How do I know what size masonry bit to use for a 3/8" rod anchor?

A standard 3/8-inch drop-in (female) anchor typically requires a 1/2-inch masonry drill bit . Always check the stamp on the side of the anchor box; a wedge anchor (male) uses a bit matching its thread diameter (3/8-inch), but a drop-in (female) anchor requires a larger bit to accommodate the anchor sleeve wall thickness.
