Product Description

The STARRETT 51186 is a 5-piece standard pin punch set designed for driving out roll pins, dowel pins, and tapered pins in mechanical assemblies. Each punch features a round shank machined from steel for durability under repeated impact. The set covers a size range from 0.125 inches to 0.375 inches, making it suited for a broad range of fastener and pin removal tasks encountered in HVAC equipment service, electrical panel assembly, plumbing fixture work, and general mechanical maintenance. All five punches store in an included vinyl pouch for organized transport to job sites.

This set is appropriate for trade professionals who need reliable pin punch coverage across common sizes without carrying individual punches. Typical applications include removing hinge pins, aligning components during assembly, driving out retaining pins on valves and actuators, and servicing mechanical linkages. The five sizes included are 0.125 inches, 0.1875 inches, 0.25 inches, 0.3125 inches, and 0.375 inches, providing incremental coverage across the range.

Installation Notes

Pin punches are installed and used by mechanics, HVAC technicians, electricians, and plumbers during equipment disassembly and assembly. Always ensure the workpiece is secured in a vise or on a stable surface before striking. Use an appropriately sized ball-peen or mechanics hammer rated for punch work. Select the punch size that closely matches the pin diameter to avoid deforming the pin or the surrounding bore.
