The term 'Widen a Hole' can be solved by the four letter word 'REAM'. Reaming is a process used to enlarge and smooth a hole in a material. It is usually done with a tool called a reamer, which is a type of drill bit that has multiple cutting edges. The reamer is inserted into the hole and rotated, removing material from the sides of the hole and making it larger. Reaming is often used in manufacturing and construction to create precise holes in materials such as metal, wood, and plastic.
