Proto 1/4" X 6" Brass Solid Punch J501X4B-SBD

Proto's professional-grade starting punch (also known as a pilot or starter punch) designed to initiate the removal of pins or rivets in heavy-duty industrial and automotive applications. This tool features a robust, tapered design that provides the necessary strength to withstand the high-impact force required to "break" a fastener loose before a standard drift punch is used to finish the job. Constructed for maximum durability, the punch includes a modified parabolic striking end to reduce mushrooming and chipping under heavy use. Its precision-machined tip ensures accurate contact with the fastener, while the black oxide finish provides superior resistance to rust and corrosion. The shipping weight for this model is approximately 0.14 lbs.
Key Features
Specialized starting tip is designed to provide the concentrated force needed to initiate the removal of stubborn pins and rivets.
