Adjustable hand reamers have nuts and blades that can be adjusted to allow the tool to enlarge or finish holes of different sizes in metal workpieces. These hand reamers are held with a tap wrench, adjustable wrench, or vise and are slowly rotated to feed the reamer into the hole. Adjustable hand reamers have a tendency to chatter and are a good choice for occasional reaming tasks or for light-duty reaming in assembly and maintenance operations. These reamer sets contain multiple adjustable hand reamers in a range of sizes.
