Reamers

A reamer is a tool used for cutting that uses a rotary function. It’s used for metalwork and forms small, precise holes with a high level of accuracy and a smooth finish.

Non-precision reamers are used in more rudimentary holes or for removing burrs. Remaining is the name given for the process of enlarging a hole. There are several kinds of reamers with slightly different functions. They are available as either a hand tool or a machine tool.

Parts of a Reamer

There are three primary components of a reamer – the fluted part, the neck, and the shank.

The fluted section comprises a chamfer (which ensures a clean entry into the hole), a starting taper (performs the main cutting action), a sizing section (guides the reamers), and a back taper (reduces friction).

Types of Reamers

There are several types of reamers, each designed to perform different cutting tasks. These include: adjustable reamers, chucking reamers, expanding reamers, flute reamers, hand reamers, machine reamers, and shell reamers.

Adjustable Reamers

These reamers insert individual blades into the grooves of the body of the reamer. The blades can be adjusted to move up or down for added control.

Hand Reamers

As the name suggests, hand reamers are operated manually. They have a tap wrench attached to the sequence of the reamer. Metalwork is held in a vice and flutes can be either straight or in the shape of a helix. The shank is straight and has a square tang for the wrench.

Machine Reamers

Machine reamers are very much like hand reamers with the exception that the shank is tapered.

Chucking Reamers

The main difference between a chucking reamer and a machine reamer is shorter flutes. These are used for heavy roughing cuts and will likely have either a rose reamer or a fluted reamer.

Fluting Reamers

Fluting reamers do not have rigid holders; they instead use fluting. This makes holes with less restraint and leads to better results.

Expanding Reamers

These reamers are bored, tapered, and slit. The hole end is controlled by a screw which functions as an expander.

Tapered Reamers

These are the perfect reamers to use for finishing taper holes and securing collars to the shaft.

Shell Reamers

Robust reamers of around 20 mm in diameter are called shell reamsers. They can attach to a typical shank made from inexpensive steel. They can also be used in conjunction with cemented carbides.
