Nice heavy duty nut rivet tool. It makes easy work of installing the rivet nuts. It comes with a plastic case and nice variety of SAE and metric mandrels. The kit includes 200 rivet nuts in a variety of sizes. Great tool for the money!

I'm just now starting to get into fabrication and was originally looking at pop rivets instead of this and I'm glad that I decided to go this direction.First off this is a serious tool that is much higher quality than I was expecting. The tool itself is very heavy and durable. I don't think this will break with the minor work that I will be doing with it. The fact that it contains different size rivet nuts and adapters is a nice addition, so you can get started immediately.Overall I am very happy with this unit and I expect that I will be using this for many years to come.

This made installing threaded rivets for my Jeep fenders very easy. The multiple sized heads made this a very versatile device. Everything packs into the plastic case.

The rivet nut setting tool, model K1, by Corwin Machinery, is made in PRC (china). The K1 comes in a decent case with a light duty plastic seam hinge. The K1 tool itself is 16 inches long to get a good amount of torque on setting the larger size steel rivet nuts. I do like the assortment of mandrel sizes that are included, fifteen in total covering both SAE and metric. The K1 is very similar to my Astro made rivet nut setting tool. This has been a good tool so far.4 stars

Very easy to use as long as you have a lot of overhead room.Comes with all of the basics, but once you know what sizes you're going to need you can easily order more rivet nuts.

growing up in a construction family & being mechanically inclined myself, i've used plenty of rivet nut tools over the years & most of them have been disappointing. this corwin k1 is on a completely different level - truly professional grade that makes installing threaded inserts almost enjoyable.the build quality is immediately apparent - substantial weight, precision machining & thoughtful design elements throughout. the 16" handles provide serious leverage that makes setting even larger rivet nuts effortless compared to shorter tools. the stroke scale is genuinely useful rather than just a marketing feature, allowing precise setting depth for different materials.the mandrel system is brilliantly designed - quick-change with secure locking that doesn't come loose during use. having 15 different sizes covering both metric & SAE means you're prepared for virtually any project without needing additional purchases. the storage system in the case keeps everything organized & prevents losing the smaller mandrels.performance is where this tool truly shines. sets rivet nuts cleanly & consistently with minimal effort thanks to the leverage advantage. the thread quality is preserved without distortion even in thicker materials. recently used it extensively while fabricating mounting brackets for my salon equipment & every single rivet nut set perfectly the first time.including 200 assorted rivet nuts organized in separate boxes is incredibly generous & gets you working immediately. the selection covers the most commonly used sizes & the quality of the included fasteners is excellent - not the cheap pot metal ones that strip easily.the carrying case deserves special mention - unlike many tool cases that fall apart quickly, this one is robust with quality latches & hinges. everything has a dedicated place & the layout is logical for quick access. even includes space for additional rivet nuts beyond those that come with the kit.my husband, who typically prefers his own tools, borrowed this for a project on his f150 & immediately commented on how superior it was to the cheaper one he'd been using. even my construction veteran father was impressed by the build quality & smooth operation.if you do any significant amount of fabrication, auto work, or general repairs where threaded inserts are needed, this tool is absolutely worth the investment. pays for itself quickly in time saved & frustration avoided compared to lesser tools. one of those purchases where you immediately recognize the value of paying for quality.
