Starrett 51279 Center Punch 5/64 Inch Knurled Steel

Product Description

The STARRETT 51279 is a center punch designed for accurately marking drill start points on metal and other hard materials. At 3.5 inches overall length, the punch provides a compact, controlled feel suited to layout and fabrication work. The 5/64 inch punch tip delivers a precise indentation point, reducing drill bit walk on ferrous and non-ferrous stock. The knurled grip adds traction during use, particularly in shop environments where hands may be oily or gloved. This tool is used by machinists, pipefitters, electricians, and general trade mechanics who require repeatable punch placement during fabrication or field service.

The STARRETT 51279 is a compact center punch suited to light metal layout work, conduit preparation, and general-purpose marking tasks. Its small punch size makes it appropriate for thin-gauge sheet metal, bracket work, and tight-clearance applications where a full-size punch would be difficult to place accurately. At under 4 inches overall length, it fits easily in a tool pouch or apron pocket for field use.

Compatibility

Designed as a general-purpose center punch for use across common trade and fabrication applications involving metal layout and drill point marking.

Installation Notes

Center punches are hand tools used by machinists, electricians, pipefitters, and general tradespeople. No power source is required. Strike the punch with a ball-peen or machinist hammer using controlled force to create a clean indentation. Inspect the punch tip regularly for mushrooming or deformation, and replace if the tip is damaged to avoid inaccurate marks.
