Abstract
In a housing (22) for a right-angle grinder (20), a pair of clamshell sections (24) and (26) are joined along a midplane (28). The interior of the housing (22) is formed with a motor case (34) and a gear case (36). Clamshell section (26) is formed with a rib (76) in a peripheral edge (72) thereof and is nested in a groove (58) formed in a peripheral edge (56) of clamshell section (24) to form an interlock for the housing (22). Slots (78) and (80) are formed transversely through the rib (76) along two spaced paths of the interlock to preclude a flowable lubricating substance from creeping from gear case (36), along the two spaced paths of the interlock to the motor case (34).
