  • Operation 1, Choose proper size mandrel to set nuts on workpiece
  • 2, Test some nuts before application to get proper torque setting(your drill must feature clutch and torque setting to avoide over loading)
  • 3, Hold steady--right drive to press the nuts and stop when nuts grip tight enough--left drive to withdraw mandrel
  • Tips: 1, choose as big size as possible since small size mandrel and thread are thin and easily stripping.
  • 2, mandrels are wearing parts, and we provide replacement mandrel for further purchase.

I haven't used the tool just yet but upon opening the kit and installing different mandrels......super easy. They're are like 12 different mandrels! Every size you could possibly need. Will update this evening after work..... update 10/13....I tried this on some stock Aluminum and 3mm ABS plastic and it worked perfectly, this tool is going to be so helpful on my ebike which is made of aluminum and ABS plastic! Can mount anything i can think of. Love it just wish i had it when I first got my ebike 3yrs ago, the build process would have been much different and probably better.

con menos de 30 usos ya tuve que comprar repuestos para M4, funciona bien pero no me parece que los machos (roscas) sean de buen material.

So much better than the plier style. Friggin awesome addition to a toolbox. Nice little carrying case. Just make sure not to full send give it the beans using a drill/impact driver- sinks the rivets quick... I mean NOW. First time I used this was a test piece using a GEN 1 Milwaukee 1/4" impact driver.... ZZZZZZZZZZZZIPPPPPPPPP *PING* oops-- ripped the threads right out of the rivet. Switched to a brushed Milwaukee drill/driver/hammer combo in high-worked but man that bottom end grab will wrench on ya, put the drill in low-- much better but dam still quick and now even wrenches harder, put in low in screw mode and even better as your wrist doesnt try and become a bendy straw.If you got the plier squeeze style, GET THIS THING!!!!!!!!! Looks cool too

The 1/4-20 mandrel stripped immediately upon using a high quality rivnut. The mandrel threads are made of super soft metal. The design and functionality of the tool seems great, however it is made so cheaply, it was immidiately useless on the first day of use. I would much rather pay more for a better quality tool. This is pure trash.

This is an amazing tool. I used to have the push inward, large, bulky tool. This fits into small tight areas with ease. I use threaded rivets more often now.

I had a time sensitive project that needed this and they straight up, bait and switched when shipping the item. Since Amazon has no method to rate sellers, which is very suspicious. I am rating the product.

This is my new favorite tool! I've been rivenuting everything that I can now. Easy to use. Compact enough to get into tight places. Works amazing. Extremely happy with it.Tip: use a drill with the clutch setting turned down about halfway and tune it in from there. Don't use an impact. I ruined a couple that way.
