Reamers are precision cutting tools commonly used in machining operations to enlarge or tidy up drilled holes. They are designed to remove material from the interior of a hole, creating a smooth and accurately sized hole with a high-quality finish.
In terms of construction, reamers typically consist of a solid cylindrical body with spiral flutes running along its length. The flutes aid in the removal of material as the reamer is rotated. At the cutting end, reamers have a beveled edge or cutting teeth, which perform the cutting action. The cutting teeth of a reamer are often made from hardened high-speed steel, carbide, or other durable materials, ensuring long-lasting performance.
Reamers are used when high precision and accuracy are required in the hole diameter. They can be employed in a wide range of materials, including metals, plastics, and composites. Reamers are often used to provide a close tolerance for inserting fasteners or precision components, ensuring proper fits and reducing friction between mated parts. They are commonly used in industries such as automotive, aerospace, manufacturing, and machining.
The selection of reamers considers factors such as the desired hole size, material being worked on, and the required finish. Various types of reamers are available, including hand reamers, machine reamers, adjustable reamers, and reamers with taper shanks, each designed for specific applications.
In summary, reamers are cutting tools used to enlarge or refine drilled holes in order to achieve accurate dimensions, smooth finishes, and proper fitment.
