Precision machined, non-marring brass punches drift sights and drive pins without risk of damage to the sight, pin, or firearm. We combined 20 of our most popular non-marring brass punches, added a compact bench block and came up with a great addition for the work bench. Features (4) starter punches, (8) roll pin punches, and (8) standard punches for a variety of different jobs. Delrin® bench block holds and organizes all 20 punches for easy access, plus is resistant to most solvents. Starter punches are used to start the removal of steel or aluminum pins. Short, tapered shaft is extra stiff to prevent bending and twisting. Roll Pin punches feature a special tip that centers inside the hollow pin to help prevent slippage when driving roll pins and spring pins. Standard punches are non-tapered with a flathead tip surface that works great for drifting front and rear dovetail sights. Complete set includes bench block, also available separately.
