Happybuy 4 Inch ACCU Lock Down Vise Precision Milling Vise 4 Inch Jaw Width Drill Press Vise Milling Drilling Machine Bench Clamp Clamping Vice(4")

Nice piece, works well

I expected this to be a crappy Chinese vise I used to have 15 years ago.I used a Kurt DX6 before so I’m comparing this $120 to a $700+ vise. It’s not a Kurt, but surprisingly…it’s the same in regards to functionality.It holds a part with good accuracy. Parts do not shift at all with heavy clamping from one edge. Not even 0.0001”. Yes. Tenths gauge is rock solid when I put half my body weight on the vise screw. Just like a Kurt DX6.Make sure to wear gloves and spend an hour deburring all the knife edges it has. They will split your hand open easily.Moving the jaws isn’t as smooth. A Kurt glides like glass. This vise felt stiff. Lots of cleaning and using proper way oil helped.Just be glad there’s a good option like this if you’re just starting out. Great for a home gamer.I’m using it on my CNC. If you want a dual or triple vise setup on your table at home this starts to make a lot more sense. $1500 vs $250 is kind of a wild difference.Just make sure your table is big enough if you get the 6”. These vises aren’t small.

Reviewing my new Happybuy 5" Accu Lock Vise. Vise arrived in a sturdy cardboard box partially filled with styrofoam surrounds, box was a little beat up but that's just from the shear weight of the vise and not having a styrofoam top liner (which should be included, that would have prevented all the shifting around in transport).Measurements (which everyone wanted to know) are as follows: 14 3/4" long without handle attached. 7 1/4" wide base flange to flange tips. 4 3/16" tall, 5" jaws, a big 5 7/8" max jaw opening (the ad only claims 5"), heavy 3/4" dia lead screw, 1 9/16" jaw height, 6 1/4" center to center base bolt down holes and a stout 36 pounds total.This is a very nice vise for the money. It arrived pretty clean (no metal shavings) with a very light coating of clear oil, all milled edges are razor sharp, crisp and very flat and smooth, the painted casting areas are nice with only a few sharp jagged spots. The paint job is great with a nice blue-green hammered look. The bag of included hardware is as others say a bit on the cheap side but that's not a big deal to upgrade and replace yourself.I spent about 3 hours cleaning, scraping, filing, sanding and oiling the vise. The entire inside lenght of both ways had some paint overspray on them that kept the jaws from moving easily. The two square cutouts up front had some razor sharp jagged edges that needed to be hand filed down to avoid seriously cutting yourself on. The entire bottom edge is also very sharp which I lightly filed and sanded back to avoid cuts as well. A very light coating of oil was applied to all bear metal surfaces to prevent rusting. I can turn the vise with just my fingers now without having to use the handle, which was impossible before fine tuning it up.I'm a serious diy guy and not a professional machinist so I'm not using this vise on a mill of any kind. I'm adding it to my big floor drill press to drill metals, plastics, woods, etc (I'm not using my drill press as a mill either, as it's not designed for side to side loading and don't recommend doing it).Overall this is a well machined heavy vise that should last forever if taken care of. I highly recommend it to a do it yourself person, not sure if it would fit the bill for a professional machinist or not. Rating it I deducted 1 star because of the amount of effort needed to be put into it. Four uploaded photos are attached. Hope this review helps you out.

I did a lot of research and looking around before I settled on this particular vise. I tend to put a lot of credit into the reviews that others write about their experience with products that I am interested in. I start with the star ratings and the number of reviews a product has received before moving on to the written reviews. True... this vise didn't have as many reviews as I typically like to see but I checked it out none the less.When I first opened the package the first thing that I noticed and thought was kind of odd was the fact that they only put packing material on the top side and and did nothing to protect the all so important bottom of the vise. There was no apparent damage but certainly something they should consider going forward. I will give it a closer inspection to ensure there is no damage and for flatness before i secure it to my mill.Like others have said, this thing is a lot bigger than I expected, but since I have a full size mill that won't be a problem. If you have one of the bench top mills the size and weight of this vise could be an issue for you. The next thing I noticed is what I thought was perhaps a milled test block that had been accidentally left in the jaws. After I attached the handle and started cranking the jaws open to remove the block I realized that the block was the jaw when I saw the seam start to open. I clamped the jaws closed again and the seam vanished. The jaw faces are perfectly (as far as the human eye can see) machined.I have not yet attached it to my mill for a test run but I have no doubt that it will provide my desired outcome. Unless something unexpected and catastrophic happens when I put it in operation, and I seriously doubt that will happen, I would absolutely recommend this product.I am certain that one can find a much more precise vise, but for the home shop and at this price I think this is a very good buy.

I bought the 4” and this little guy punches way above its price point. Packing grease cleaned up easily. I actually had to mount it twice. It comes with slot keys that were too wide for my mill table slots. So I mounted and trued it up. Then milled off .020” off each side of the keys. ( only the potion that’s in the slots). I removed the vise and installed the keys. It fit the slots perfect.I then reinstalled it again. I was able to dial it in to less than .0002” runout side to side. I then milled a slot in a scope base. This vise held the part secure and the slot came out perfect.I highly recommend this vise. I’m using it on Grizzly G0759 bench mill.

I wouldn't trust it on a CNC machining center, but it works very well on a bench
