Starrett 51285 Center Punch Set 7 Piece Steel Square Shank

Product Description

The STARRETT 51285 is a 7-piece center punch set designed for accurately marking drill-start points on metal and other hard materials. Each punch features a square shank for positive grip in a hand or bench vise, preventing rolling on the work surface. The set covers a size range from 0.0625 inches to 0.25 inches, giving technicians and tradespeople a full spread of punch diameters for varied hole-start applications. Punches are machined from steel for durability under repeated hammer strikes. The complete set stores in an included round plastic container, keeping pieces organized and protected on the job or in a toolbox.

This set is suited for metalworking, HVAC fabrication, plumbing rough-in layout, and general mechanical trade applications where precise drill location is required. Individual punch lengths range from 3.0 inches up to 5.0 inches, accommodating both fine detail work and heavier layout tasks. The seven included sizes cover the most common punch diameters used in light to medium trade fabrication and service work.

Installation Notes

Center punches are used by hand with a ball-peen or machinist hammer. Place the punch tip on the marked layout point, hold perpendicular to the work surface, and strike squarely with the hammer. Wear appropriate eye protection when striking hardened tools. Inspect punch tips regularly for mushrooming and dress or replace as needed to maintain marking accuracy.
