Wiha SoftFinish CentroFix bittikahva ruuvitaltta 1/4" (6,3 mm) 38 mm 40331

For electricians and technicians who frequently swap bits during panel work or equipment assembly, the Wiha SoftFinish CentroFix bit holder screwdriver keeps the pace fast and the grip comfortable. Its 1/4" (6.3 mm) CentroFix holder locks bits mechanically, so they stay put until you release them. The 38 mm shaft reaches into recessed screw locations, while the SoftFinish handle reduces hand fatigue over long shifts.
