However, it’s supposed to be versatile. That means suitable for wood and aluminum as well. The adjustable impact force will allow you to use it for anything. You just have to unscrew out the knurled end grip to reduce and screw in again to maximize the force. But, many people said it’s useless. The force remains the same; too strong for a soft surface.

As we could see from the official page, the highest force it can provide is 250 N while the lowest is 180 N. For this range, it’s supposed to be able to create a strong mark on structural steel. We found it work on aluminum, mild steel, stainless, and steel. On the other hand, it’s not reliable to punch HSLA steel.

3. Fowler 52-500-290-0 Heavy Duty Automatic Center Punch

This Fowler is another heavy-duty automatic center punch that deserves to share with you. Amazingly, its overall length is 6 inch which is the longest one on this page. Along with that, the diameter shank is fairly fat 10/16 inch (0.625inch).

Aside from that, the piercing bit, two springs inside the body, and an internal small hammer are made of hardened steel. While the outer body is made of steel. All of that construction would make it feel solid in your grip. Additionally, like other high-quality center punch, you could replace the bit for replacement and other purposes.

4. Spring Tools 28R45-1 High-Speed Steel Center Punch

When the majority of automatic center punch relies on the spring mechanism inside the body, this one applies the same spring but no pressure is needed. The spring mechanism is very simple. And what just needs to do is pull up the spring and release. When the spring turns back to its initial position, the potential energy from the extending spring becomes the force to punch the surface you are going to dimple. This tool allows you to create dimples much easier, more fun, and accurate.

The Spring Tools 28R45-1 was specifically crafted to mark extremely solid materials. The tip is smooth enough and can be sharpened without losing rc65 hardness. Its hammerless action ability ensures accuracy and precision control to only give excellent results. The striking force for this can be measured at a whopping 3,500 pounds.



  • Burst power (High force)
  • Easy to use
  • Simple working mechanism

5. Starrett 18AA Small Dimple Automatic Center Punch

Starrett 18AA is considered as the smallest automatic center punch. Its body length is only 4 inch but the 7/16 inch thickness remains solid. In spite of small size, it’s remarkably reliable to finish works that require highly precise and tiny indentation.

Compared to 18C, Starret 18AA only generates a small dimple. However, that is the value. If you want to dimple jewelry stone or the components, this will go perfect for you. The probe bit which is hardened tempered steel will be great for any surface. Also, it’s replaceable. So when you need to make a smaller dimple, you could sharpen it. Similarly, if it becomes dull, you can change it.

The benefit of using Starrett 18AA is really obvious. It acts softly and requires relatively small power to depress. As a result, the narrow force it generates will not deflect the area around the marks when there is no base behind. Especially when you are working with a thin metal sheet, this lovely tool will not ruin the even surface.

In case you have to use it for a tough job, you could still use it but you have to punch a few times until you get the appropriate depth and width that you want. Nevertheless, we don’t recommend to do that.

This cool stuff is also ideal to be one of your car emergency toolkits. Because of its compact size and lightweight, it will fit whether saved in your vehicle storage box or travel bag. Moreover, your kids would easily use it as it doesn’t need too much power to activate the punch.



  • Great to prepare a dent for jewelry drilling purpose
  • For light purposes
  • Kids emergency punch


  • Not for heavy-duty work

6. Lisle 30280 Pocket Clip Automatic Center Punch

Lisle 30280 is a slim, pencil-like design, lightweight, and pocket clip built-in automatic center punch. It also has a sharp punching bit which is good to make accurately dimple marks. Moreover, it’s also made from hardened steel which means able to use for many applications.

However, this one is actually a light-duty center punch. It works pretty well when tempting to mark on hard metals but only fires a tiny dimple. You might want a hammer and center punch again to widen the dimple. We also encourage you to use it not too frequently.

The downside may come from the production quality. If you have bought it, our suggestion is to disassemble and lubricate the spring and other components before using it.

Overall, Lisle 30280 is no reason to give it a try. If you are lucky enough, you’ll get the money shot for your light works. Many people have used it and find it last for years. In addition, it has the possibility to replace the punching tip. If it wears, you could buy the new one Lisle 30290.



  • Durable
  • Affordable
  • Lightweight, slim, pocket clip

7. General Tools 89 Stainless Steel Automatic Center Punch

Another auto center punch on the list that you have to consider is General Tools 89. What makes it great is the hardened steel bit which is good to confidently hit hard metal such as steel. And the solid stainless steel material on the body is aimed to protect the tool from rusting.

It actually works and more accurate than the traditional way using a hammer and center punch. But the mark it produces on certain metal such as stainless steel is not really satisfying. You still need the hammer and center punch to enlarge the dimple in order to create a sufficient diameter for drilling. However, it will work well for soft metal or wood.

Does the size matter with you? It has 5.25 inch in length and 9/16 inch in thickness. You could estimate whether the dimple it generates will fit your drill bit or not. The dimple it creates is about 1.8mm (0.07 inch) in diameter. You could set up the impact by turning around the knurled grip end intuitively.

The drawback addresses the bit which seems not replaceable. You cannot sharpen it or substitute it with the new one in a case being dull. But the punching power is like the others which are adjustable.



  • Good to use for wood and soft metals


  • Not a replaceable bit

8. Starrett 819 Self-Centering Automatic Center Punch

It seems too many Starrett products reviewed here. Don’t get me wrong, folks! We just find their products useful and deserve to share. Starrett company really does manufacture excellent tools.

When installing the door hinge, you’ll have to mark the place where the screws will be drilled in. If the surface is metal, you’ll punch it to contrast the mark and easily guide the drill. The chance is you may not mark it right at the center. Plus, using the manual center punch makes things even get worse. The hinge ends up being installed inaccurately.

Imagine if you’ll have to install a fair number of hinges in a day. Using this Starrett 819 will be very effective and saves your time.

9. Neiko 02638A Automatic Center Punch for Wood

Neiko 02638A features a punching bit made from S2 steel. This steel consists of extra vanadium and manganese. These will definitely add hardness and wear, plus at the same time minimize brittleness. However, despite it’s okay to use for metal such as mild steel, we prefer to use it for wood. If you keep going, you might find it less powerful and end up repeating several punches to get a bigger and deeper dimple.

For this kind of price point, finding the bit made from S2 steel is considerably very affordable. You certainly understand not to expect it’s from carbide. Hence, if you are going to use this for wood, that would be more than decent. Especially if there are loads of dimples need to be punched, the plastic red ball handle which is ergonomic in the palm of your hand will allow you to make a lot of dimples without having hurt feeling to your hand’s palm.

Moreover, this item comes with a 5-inch total body length. So, it’s neither too big nor too small. The body shank is coated with chrome which is good to counter corrosion. Aside from that, the striking force is adjustable by either screw or unscrewing the red ball.

How Does An Automatic Center Punch Work?

Before the invention of the automatic center punch, people call it just the center punch. To use it, you need a hammer to punch it in order to make tiny dimples.

Commonly, an automatic center punch consists of these parts: 2 springs, 1 mini hammer, and 1 punching bit. However, the spring and punching bit are the most highlighted. The spring determines how strong the striking force, whereas the punching bit determines how able it is to penetrates the surface being punched.

People then created a simpler one. The force from the hammer was substituted. The tool then employs the spring because it can store energy. In such a way, when you push the punch, the mechanism happens, and at a certain condition, the spring will release the force to the pin and it makes a hole.

The force released by the pin is like the force done with the hammer. Therefore, this tool can be used to break the car window in case something bad happens. So, you don’t need to carry around your hammer anymore.
