Summary: Enlarging and finishing holes.      

Reamers are rotary cutting tools used to enlarge or finish existing holes to precise dimensions and smooth finishes. They're designed to remove small amounts of material, unlike drills which create the hole initially. Here's a breakdown of the types you mentioned:

Hand Reamers: These are operated manually and are used for very precise finishing of holes, often in applications where a high degree of accuracy is required. They have a long, gradual taper at the front to aid in starting the cut.

Machine Reamers: These are designed to be used in power-driven machines like drill presses or milling machines. They can remove material more quickly than hand reamers and are suitable for higher production volumes. Machine reamers come in various types, including chucking reamers and shell reamers, optimized for different machining operations.

In essence, reamers are crucial tools for achieving accurate hole sizes and smooth surface finishes in metalworking and other manufacturing processes.
