## Description

Product Description The Starrett 18C heavy-duty automatic centre punch with adjustable stroke is 5-1/4" long with a 11/16" (17 mm) diameter for creating a starter dimple without the need for a hammer. This heavy-duty model is capable of striking a heavier blow than the Starrett 18A and 18AA automatic centre punches. It has an adjustable stroke, which can be set by turning the knurled cap and is regulated by spring tension for uniform dimple size at every setting. The punch is made from hardened and tempered steel components that provide wear resistance and strength. It has a round handle that is knurled for grip. The point can be removed for replacement or sharpening. Centre punches make small dimple marks in a workpiece to help guide a drill bit. Manual centre punches have a metal shank with a point and are typically tapped with a ball-peen hammer to mark the material. Automatic centre punches have an internal spring mechanism that enables them to mark the material without using a hammer, leaving one hand free for steadying the work. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment and saw blade products. The company, founded in 1880, is headquartered in Athol, MA. Box Contains 1 x Automatic Centre Punch

Review: Good but needs a firm push - Well made and powerful - needs a strong push to activate but the indentation produced is good. Much more controllable and accurate than a hammer and punch.
Review: Very strong & powerful. Great for what it's designed to do. May be overkill for household DIY - Giving it 5 stars because it's great at that it's designed to do and is of great build quality. Speeds up the making of screw holes very much over more manual tools. In my personal case of needing such a tool for internal, mostly wood screws, it's overkill -- too powerful and therefore a little bit difficult to use... you need to exert quite a bit of power to get it to punch the hole. A lighter unit would be more suitable for household DIY but I was just starting out and obviously couldn't try out the product beforehand but none of this is to fault the product itself in any way.

## Questions & Answers

**Q: can this punch/make a mark on hard steel that's enough for drilling to stay in place when drilling through it? how strong is it to push down for it?**
A: It all depends on how hard the other steel is.  The punch is hard relative to most everyday steels but not against case hardened machine parts.  Use a short stub drill of cobalt in a rigid setup.

**Q: are these easy and not too stiff to press down? i want to mark a small 6mm motor rod/shaft and need it to be easy to press down.**
A: i found it easy but im used to it, it is expensive for what it but should last years, the only problem with marking on a thin round rod is slip when pressing down for the punch , if you can file a tiny flat spot onto the  rod with a file it will not slip

### ⭐⭐⭐⭐⭐ A strong punch!
*by S***E on 15 October 2024*

I bought two of these from Amazon warehouse at a very good price. I found that both punches failed to trigger despite pushing with considerable force, obviously the reason they were returned! Amazon warehouse clearly doesn’t “fix” or test them! They arrived in original but re sealed Starrett packaging. So I was happy they are genuine Starrett products. Being Starrett they are obviously very well machined to high tolerances from high quality materials, so the problem is with the main spring. The design allows for adjustment of the “trigger” pressure by screwing the cap in or out. At maximum (softest) adjustment only one would “fire”. I disassembled them checked all the components were present and measured the spring lengths. Both springs were very stiff and too long for the contained length when unconfined. New springs which had never been compressed. Using water pump pliers (parallel jaws) I gently compressed the springs by around the designed length of travel (cap length) and released, 3 times. This conditions the spring to the required travel. I reassembled both punches and voila! Both work perfectly. A simple fix. Time to unpack, assess and fix less than 10min. Clearly given the number of customer complaints around their automatic punches on Amazon Starrett, despite being one of the premier tool brands, are failing to factory condition their spring punches. 😠 So, it appears that it is pot luck whether a new punch works strait out the box so you might as well try an Amazon warehouse one, if needed it’s a very simple fix and save ££.
