Beach RC says... This is the AKA Pro Multi-Tip Tire Punch, an update to the most popular tire punch on the market. The redesigned Pro Multi Tip Tire Punch features a cantilever design to increase punch pressure and reduce hand fatigue. The redesigned handle has plastic cover on the lower handle to more comfortably fit your hand. The multi tip rotating head offers sizes from 2mm to 4.5mm and has a convenient waste box for the discarded rubber.
