This Starrett center punch set has exactly what you need for precise marking in the workshop. You get seven different punches with tapered points ranging from the tiny 1/16\ all the way up to 1/4\ - specifically 1/16\, 5/64\, 3/32\, 1/8\, 5/32\, 3/16\, and 1/4\ diameters. Each punch is built to last with tempered steel shanks for strength and hardened steel points that resist wear through years of use. The square shank design is genius - it keeps them from rolling away when you set them down on your workbench, and the knurled grip gives you solid control even when your hands are oily or you're wearing gloves. These make perfect little dimple marks to guide your drill bits exactly where you want them, preventing that annoying walking that ruins precision work. They come in a sturdy red plastic case that keeps them organized and protected when not in use. Starrett has been making quality tools since 1880, and this set shows why they're still the go-to brand for professionals who need their tools to work right every single time.
