Yost ADI-4 4-Inch 130,000 PSI Austempered Ductile Iron Bench Vise with 360-Degree Swivel Base

Guillaume Lambany: Haven't tried many brands of vise but, it is a very smooth vise. The set screws are quite loose tho, might have to loctite-blue them for the setting not to change over time. Jaws were slightly offset when I received the vise but, easily adjusted with the play there was in the two screws that holds the jaws. Now its aligned perfectly. Very happy to be upgrading my previous 4 inch, mastercraft vise, which someone else at work bought, and it was garbage. I think this will make my work much, much easier from now on. Entirely satisfied with the purchase, this seems like a high quality vise to me.

JUAN ORTIZ: No sabía si darle las 4 o 5 estrella al producto ya que el tornillo que se envió es ADI no es FSV, en si el ADI es un modelo más nuevo, costoso y resistente, pero como tal no es acero forjado, me quedaré con el tornillo por qué está muy bien, el hecho de que no de las 5 estrellas es que como tal no es el producto que dice, aunque sea algo mejor, no es lo que dice.

Amazon Customer: I've been using this vice in my work room for about a year now, after shattering my old cheap cast one. So far, it has taken all the abuse I have thrown at it, and been worth every penny. I was extremely impressed with the packaging, mounting instructions, and overall feel of the vice, right away. No broken English instructions, or cheap pot metal parts. It is well finished, no crude casting, or poor craftsmanship noticeable. My only complaint, if you can call it that, is that the pipe jaws aren't very spread out, so it allows round stock to move a bit when you push on it. That said, I barely use them, and the rest of the vice can't be beat for anywhere close to the price. I would definitely recommend a Yost vice to anyone who wants quality, but can't afford to spend $1000+ on a vice

Karson Penwarden: There is not much to dislike about this vise . the only reason I gave it 4 stars is when you have to swivel it in either direction you have to back the clamps way off in order for it to swivel smoothly but other than that it is a great vise you wont be disappointed.

V G: I received the ADI version, which is a direct replacement to their FSV line (which is now discontinued). I contacted the company and they were quick to respond to my question regarding the warranty, which the same as for the FSV series - lifetime warranty on the casting. Everything about this vise is solid. I disassembled it as soon as I got it to grease everything up again nicely.

The only negative thing I noticed is that the paint chips off very easily in places and you'll see a lot of paint flakes when you disassemble it. Not a big deal, just coat it with some grease.

Others have commented that the jaws did not line up on their units, but I had no issues with mine. Note that there are two black screws on the side which push against a small metal bar inside to adjust the play in the sliding section. Make sure to grease up the rails well and you can turn the screws almost all the way in to reduce the slop to close to zero.

Joseph: Phenomenal vise for an affordable price especially if you catch it on sale. I bought the Yost FSV-5 for my step-son for Christmas and I might have to pick another one up for my garage. Everything you read about the vise in the product description is accurate as far as I can tell. The replaceable jaws appear to be machined and mate up perfectly flush. The action is nice and smooth. The turret permits rotating the vise freely. Aside from all the wonderful features, I primarily chose this model because it's made with 90,000 PSI forged steel. For the price I paid I feel like I stole this beautiful chunk of steel. There's a great video review on YouTube for the 6" version if you want to see how tough these vises are and what they can handle. The 5" is smaller of course but I have no doubt it will hold up for years to come. Also, I prefer forged steel over the cast iron used on the lower priced vises. However, Yost does make ductile iron vises right here in the USA but they cost significantly more. The FSV-5 line are all made in Taiwan from what I understand. The other thing that makes this vise a real bargain is the lifetime warranty. One last thing, the red paint is a nice change from...

Chris Littlefield: Finally, at 64 years old, I have a great vise, in addition to my many earthly vices. I realize that sounds a bit dramatic, but I've put up with hardware store vises whose jaws never cared if they aligned and, regardless of the force you tried to apply to the swivel lock, with a little pressure, the vise would swivel. I ordered the Yost Vises 880-DI 8" Heavy Duty Reversible Bench Vise first and pretty much over shot the mark. Great looking vise but far too large and tall for my purposes. Fortunately for me, it was damaged (the shipping process actually damaged a vise) such that the bar used to tighten or loosen the vise was bent and would not slide back and forth at all. So I down-sized to this vise and I am pleased. It is the right size, jaws align at all angles, the mobile jaw does not wobble at all, and if it did, there is an adjustment to de-wobble. There are two rotation clamps and they latch very firmly. Finish work is excellent and what is not to dig about a red vise! I think this vise is an excellent value and will make an excellent heirloom because even if you are much younger than me, it is still going to outlive you!

Mr.Metalsmith: I don't always take the time to write reviews but now and again theres a tool or product that makes me feel like I need to give it the due process it deserves. This Vise is certainly one of them (obviously). It arrived within a week of ordering it, got free shipping and the packaging was wonderfully done, double boxed and padded inside, arrived in perfect condition. Beautifully accented and painted a bright crisp red that draws your attention inside of the shop. I love that the attachments are oxidized for longevity, it certainly has done the trick inside of this climate which does get relatively humid now and again. The performance of the unit is nonetheless outstanding than it's appearance and well thought packaging. It has great clamping force, the swivel base has no movement once pinched down with a relatively light touch, really doesn't take much to get it rigid enough for fixed & sturdy workstation. The anvil is well machined and of a nice covenant size for the overall construction of the unit. I applaud the innovation put into the design for adjusting the tolerances of the unit to adapt for normal wear and tear overtime. That's very nice. It's got a full lifetime...

William N: I went through decades of cheap made in China cast iron vices that are weak, sloppy, and prone to fracturing. I never actually had one crack on my but you know what, I wanted some quality. This one is made in Taiwan and is of solid forged steel. Yost is an old respected name. This is a real machinists vise. I overpaid for mine a bit have seen them as low as a hundred but still very happy. For a 4" vice the strength of this vice is incredible. I mounted mine over the lip of my workbench so I can clamp tall objects. So when the vice is closed it overhangs the edge of your bench. Don't quote me but I think the clamping strength of this Yost vice is about 8,000 pounds. It is easy, one finger operation. The first thing I did before ever using is was to remove the waxy, brown Cosmoline type shipping greast from all surfaces of the vice including the main screw underneath. Then I lubed the screw and all sliding surfaces with Magnalube G lube which in my opinion is the finest lubricant grease in existence. All moving or sliding parts were lubed and I also worked in a thin coat on the top anvil surface for corrosion resistance. I have had the vice for six months now and it is centerpiece...
