The Klein Tools conduit-fitting and reaming screwdriver can ream and smooth 1/2 in., 3/4 in. and 1 in. thin-wall conduit. It features a hooded-blade design that keeps the screwdriver tip from slipping out of screws, which is especially handy when tightening hard-to-reach conduit fittings. This screwdriver has a longer cushion-grip handle for even.
