Good in tight quarters, works in a different way. Nice storage case.
This is a very different nutsert tool. 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.

Professional Quality
Where has this tool been all my life? Excellent quality tool that covers both metric and inch sizes. I just reinstalled the running board on my truck using this and it worked as any professional quality tool should.

Worked really well
I was skeptical due to the price but it feels like a heavy duty, well built tool. I needed to put a rivnut in an area where the long handle style tools wouldn't fit and this worked like a charm. There's some YouTube videos showing how to use it too.

Sturdy, well made product
I recently purchased this product to drill holes and install rivnuts to mount a hitch on a tubular steel frame on a zero turn mower. It worked well. My only complaint is the short handles could make it a bit challenging to set some rivets if they were made of a harder metal due to the tool's limited leverage. Overall a good product for the money.

Simple, great for tight spaces.
I love this tool, easy to use and fits in places where a normal rivnut tool wouldnt. The ratcheting mechanism is nice because you can feel how much the rivnut is being crushed.

Aunque es bastante cara vale la pena invertir en esta herramienta, compré la más económica y no duró ni dos remaches, en cambio está lo hace de madera fácil y rápida
