Starrett 51183 Pin Punch 1/4 Inch 8 Inch Oal Steel

Product Description

The STARRETT 51183 is a 1/4-inch pin punch designed for driving out pins, keys, and fasteners in machinery, assemblies, and mechanical equipment. Machined from steel with a knurled grip for secure hand control, this punch measures 8 inches in overall length with a 3-inch tip length. The 1/4-inch tip diameter suits common pin and key sizes found in shafts, linkages, and gear assemblies. It is used by machinists, millwrights, mechanics, and maintenance technicians who need a reliable, straight-driving punch for disassembly work.

The STARRETT 51183 is suited for general maintenance and repair applications in shops, plants, and field service environments. It handles removal of roll pins, taper pins, dowel pins, and drive keys in a wide range of mechanical assemblies. The 8-inch overall length gives sufficient reach for recessed fasteners while keeping the tool balanced for hammer-driven use. This punch is appropriate for both light bench work and heavier machine disassembly tasks.

Installation Notes

This punch is installed by machinists, mechanics, and maintenance technicians using a ball-peen or mechanics hammer. Always wear appropriate eye protection when driving punches, as metal fragments or pin shrapnel can be ejected. Ensure the workpiece is secured before striking. Do not use this punch as a chisel or pry tool, as lateral force can damage the tip or cause the punch to slip.
