Proto J505/16 Starter Punch 1/8 Inch Steel

Product Description

The PROTO J505/16 is a starter punch designed for driving pins, bolts, and fasteners out of tight assemblies. Built from steel, it delivers the durability required for repeated impact use in heavy-duty shop and field environments. The punch measures 1/8 inch at the tip with an overall length of 5-1/8 inches, giving technicians adequate reach and control during use. Licensed tradespeople including mechanics, pipefitters, electricians, and HVAC technicians rely on starter punches like this one to initiate pin removal before finishing with a longer drift punch. The compact tip size suits precision work on small-diameter pins and roll pins found in motors, linkages, and mechanical assemblies.

The PROTO J505/16 is suited for use in both residential and commercial maintenance environments. It is commonly used on motor assemblies, control linkages, valve bodies, and any mechanical component requiring pin extraction or fastener removal. The 5-1/8 inch overall length provides a practical balance between reach and hammer control in confined work areas. This punch is appropriate for bench work and in-field service calls where reliable hand tools are essential.

Key Features

• 1/8 inch punch tip for driving small-diameter pins and fasteners
• 5-1/8 inch overall length for reach and hammer control
• Steel construction for durability under repeated impact
• Starter punch geometry designed to initiate pin removal before transitioning to a drift punch

Compatibility

Designed as a general-purpose starter punch suitable for use on mechanical assemblies requiring small-diameter pin extraction across a wide range of trade and maintenance applications.

Installation Notes

A licensed mechanic, pipefitter, or trained technician should use this punch with an appropriate ball-peen or cross-peen hammer. Always wear safety glasses when striking punches to protect against metal fragments. Secure the workpiece firmly before driving to prevent movement and potential injury. Use a starter punch only to begin pin removal, then follow with an appropriate drift punch to complete the operation.
