Starrett Co.), is based out of Athol, MA. Looks like it is a fine crafted tool that I will be passing on to my son some day. The tool itself is not stamped "Made in the USA", but is stamped with the company name and the model number. You can see the craftsmanship put into this tool. I think that you will be very happy with it. **Q: If i was only looking to purchase one size center punch wood this be a good size to go with?** A: This is the smallest of the Starrett punches. It works well on soft and thin metals as well as wood. 18c is larger and works better for harder metals and is also easier to hold. **Q: Will this work on tempered auto glass?** A: It will shatter tempered glass. **Q: Which center punch breaks Bullet proof** A: None break bullet proof glass because of how that glass is made and it thick glass hence the name “Bullet Proof”. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect automatic punch *by S***O on March 25, 2026* High quality, durable, easy to use, and does exactly what I need for a fair price. Ive used it on hardened steel, mild steel, aluminum, etc, never an issue. Knurling adds a lot of grip on it even when your hands are oily. Can't go wrong with Starrett. ### ⭐⭐⭐⭐⭐ High Quality Tool from Starrett *by S***U on February 27, 2026* I own and enjoy using a variety of Starrett combination squares but I should have gotten this center punch a long time ago. It works like a charm! ### ⭐⭐⭐⭐⭐ 5,056 TOTAL PUNCHES; DURABLE, RUGGED, USA QUALITY *by F***K on February 4, 2025* So let me tell you a story. I work in the automation industry for warehouses and mailing. I had to assemble 79 pulleys with flanges on both sides that needed to be pressed down and swaged. Unfortunately the tool they had does not work well at all and I had to resort to manually punching 8 points around the flange both sides to ensure it stayed properly and securely in place. That's 16 points per pulley x 79 = 1,264 hits x 3-4 hits per initial hit to ensure the material went over the flange to hold it in place. Thats a whopping total of roughly 5,056 total hits in a 8 hour shift. NOT ONCE did the punch seize up or give me any trouble. the tip still retains its sharp point and the punch still works smoothly and effortlessly compared to the junk one at my job they gave me originally that at every 3-4 presses it would seize up and not want to follow through. If this doesn't scream quality and durability then I don't know what does. Starrett know what they are doing and do it well. Fantastic tool, it won't let you down. ## Frequently Bought Together - Starrett Steel Automatic Center Punch with Adjustable Stroke - 5" (125mm) Length, 9/16" (14mm) Punch Diameter, Lightweight, Knurled Steel Handle - 18A - Starrett Steel Automatic Center Punch with Adjustable Stroke - 5-1/4" (130mm) Length, 11/16" (17mm) Punch Diameter, Lightweight, Knurled Steel Handle - 18C - Starrett Automatic Center Punch with Hardened Steel Metal - 100mm Length, 11mm Punch Diameter Tapered Point - 18AA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/31118051-steel-automatic-center-punch-with-adjustable-stroke-5-length-9](https://www.desertcart.com.ar/products/31118051-steel-automatic-center-punch-with-adjustable-stroke-5-length-9) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-19*
