If you have used a wishbone type of riveting tool, you'll have to learn a new way. This is a ratcheting tool, it works differently. Takes a bit of a learning curve, but easily learned. Test a rivet or two first on a blank piece of metal. Well built, heavy duty, tool itself is heavy. Nice thing is it can be used in tight places. Odd thing is the nose cone, has two opposing flats for a wrench to assist in removal, but no wrench included. All it needs a flat open end 20mm wrench, but they are not common. I did find a flat, short one online, but they should include one. Nice case, pinned hinges, has large area the for rivets. Would like to see the case with independent sections for the rivets instead of cellophane packs. There is storage in the lid for all the mandrels, very snug in their respective slots. Large, clear, size markings on the end of the mandrels. Instruction sheet could be written better, had to guess at a few things. The manual is 4 pages, with the last two being blank. They could include a chart on what drill size to use for each size of rivet included with the set, and thickness tolerances of the material being riveted to. The instructions indicate a scale on the tool, it took some very close looking to find a tiny scale, a decal that cannot not be seen while using, supposedly to help set the stroke of the tool. Really, you have to trust “feel” to get it set right. Yes, it can work with aluminum nutserts. Overall, good tool for the money, would recommend it to any mechanic & sheet metal worker. ## Frequently Bought Together - TOLRET Rivet Nut Tool Rivet Nut Kit, Rivnut Tool Kit with 10 Metric and SAE Mandrels, 100 Pcs Rivet Nuts Assortment Kit, Professional Ratchet Nutsert Tool Kit with Rugged Carrying Case, TR21 - Vifmy Metric & SAE Rivet Nut Assortment Kit(300 Pcs), M3 M4 M5 M6 M8 M10 M12#8-32#10-24 1/4"-20 5/16"-18 3/8"-16 304 Stainless Steel Rivnut Set UNC Flat Head Nutsert - Kadrick Rivet Nut Kit, 810pcs SAE & Metric Rivet Nut Assortment Kit Galvanized Carbon Steel Flat Head Threaded Insert Nuts, Sizes 6-32 8-32 10-24 1/4"-20 5/16"-18 3/8"-16 M3 M4 M5 M6 M8 M10 --- ## 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/724827353-rivet-nut-tool-rivet-tool-kit-metric-sae-mandrel-m5](https://www.desertcart.co.uk/products/724827353-rivet-nut-tool-rivet-tool-kit-metric-sae-mandrel-m5) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
