Proto J471/2X1/4 Drive Pin Punch 1/4 Inch Steel

Product Description

The PROTO J471/2X1/4 is a drive pin punch designed for driving out pins, roll pins, and fasteners in mechanical assemblies. Constructed from steel, it delivers the durability needed for repeated impact use in shop, field, and industrial service environments. The punch head measures 1/4 inch in diameter with a tip length of 2-3/16 inches, giving technicians precise reach into tight clearances. The overall length of 6-3/4 inches provides adequate hand clearance from the hammer strike zone, reducing the risk of hand injuries during use. Machinists, millwrights, and equipment service technicians are the primary installers of this tool.

This drive pin punch is suited for use in maintenance, repair, and overhaul work across mechanical, industrial, and trade service applications. It is appropriate for removing or seating pins in gear assemblies, hinges, linkages, and similar mechanical components. The 1/4-inch punch size covers a common pin diameter found in a wide range of light to medium-duty equipment. The steel construction handles standard hammer and mallet strikes without deforming under typical service conditions.

Installation Notes

Drive pin punches are used by machinists, mechanics, and maintenance technicians. Always wear appropriate eye protection when striking a punch, as metal fragments and chips can be ejected. Use a ball-peen hammer or brass mallet appropriate to the task and ensure the workpiece is properly supported or secured before driving pins. Inspect the punch tip before use and remove from service if the tip is mushroomed or cracked.
