Starrett 51283 Center Punch 3/16 Inch Steel Knurled

Product Description

The STARRETT 51283 is a center punch designed for accurate layout work in metal fabrication, HVAC, plumbing, and electrical trade applications. It creates a precise starter dimple for drill bits, preventing walking on hard surfaces. The punch is machined from steel and measures 3/16 inch in tip size with an overall length of 4.5 inches. The knurled grip provides secure hand control during use. This tool is a standard hand-drive punch struck with a hammer or mallet and is suited for both shop and field use by technicians across multiple trades.

The STARRETT 51283 is used wherever accurate hole starting is required on metal, sheet stock, or similar hard materials. Typical applications include marking pilot points on HVAC sheet metal panels, plumbing brackets, electrical enclosures, and structural steel. The compact 4.5-inch overall length makes it manageable in tight work areas. It is appropriate for residential and light commercial service work as well as fabrication shop environments.

Key Features

• 3/16 inch punch tip for precise center-marking on hard materials
• 4.5 inch overall length fits comfortably in a standard tool pouch
• Knurled grip reduces slippage during hammer strikes

Compatibility

Designed as a general-purpose hand-drive center punch suitable for use on steel, aluminum, and similar hard materials in trade and fabrication applications.

Installation Notes

Center punches are used by hand with a standard ball-peen or machinist hammer. Position the tip on the marked layout point, hold the punch perpendicular to the work surface, and strike the head firmly with a single controlled blow. No power tools or specialized equipment are required. Keep the punch tip dressed and free of mushrooming on the struck end to prevent material from spalling during use.
