Reaming is a machining process used to enlarge and smooth the interior surface of a hole. It is often employed when precision sizing and smooth finishes are necessary, such as in reamed holes for components like bearings, bushings and dowel pin sockets. Reaming can produce very accurate results when done correctly, but getting the best results requires careful preparation, the right reaming tools and proper technique.
In this guide, you will learn how to ream a hole correctly for maximum accuracy and precision. You’ll also discover tips for reaming larger holes and considerations for selecting the best reaming tool for your project.
With these tips in hand, you can ensure success with reaming every time

How to choose the right reamer for the job
Reamers are cutting tools used to enlarge and shape an existing hole in a material, such as wood or metal. When choosing a reamer for the job, you need to consider several factors, including the type of material being worked on, the size of the hole needed, and the speed at which it needs to be created.
Reamers come in a variety of shapes, sizes and materials. For example, there are straight flute reamers designed for use on soft materials such as wood, spiral flute reamers designed for hard materials such as metal, and adjustable reamers that can be used on both. When selecting the right reamer for your job, consider the material you’re working with and choose one that is specifically designed to work with it.
You also need to determine what size hole you need before purchasing a reamer. Measure the existing hole diameter carefully so that you select a reamer which will create a slightly larger opening than desired by taking into account any internal tapers or angles in the material.
Finally, consider the speed at which you need to create the hole. Some reamers are designed to cut quickly while others require more time and effort. Select a reamer that will provide an accurate result in the amount of time necessary for your project. By following these guidelines, you can choose the right reamer for your job and ensure that it will get done efficiently and accurately.
How to properly use a reamer
A reamer is a tool used to enlarge and smooth the interior of round holes in a workpiece. It is important to use the correct type and size of reamer when enlarging an existing hole, as well as the correct cutting oil or lubricant. When using a reamer, always make sure that it is properly fitted into the chuck or collet of your drill press, milling machine, or other machine tool.
Make sure that the cutting edges of the blades are parallel with the axis of rotation before starting. Start at slow speeds until you have established a good cut rate and then gradually increase speed with each pass. If chatter occurs back off on feed pressure and reduce speed until chatter subsides. Make multiple light passes, rather than one heavy pass to achieve the desired size and finish. Keep the reamer cool by using cutting fluid or lubricant.
After use, clean and inspect the reamer for any wear or damage before storing it. Following these simple steps will ensure that your projects are completed with precision and accuracy.
Know the size of your reamer
Knowing the size of your reamer is an important factor in determining the effectiveness and accuracy of your drilling.
Reamers come in a variety of sizes, each designed to create a specific inner diameter for your drilled hole. If you select the wrong size reamer, or one that is too large or small, it will not successfully produce the desired results. For example, if you’re using a standard 1/2 inch drill bit, then you’ll need a 1/2 inch reamer. A larger drill bit will require a correspondingly larger reamer.
The size of a reamer directly affects its ability to cut material accurately and precisely; larger reamers require more torque during operation which can cause them to chatter or skip over surfaces if they are not strong enough. Smaller reamers may be able to provide greater accuracy but will have difficulty removing material efficiently if used on tougher metals or woods.
Additionally, many jobs may require more specialized tools such as taper reamers or adjustable reamers that can be adjusted to fit any size up to their maximum capacity. It’s also important to consider how deep you need to drill before selecting a reamer size; this will help ensure that you don’t end up with a tool that’s too large for the job. Choosing the right size reamer can make a world of difference in your drilling projects, so make sure to take the time to get it right!
