Proto, J501/4S2, Starting Punch, 4.700 in; S2 Steel; Black Oxide Finish

Engineered for precision and durability, the Proto Starting Punch is designed to facilitate the installation and removal of pins and shafts with ease. Crafted from S2 steel and heat-treated for enhanced strength, this tool features a modified parabolic striking end that minimizes mushrooming and chipping, ensuring a longer lifespan. Its one-piece construction contributes to its durability, while the black oxide finish not only provides a sleek look but also offers protection against rust and corrosion. Measuring 4.700 inches in length with a reverse taper to prevent binding, this punch is similar to drift punches but features wider points and a thicker, shorter body for improved performance. Ideal for aligning holes in metals for bolt or screw insertion, this tool also includes a polished identification panel for easy size recognition.
