Five-Size Roll Pin Punch V-Guide
This V-block guide keeps a pin punch square to a round shaft while you drive out a roll pin, for example when replacing a stripped garage-door-opener gear, a worn blender coupler or a sheared pin in a crank. It is 120 x 28 x 30 mm. The 90° V-groove fits 5–30 mm shafts, and five slip-fit bores for 3, 4, 5, 6 and 8 mm punches all sit on the V's centre plane, so whichever bore you use lines up over the shaft's cross-hole. A zip-tie tunnel at each end straps the guide to the shaft.
