Reamers are precision tools used in machining to enlarge holes to a specific diameter and improve the surface finish of the hole. The dimensions of these particular reamers are .1925 inches in diameter, .2344 inches in diameter, and they measure 3-14/16 inches in length. This specific design makes them suitable for applications that require high accuracy and fine tolerances. Historically, reamers have been utilized since the early days of metalworking. They are used in various industries such as aerospace, automotive, and manufacturing, where precision is critical. Reamers can create a smoother finish compared to drilling and can be found in both hand tools and machine tooling applications. This unbranded reamer features both a fractional and decimal dimension which allows for versatility in different applications. Its construction is typically high-speed steel or carbide, offering durability and resistance to wear. The design usually includes cutting edges that are slightly larger than the intended hole size to achieve a precise fit after machining. Given their dimensions, these specific reamers are ideal for tasks requiring exactness, such as preparing holes for fasteners or ensuring proper fits in assembly processes.
