When a Hole Is Reamed In Metal to Size – Is it Grooved or Not?

Do you want to ream your metal hole or are you wondering what happens when the hole is reamed? Reaming a hole of metal is a useful process as it facilitates you in creating the hole in your desired diameter. In addition, this process increases the finishing and accuracy of the hole.

So, if you are wondering about the ways to resize the hole of your metal or you are wondering when is the right time to ream your metal, you can read this article.

Without further ado, let’s dive into it!

How to Enlarge an Existing Hole in Metal?

If you are doing metalwork to finish an important project, you need to expand or line up the hole in the metal pipe. A reamer is used to doing this job most of the time. People use it to enlarge the existing hole of the pipe but do not cut it. Professionals who are involved in metalwork know how to drill a hole in metal with a reamer. 

When a Hole Is Reamed In Metal to Size?

When a hole is reamed in metal to size, it enlarges the size of the hole and presents you with a precise size hole, meaning the size you want. The process of expanding the already present hole in metal is called reaming. 

People use this vital process to enlarge the hole in any metal device, so you don’t have to rethink the chosen process. It allows you to create a hole of circular shape in diameter that you need. You need to make a hole using a drill machine and expand it to the diameter you want. This is the finishing process of the already present hole with full accuracy. When we discuss when a hole is reamed in metal to its size, you also need to know its important tools. 

Necessary Tool Used for Enlarging Holes:

The necessary tools needs for reaming are as follows:

1.) Unibit:

The Unibit is a fantastic tool to drill holes and expand them. This is perfect for using soft materials, e.g. acrylic, plywood, etc., and metals such as stainless steel and sheet material. You are allowed to make a hole of different diameters by using drill bits with a stair-step profile. Remember larger the bit size, the more it will expand the hole. 

2.) Holesaw:

Holesaw is another useful tool used to expand the hole size in wood, plastic, metal, and more. This is suitable for practical and professional designs and comes with a sharp blade to make a big hole in the material. But it is not so easy to enlarge the already present hole because hole saws depend on a pilot bit to guide them.

3.) Knockout Punch:

If you are an electrician, you must be familiar with the name of a knockout punch. It is used generally to expand hole size or to create a new one. This amazing tool is found in metal electrical boxes for making holes. This is simple to use, and this hand tool can expand holes in the sheet metal.

4.) Reamer:

Mechanical engineers said that the market is flooded with different types of reamers based on their function. The types include hand reamer, chucking straight fluted reamers, taper pin reamer, jobbers reamer, and shell reamer. These types are rotary cutting tools and are used to enlarge the diameter of an already present hole. It is readied with two or more flutes or peripheral trenches that are made of high carbon steel. 

Drilling Hole in Metal (Step By Step Guide)

Are you wondering about the ways to drill the hole of metal? Here is a step-by-step guide to drilling holes in metal. Explore some easier and more reliable ways!

1.) Securely Fix the Workpiece:

Firstly securely fix the workpiece so that it can not move from your workplace. 

2.) Choose Appropriate Reamer:

According to your required hole size, pick the most suitable reamer. Be very careful and choose reamer as per the material, the desired accuracy, required diameter, finishing, etc. 

Pick the right one as it has an impact on the hole size. For industrial suppliers, many reamers are available, having thousands of inches and hundreds of millimeter increments. So perform reaming with care, as this is a vital step.

3.) Fit the Reamer to the Drive Tool:

Now properly equip the reamer to the driver tool. And then you need to pick the accurate adapter. 

4.) Choose the Correct Adapter:

Choosing the appropriate adapter is necessary when you use a magnetic drilling machine, Holemaker Technology reamer in a socket wrench power tool, or SDS drilling machine. Inject the reamer by fitting the adapter to the drive equipment. After this, fit the reamer into the drill and properly tighten the screw.

5.) Insert Reamer into the Hole:

To widen the hole, insert a reamer in it. When setting the reamer with a magnetic drill into the hole, ensure that you turn off the magnet drill to make the reamer move correctly. 

6.) Start the Cut:

Now start cutting by steadily applying the pressure. Try to keep the speed of the reamer half, and it would be better to make the feed double. Try that reamer reach to the hole as deep as the hole size is needed. When you finish the cut, stop the reamer and withdraw it from the hole.
