The Starrett 117E center punch with round shank is 5" long and has a 1/4" (6.5 mm) diameter tapered point. The punch is made from hardened and tempered steel, which provides wear resistance and strength. The round shank is knurled for grip.
Center punches make small dimple marks in a workpiece to help guide a drill bit. Manual center punches have a metal shank with a point and are typically tapped with a ball-peen hammer to mark the material. Automatic center 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.

Love the knurled grip. Professional machinist grade tool at a very reasonable price!

Starrett hasn't disappointed me yet when it comes to tool quality- I've had this punch for a bit now and punched well over 200 center marks in stainless steel, and even more in carbon, and I've yet to have to sharpen it. A bit expensive for a single punch, but if it's on sale I highly recommend it.

Fantastic center punch. Best I’ve ever used by a long shot. For years I bought the cheapest tools and I’m finding that they were a waste. Everything I’ve had that was Starrett is still doing great. This punch finds my x easily and stays sharp.

Nice finish, hardened as needed. Center punch used to mark drilling pattern on marine parts.

Me siento estafado pues dice la descripción que es un puntero automático y es un granete normal para golpear con el martillo, aunque se ve de buena calidad
