Run me through the anti-drilling features locks may possess?

[totse]

Thanks.

drillbreaker armor such as is found on american padlocks,

hardened drill breaker pins such as found in medeco and many other hi sec locks.

a drill cutting into brass proceeds blithely along until it hits one of these pins, then the force of the drill is deflected so that the cut rams off center and into soft brass until its just to jammed, then the drill breaks and you have a banjaxed lock with a sharp piece of drill sticking out of it and jammed so tight that you might not be able to jerk it out with a pliers,

medeco also uses little half moon inserts to protect the sidebar and the shearline, if you hit one of these, (im making this up
I have never drilled one or hit the moons) it is likely to jam the core.

these little things make reassembly of a medeco more interesting, but petroleum jelly is the way to hold them in place, use only a small amount.

Medeco and other high security locks that are rim mounted (two long mounting screws) often come with two ball bearings that are supposed to be in the holes tapped in the brass for these screws. Many medecos are mounted without these bearings, so a template to locate these holes will allow a drill to unscrew them from the outside.
if the balls are falling out, once again, petroleum jelly can solve this.
when a drill hits the hardened ball bearings, (all ball bearings are hard) the drill may happily start spinning freely until it slips sideways and then you have the broken drill bit sticking sticking out and firmly jammed.

some dead bolts will have a roller bearing inside to make anyone with a sawzall have an interesting time, there are also ceramic inserts in some bolts that will dull a saw very quickly.

thats all Ive got for now.

Please post your actual question in your post body versus just "Thanks" after asking the question in the subject line. I have people at work who will email me their entire question in the subject line and leave a blank email body.. :shakes head:

At least you say thanks though, so all hope isn't lost.

The original poster's intentions may be fine, but should we really be providing info on DE for high-security locks to people with single-digit post counts (and in the public forums)? Just doesn't feel right to me.

Yeah, I was under the impression that destructive entry is only allowed in the advanced forums. But maybe I'm wrong, seeing as how Mr. Squelchy (mod) has chimed in here already and not moved the thread.

Poster may be looking for a secure lock for their residence or business, not enough information given to make a move to Advanced.

Nice to see you back on the forum!

Thanks raimundo.

I take it that anti-drilling features are almost exclusively the domain of high-security locks?

If it makes you happy, I will in future. I didn't because, well, I had no further information to add and I didn't want to seem repetitive. :p

Ray, you drop these little nuggets of useful information every time you start typing. Ever consider writing a book?

about the ball bearings, I meant to get that out so that people here who may be installing a medeco will not find them in the parts and just throw them out which is the problem.

I have a couple of movie scripts from a decade or two ago, but never got far in writing a novel. but Sue grafton has mentioned me in the front page of a couple of her books, L and O I believe.

Of course you me a tech manual, well there are large gaps in my knowlege, such as current automotive locksmithing and such,

I use the forum to learn just like everyone else here.

Another interesting and less messy nugget on how to keep those pesky Medeco deadbolt security ball bearings in place is to break them out of the plastic baggie they are in by tearing off a small piece of the baggie with the ball bearing in it which you shove into the screw hole with the ball bearing... It stays in, no greasy petroleum jelly needed... Raimundo's idea only using white lithium grease instead of petroleum jelly is the preferred method of dealing with the ball bearing locking parts in serviceable padlocks which have a tendency to want to fall out or move around on their own as you handle the lock to service it...
