The different types of reamers
reamers are cutting tools used in machining processes to enlarge or shape an existing hole. They are used to achieve precise dimensions and smooth finishes. There are several types of reamers available, each designed for specific applications.
Straight reamers
Straight reamers are the most common type of reamers and are used for general-purpose reaming. They have a cylindrical shape with straight flutes and are available in various sizes. Straight reamers can be used on a variety of materials, including steel, cast iron, and non-ferrous metals.
Shell reamers
Shell reamers, also known as piloted reamers, have a pilot or guide attached to the shank. They are used for reaming large diameter holes and are commonly used in automotive and aerospace applications. The pilot helps align the reamer and maintain concentricity.
Adjustable reamers
Adjustable reamers are versatile tools that can be adjusted to achieve different hole sizes. They have a set of blades or inserts that can be expanded or contracted to the desired diameter. This makes adjustable reamers suitable for reaming holes that are slightly out of round or have irregular shapes. They are commonly used in maintenance and repair applications.
Tapered reamers
Tapered reamers have a tapered shape and are used to ream tapered holes or deburr holes. They are often used in conjunction with other tools, such as counterbores or countersinks, to achieve a desired shape and finish. Tapered reamers are commonly used in woodworking and metalworking applications.
Bridge reamers
Bridge reamers are designed for reaming holes that are already partially drilled. They have a long, tapered shape and are used to widen and align the hole. Bridge reamers are commonly used in construction, plumbing, and electrical applications.
