stuck in a partially installed but not completely crimped, spinning rivnut. It was very frustrating. I had to use a hacksaw several times to cut the tool free from the project as the mandrel would become seized inside the rivnut. I wound up returning the tool and writing a scathing review of the product. A few months later, I received an email from the company. They had read my review and wanted to make things right. They were offering to ship me a free tool if I would be interested and spent some time explaining why I was having the problems that I was. The bottom line? The mandrel needs to be greased, frequently, to prevent it from heating up. Evidently, when it heats up, it pulls off some of the zinc coating on the steel inside the threaded portion of the insert and this material gets jammed up in between the threads. This happens before the insert is fully compressed which will cause it to spin within the work after the mandrel seizes up. With the first tool that I had purchased, this seizing problem was occurring every 3-6 installations. In hind sight, it was this quantity of rivnuts that allowed the ungreased mandrel to build up enough heat for problems to begin with subsequent installations. During my emails back and forth with the company, they asked how long the air hose was in my setup. (Any of you pneumatic tool users know about having to adjust pressure to compensate for long runs of hose.) They made specific recommendations for my particular set up for air pressures for each of the different sizes of rivnuts that can be installed. They were very patient with my questions and concerns and willing to listen to and address various points that I brought up. I was impressed with their customer service and believed they were a good company to work with so I took them up on their offer to retry the tool at their cost. They shipped one out to me immediately. When I received the new tool from the company to try, I decided to waste a bunch of rivnuts in a test to see if everything that I had been told was accurate. I started by setting my air pressure according to their recommendations. Then, dipping the mandrel into some grease every two or three rivnuts to ensure that it was always lubricated, I successfully installed 30 rivnuts in rapid succession without a single failure. I was very pleased. The tool worked flawlessly. It was painfully clear that lubrication was an important part of the process and something that I paid dearly for in not doing so with the first tool that I used. In retrospect, I went back and looked more closely at the desertcart product page and sure enough, they do recommend that the mandrel be greased, although the documentation that came with the product I found to be lacking. There are plenty of situations where the person using the tool may not be the one who purchased it and may never see the instructions. (Example: A gift from someone else or an employee in a company who is handed the tool and just told to use it.) I think the company that makes this tool would benefit from placing some kind of sticker or label on the tool that has to be physically removed by the user before they can operate it the first time. This label should clearly state the importance of lubricating the mandrel, frequently, during use to ensure smooth operation. I mentioned this to the person I was emailing with as well. They seemed very receptive to the idea. Overall, I am pleased to be happy with this tool. I’m pleased that the company took the time to reach out and explain to me what I was doing wrong and offered to replace the tool at their cost in order to make my experience with it a better one. You don’t see this kind of behavior much with companies these days. As a result of this experience, I took down my old one star review and replaced it with this one. The company did not ask for this. There were no conditions placed on me for the receipt of a free tool. I’m happy to change my review as I see that the tool works quite well when used properly. The only other recommendation I might ask the company to consider would be to put a better muffler on the air outlet of the tool. It is quite loud during use. The plastic screen over the exhaust port does little to quiet the noise. This is easily remedied by wearing ear protection, however, and isn’t a deal breaker for me ay all. Five stars for this product and the company that stands behind it.

Thank you for the help! ### ⭐⭐⭐⭐ Very good tool, noisy *by W***N on March 12, 2024* This pneumatic rivet nut gun is a very good tool for DIY enthusiasts and professionals, offering excellent performance, ease of use, versatility and durability. Its pneumatic operation is noisy (so wear ear protection) and its interchangeable chucks and nosepieces provide flexibility for a variety of projects. Its construction is heavy compared to plunger models, but the tool feels sturdy and well-built, which makes it a worthwhile investment for anyone who performs daily tasks. The marking of the rivet head is a differentiator, which helps with quality control (very visual). ## Frequently Bought Together - KIARUO Pneumatic Rivet Nut Gun with Self-locking Head Gun 1/4 & 5/16 & 3/8 Mandrels,Industrial Grade Adjustable Speed Pull Rivnut Gun Model:LM07 Button Switch - KIARUO M6 M8 M10 Metric Self-Locking Rivet Nut Gun Head, Use for Model LM07 Pneumatic Rivet Nut Gun - KIARUO 1/4 Replacement Mandrel,Rivet Nut Gun Tip Mandrel 10pcs for Pneumatic Rivet Nut Gun --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/167353100-pneumatic-rivet-nut-gun-with-self-locking-head-gun-1](https://www.desertcart.co.uk/products/167353100-pneumatic-rivet-nut-gun-with-self-locking-head-gun-1) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
