(663) Master Screws Up Yet AGAIN (Thanks Deolslyfox!)

My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. That hole won’t do shit. Because of a simple thing called surface tension. The water will just coat the spring anyway.
    Yes, it will evaporate over time. But when it can flow in at the top, it can evaporate out too.

  2. I don't see that the hole makes the lock any weaker than it already was. A drill is usually not the tool of choice for a thief. Marking the location of the screw head doesn't make it easier for him to use bolt cutters or an angle grinder.

  3. I thought you were going to use a hardened pick to back out the screw!
    Push the pick in against the screw-head, then lever it to the side.
    Repeat for a metric eternity…
    Sure it would be tedious, but the defeat would not require drilling anything.

  4. well.. no thief will bring a drill for such… it is more convenient to bring a bolt cutter which will work too and can cut that shit in 2 sec.

  5. master lock sucks…their standard silver/blue padlocks only have a few key designs. Our company has a several of them that work with the same key. Well one day I got locked out of a site that had the same style of lock so for the hell of it I tried my key and guess what? it opened! I work for a mechanical contractor and the lock on the site to the gate was owned by the general contractor. So anyone with a key to that gate can get into our job boxes and vice versa…pretty sorry excuse for security.

  6. Master Lock are sold in a lot of store in Italy. And people think they are very good locks……. Many thanks Bill for your explanation.

  7. That is a valid point. But if you are going to drill a lock with such a big bit (as showed by the drilled example piece) then why have any caution at all? Why not drill into every lock? Why not cut the lock? You can do this with any lock and not with such a fine bit.

  8. A lock is just to keep a honest person honest. Not to keep thiefs out, a thief would just use bolt cutters or batter powered grinder.

  9. The question I have is being Masterlock made a bulls-eye on the newer locks. If you were to drill out the older lock in the same area, will it give you the same result?

  10. I've been watching a few of your videos about locks, & keep thinking that the locks do what they were meant to do. That is to say they keep the normal person out of the locked item. I would say, 'keep the honest people honest' but I don't really believer there are many of honest people. It's just that the normal people don't want to take the time or risk to steal, & rightly so. Now with this lock on this video, your not quite being fair, for if you wanted to get in this lock you could just use bolt cutters, or a cut off wheel, or what have you, to be in the locked compartment quicker than drilling a hole. So we must say that 'Master' lock did not really weaken the lock, at most just made another way to compromise it. Another way true, but does it really make it less safe, in that the drilling it out would still be harder than the other ways. 🙂
    Thanks for the videos I do find them real interesting, Singed an 'honest' person.

  11. I know this is an older video, but I'd like to say that a lot of these american locks are used in manufactures to lock out machinery for maintenance. But if master sells this for protection of consumers' goods, well that's a cheap move on them…

  12. Well, those are aluminum bodies correct? So if you were to drill in the same location, even without the hole, couldn't you get in?

  13. Well if you 're gonna destroy it, wouldn't it be easier to cut it with a bolt cutter. It would be more quiet and faster.
