Reamers are cutting tools used for enlarging and finishing the diameter of a pre-drilled hole to a precise size and surface finish. They are used in various industries, such as automotive, aerospace, and manufacturing. Here’s what you need to know about reamers:


Reamers are used for a wide range of applications

, including:

1. Precision hole sizing: Reamers are commonly used for creating precise holes with a high degree of accuracy and surface finish.

2. Hole finishing: Reamers are also used for improving the surface finish of a pre-drilled hole, ensuring smooth and straight walls.

3. Removing burrs: Reamers can be used for removing burrs or sharp edges left after drilling or cutting operations.


Reamers are available in various types, each designed for specific applications:

1. Hand reamers: These reamers are designed for manual use, requiring the operator to turn the tool by hand.

2. Machine reamers: These reamers are designed for use with a drilling machine or lathe.

3. Tapered reamers: These reamers have a tapered shape and are used for creating tapered holes or for finishing the inside of a tapered bore.

4. Adjustable reamers: These reamers have blades that can be adjusted to different diameters, making them versatile and useful for a range of applications.


To ensure the safe and effective use of reamers, it’s important to take the following precautions:

1. Use appropriate personal protective equipment, such as safety glasses, gloves, and a dust mask.

2. Select the appropriate reamer for the specific application.

3. Use cutting fluids to reduce heat and friction and improve tool life.

4. Use slow and steady pressure when reaming, avoiding sudden changes in speed or direction.

Reaming Operation:

To perform a reaming operation, follow these steps:

1. Select the appropriate reamer and mount it securely in the chuck of the machine or by hand.

2. Apply cutting fluid to the workpiece and the reamer.

3. Turn on the machine or start turning the reamer by hand, applying steady pressure.

4. Once the reamer has reached the desired depth, reverse the direction and withdraw the tool slowly.

5. Remove any burrs or debris left behind by the reaming operation.

Overall, reamers are a versatile and essential cutting tool used in various industries for precision hole sizing and finishing. By following the proper precautions and techniques, you can ensure the safe and effective use of reamers in your operations.
