Starrett 51282 Center Punch 5/32 in Steel Knurled Grip

Product Description

The STARRETT 51282 is a center punch designed for accurate dimpling of metal workpieces prior to drilling. The punch body is machined from steel and features a knurled grip section for positive hand control during use. At 4.25 inches overall length and a 5/32 inch punch diameter, this tool is sized for general-purpose layout and transfer work on steel, aluminum, and similar materials. Machinists, pipefitters, and fabricators use center punches like this one to establish drill starting points and prevent bit walking on hard surfaces.

This center punch suits bench work and field layout tasks in machine shops, fabrication facilities, and mechanical service environments. The 5/32 inch tip size is appropriate for marking centers on standard fastener hole layouts and general metalworking applications. The knurled grip allows controlled single-hand strikes with a ball-peen or cross-peen hammer. Its compact 4.25 inch length fits comfortably in a standard tool pouch or apron pocket.

Installation Notes

Center punches are hand tools used by machinists, fabricators, and mechanical tradespeople for layout work. Position the tip at the intended drill center, hold the punch vertically, and strike the top once with a hammer to create a clean dimple. Wear appropriate eye protection when striking. No power tools or code compliance requirements apply to hand punch use.
