There are a lot of articles and videos on the Internet about using an automatic center punch to quickly break tempered glass in side windows of a vehicle as a means to exit a vehicle if it is not possible to open a door or window of a vehicle.

There are a lot of articles and videos on the Internet about using an automatic center punch to quickly break tempered glass in side windows of a vehicle as a means to exit a vehicle if it is not possible to open a door or window of a vehicle.
An automatic center punch can be used to break tempered glass by pressing the point of the center punch against the face of tempered glass until the spring in the center punch compresses and releases against the glass. Care should be used to avoid getting cut from glass shards when breaking tempered glass.
This automatic center punch is similar to the automatic center punches marketed and sold specifically for breaking tempered glass. This tool has a hardened punch and a precision and sharp point on the punch for precisely marking center holes on most materials including metals.
The punches in automatic center punches marketed and sold specifically for breaking tempered glass likely are not hardened enough to be used to reliably mark center holes on all types of metals and may not have a point as precision and sharp on the punch since those features are not required for breaking tempered glass.

Answer: 
Would not recommend striking an automatic center punch with a hammer because that will shorten the life of an automatic center punch and will also likely destroy the automatic spring mechanism inside of an automatic center punch that transfers force to the center pin of the punch.
It is not worth destroying an automatic center punch unless it is not going to be used as an automatic center punch Read More
Would not recommend striking an automatic center punch with a hammer because that will shorten the life of an automatic center punch and will also likely destroy the automatic spring mechanism inside of an automatic center punch that transfers force to the center pin of the punch.
It is not worth destroying an automatic center punch unless it is not going to be used as an automatic center punch anymore.
Striking an automatic center punch with a hammer will not make a better indentation since the force of the punch is controlled by the stroke length of a spring inside of the punch.
Home Depot and other suppliers offer a 3 piece manual center punch set that requires a being struck with a hammer. It is cheaper to use a manual center punch with a hammer then it is to destroy an automatic center punch with using a hammer.

Can also use a large steel nail such as a #10 as a manual center punch in a pinch a few times depending on the hardness of the material being marked until the point of the nail is no longer useable. Read Less

Rated 3.9 out of 5 by 14 reviewers.
Rated 3.0 out of 5.0 by Not very precise Only use this punch if accuracy isn't very important. The punch pin is loose in the case and the point is blunt. I sharpened mine to stay on the point when actuated. I have two of these and they are both the same. It will work very well for screw starter punch's on metal building construction using self tapping screws. I sharpened one of these for a punch to start drill bits for hinge screws. Sharpening the point allows the punch to stay in the center of the hinge hole and keeps your bits from wondering when you pre-drill for your screw. December 11, 2014
Rated 4.0 out of 5.0 by Good automatic center punch Bought this automatic center punch for use when drilling holes in steel to provide a reliable starting point indentation with the center punch to prevent small diameter pilot drill bits from wandering while drilling pilot or starting holes in steel and other hard materials. This punch works reliably as the manufacturer advertises with being able to operate the punch with one hand without requiring a hammer which is convenient when one hand is required to hold a work piece. This punch is easy to use and has a small diameter point which makes it easier to position on center marks on a work piece while providing an adequate indentation on a work piece to prevent small diameter pilot drill bits from wandering while drilling. It takes a little effort to use this punch repeatedly because the punch has to be pressed down with enough force to compress and release an internal spring that releases the pin of the punch into the work piece. The force that the center pin of the punch strikes a work piece is adjustable through varying the spring stroke release length of the punch through rotating an adjustment on the top of the punch.

Rated 4.0 out of 5.0 by it has been improved the last general I had had an aluminum casing and would not operate most of the time. This one is all steel and fires every time. The equivalent Starrett is 40+ dollars. Buy the general. June 18, 2015
Rated 4.0 out of 5.0 by perfect solution for the intended job The punch easily marked the layout for installing door hardware on cabinet doors. I like using a punch because it keeps the drill bit from drifting. February 25, 2015
Rated 5.0 out of 5.0 by Great Used it a numerous times. Works great. Works great with all kinds of wood. February 25, 2015
Rated 4.0 out of 5.0 by Good spring loaded center punch Springs and construction better than the one available at Harbor Freight March 1, 2015
Rated 5.0 out of 5.0 by Hard Worker Ease of use is pretty straight forward, but it's tough and has kept moving through a lot of hard use. I would definitely buy this one again. October 21, 2014
Rated 1.0 out of 5.0 by Not enough punch I bought a cheap center punch at different store. It worked ok until it stopped working all the time. I thought that if I got an adjustable one that was more expensive it would be better. Man was I wrong this center punch was the worst yet, I can barely even tell where the mark is after I use it. Unless your are center punching wood, DO NOT BUY. August 17, 2014
