The Master Bench Block Pro-Kit is a comprehensive pin punching solution that simplifies your work. This all-in-one set includes 18 hardened steel punches and an ergonomic hammer with interchangeable heads stored within a spacious bench block. With 14 strategically placed holes, 2 grooves and a larger design, precise pin alignment is made easy for all firearms. The three elongated slots quickly align with compact size to full size pistols. To help secure parts, frames or barrels firmly in place, two Smart-Block Clamps have been incorporated into the block, allowing the end user to focus purely on the task at hand. When the work is done, store all your tools into the integrated storage tray for an easy storage solution.
