Threaded insert into existing concrete?

    I bought a new tubing bender and I’d like to anchor this one to the floor instead of bolting it to my welding table. Space is at a premium and I want to be able to move it. I do not want threaded rod sticking out of the floor when it’s not in place. Is there a threaded ‘insert’ option? Do they typically perform well? I’m hesitant to drill 4 bigass holes in my shop floor only to have the inserts pull out.

    I've used Hilti threaded inserts at work on many occasions and they work well. We use the epoxy versions and they react out many tons of load, but tear out is more a function of the concrete slab and bolt pattern than it is the anchor.

    They use threaded inserts for car lifts so I imagine if you could use those, you'd be fine.

    We use regular Hilti HDI-P which is a short drop in anchor. Since it's on the floor you may want to go with a deeper anchor just in case crap falls into it when you're not using. Depending on how good your garage floor is, you may want to investigate the epoxy set anchors. When I set some drop-ins on my patio for a post I ended up spalling a couple holes out. Plus, with the epoxy I don't believe you need a setting tool like you would with a drop-in.

    Get/make (cut the head off a bolt and put a slot in the end) some grub screws to put in the anchors when not in use.

    I use the 2nd from the top of the mcmaster link for my bender. I only use it a few times a year, so it's easy to blow the holes out when dirt gets in there, or stick the shopvac nozzle over the hole. I need to make another plate with the same hole pitch for my cheapo tire changer as the stump I had it lag bolted too in the backyard finally rotted out enough lol.

    Exactly what I’m worried about. Lots of good info here tho, those from McMaster should do the trick.

    This. Make sure your concrete is heavyweight enough or a high enough PSI that you won't end up destroying it. If it were me, I would make sure your inserts are at least 4" apart and 4" from the slab edge.

    We used to use a LOT of those drop ins as we were always moving cells around. Had about an 85% success rate with them because either your drill would walk or the hole would oblong, the concrete would flake, or after a few uses they would just loosen up. I would look at the epoxy ones first.

    Just used those redheads to mount my tire changer in my floor about a week ago. Haven't used it to test them out but seems stable enough. Drilling holes into concrete is a bitch but a little trick I used was when you hit a "dead spot" (where you're sitting there and the hammer drill is working but you're not making any progress), I would take a chisel and a mini sledge to break up whatever impediment it hit and that would get the wheels of progress spinning again.
