Mayhew 1/2 x 8 Pin Punch (21017)
The Mayhew 1/2” x 8” Pin Punch (21017) is a specialized hand tool designed for precise and efficient removal of pins and keys that have already been loosened. Its primary function is to complete the extraction process after a solid punch has initiated movement. Crafted in the USA, this punch features a durable black oxide finish that provides an additional layer of protection against rust and corrosion, extending the tool's lifespan and maintaining its appearance even with frequent use. The 1/2-inch pin width is ideal for a range of common pin sizes, while the 8-inch overall length offers good reach and leverage for various applications, from automotive work to machinery maintenance and general repair tasks. The hexagonal body design ensures a secure grip during use and prevents the tool from rolling on flat surfaces.

Identify the Pin: Locate the pin or key you need to remove. Ensure it has already been loosened or started moving by a solid punch or other initial force.
Select the Correct Punch: Choose the Mayhew 1/2" Pin Punch if the pin diameter matches or is slightly larger than 1/2 inch. The punch tip should fit snugly against the pin without slipping.
Position the Punch: Place the tip of the Mayhew 1/2" x 8" Pin Punch directly onto the center of the loosened pin.
Strike the Punch: Using a hammer of appropriate weight, strike the flat end of the punch squarely and firmly. Apply consistent force to drive the pin out cleanly.
Monitor Progress: Continue striking until the pin is fully pushed through the material. Ensure the pin exits the other side safely.
Clean Up: Once the pin is removed, clear any debris from the area.
