Starrett 50484 Center Punch 3/32 Inch Knurled Grip Steel

Product Description

The STARRETT 50484 is a center punch designed for accurate starting-point marking on metal, wood, and other hard materials before drilling. Machined from steel with a knurled grip, this punch gives technicians and tradespeople a reliable hold during strike operations. The 3/32-inch punch size suits precise layout work where a clean, tight indentation is required to keep a drill bit on center. At 4 inches overall length, it fits naturally in hand and delivers controlled force from a standard ball-peen or utility hammer. This tool is a standard item in HVAC, plumbing, and electrical service kits where field drilling and metal layout are routine tasks.

The STARRETT 50484 is suited for residential and light commercial service applications. It is commonly used by HVAC technicians drilling sheet metal for fasteners or knockouts, by plumbers marking pipe hangers and bracket locations, and by electricians laying out enclosure penetrations. The 4-inch overall length is appropriate for general bench and field use without becoming unwieldy in tight spaces.

Installation Notes

Center punches are used by hand with a hammer — no power tools or special codes apply. Position the punch tip at the marked center point, hold firmly with the knurled grip, and strike squarely with a ball-peen or utility hammer. Wear appropriate eye protection when striking hardened tools on metal surfaces. Keep the punch tip properly dressed; a mushroomed head or worn tip reduces accuracy and increases the risk of the tool slipping under strike.
