2 Pack Automatic Center Punch, Pamiso 5.1 Inch Spring Loaded Drill Punch Tool,Brass Window Spring Punch Tool, Fixed Point & Car Window Glasses Break

I am a career firefighter and I can say this tool is very useful and works well. At one point the tool stopped “punching” after two years of having it. Many other people experience this as well. Except it is very easy to fix. You just re feed the puncher/spring through the hole of the sphere piece. Hard to explain but you have to hold the puncher spring through the hole, then grab the actual puncher tip and push down on the spring piece and then while holding it through the hole, re screw the cap back on. Can be a little bit of a pain, but is very easy to fix using common sense. Other than that, very useful tool for the price.

A versatile and reliable tool. Let me share how I use this tool for what I do. I am a Government Maintenance Painter at one of our Military Bases. I do repairs in temporary housing units that our soldiers occupy before being assigned to a battle group. Any damage to ceiling or walls or water damage from bathrooms or sinks, we mitigate those. This tool is mostly used to mark pilot holes before drilling or screwing fasteners into Wallboard, Wood, Metal or Concrete. It's one of those tools we use constantly from job to job. It is a very reliable tool and it is well made. The pricing is perfect. I recently purchased a set and gifted one for my co-worker who never had one. Now he uses it all the time. I, wholeheartedly recommend this tool to be purchased. It is a worthy investment. Finally, this tool can also be used to break glass. I would keep one in your cars glove compartment for safety if God forbid an accident happens and your car is submerged. You will be able to get out to safety. Give this product a try. Well worth it if you are in the trades/ contracting business.

These seem to be made a little cheaply. They don’t depress all the way and you have to press them down a couple times to get that “punch” press again otherwise they will still do what they’re supposed to do though!

Good works perfectly

Great product.

This is the same Glass Breaker Punch Tool that I was trained with. They do work effectively. I did have step by step instructions and safety precautions before Amazon changed my answer wording, I was very specific in my first response, this is my re-attempt. First thing's first, you'll want a pair of thick sleeves and gloves (preferably and importantly a pair of Firefighter Safety Gloves)., secondly you'll want (proper training as to how to use this tool). To use this tool be sure that you are using it away from any person's harms way (including patients, bystanders, and fellow Extricators). Only use on proper glass. (vehicles are designed with a safety glass, and this tool is commonly preferred to be used on side windows due to many windshields being laminated, big, and require proper training of removal.) If you are inexperienced, please seek assistance from someone certified in Extraction Training. In order to use this tool (with gloves), place one hand flat vertically in front of the desired hand to push with. And apply the tip of the glass breaker (preferably) in the desired (lower corner) of the window. Note: (It does not take much force) Note: safety glass is designed to uphold shock force in the centers of itself to prevent shattering. If you are unsure how to use this tool, or have never been trained with one, seek assistance from a Trained and Certified Extrication Professional. Keep out of reach of children, and those who are not authorized to use this tool. Be very careful ,cautious, and responsible when using. Thank you. Request to Amazon: Do not leave out my safety instructions this time. I am very specific on my wording for public safety.

One of 4 worked out of the package. Even if you tinker with them hit or miss every time. Junk

PAMISO spring loaded punch does work, and helped me with making wall holes for accurate drilling. But as other reviewers mentioned, yes, it does tend to come apart (wiggle loose) after a few uses. However, easy to re-attach the few parts. Shipped 2-pack means that I keep one in my car driver's door, for emergency use whenever needed.
