How to Refill a Mechanical Pencil

What is a Mechanical Pencil?

A mechanical pencil is a ballpoint pen Esque pencil that has a lead advance mechanism in it. It is fully regulated and run by a lead that can be changeable and refillable.

Once the lead gets broken or finishes, you can change the lead accordingly. These leads are available in the market separately. The chamber of the pen allows the lead to get inside it.

Mechanical Pencils have different kinds of names in different parts of the world. ‘Automatic pencil’ and ‘propelling pencil’ are commonly used terms in the European side. People also sometimes term it as ‘clicky pencils.

This is one of the most feasible means for everyday life usage. Everyone in office to schools and colleges can use this like a ballpoint pen. The pencil gives you the scope of perfect wiring, correcting, and signing on different papers, documents, etc.

You get to work with it as a usual wooden pencil for detailed drawing from time to time. It is one of the most versatile writing instruments in the world at the moment.

In the long run, a mechanical pencil is an excellent choice to have. Surely it will boost your writing capabilities to a new stage.

Are All Mechanical Pencils Refillable?

All the mechanical pencils don’t have to be refillable. But most mechanical pencils in the market are refillable and can be adjusted with branded leads like ballpoint refills.

Usually, you’ll see most mechanical pencils in the market require 0.7mm lead to be inserted in them. Depending upon overall usage and compatibility, it is the most suitable one to have.

For your everyday writings, signatures, drawings, you can use the lead ideally. Once the lead breaks or becomes unusable, you get to replace it with a new one.

You can get them while buying the pencil or separately from the store as a whole. Refill them inside the pencil, and you are set to use the pencil again as usual.

Steps to Refill a Mechanical Pencil

Knowing all the feasibility of a mechanical pencil, now it is time to make the best use of it. Let’s get to know how to refill a mechanical pencil in some convenient manners.

Step 1: Identify the Pencil Type

Identifying the pencil doesn’t mean having a specific pencil type to undergo the lead replacement. You just need to be sure that the type of mechanical pencil you are using has access to refilling.

Most of the cheap mechanical pencils in the market do not have the feature. This makes most of your buy not sensible for the long run. That’s why it is a win in all situations to buy a mechanical pencil that can be refilled further after use.

Step 2: Pick Up the Right Lead

 Lead selection is essential. Based on your pencil’s type and characteristics, you need to select the correct size lead for your pencil. For example, your pencil requires a lead of 0.5mm; so, you have to get the lead that is 0.5mm.

Any lead out of the box or the wrong size will not work for you.

Also, you need to consider the durability of the lead. Keep in mind, the broader the lead, the stronger it is. That makes clear sense that the classic size 0.7mm lead will be stronger than a 0.5mm one.

But using the 0.5mm lead is more convenient and more accessible. Because the lead gives you all the scope of using it almost for all daily necessities, be it writing, art, drawing, sketching, etc. And being a little careful, you can make full use of it.

Make sure you are getting the best lead for yourself based on what you will use it for.

Step 3: Open Up the Filling Chamber

The filing chamber of the mechanical pencils is quite different based on the models of the pencils. They usually remain on the opposite side of the pencil’s tip, i.e., on the side of the eraser. You’ll find the chamber mainly after removing the eraser head.

Again, some lead opening comes from the face of the tip of the pencil. Usually, you get to insert the lead inside the mouth, having a gripper holder on the other side.

Pressing the gripper holder opens the scope for inserting the lead, and you can fill it accordingly. The cheap pencils usually have this feature.

The primary step in refilling your mechanical pencil is opening the filling chamber slowly and carefully. The cap covers the end of your pencil and lead; it gives an excellent balance to the lead in remaining inside the pencil.

Step 4: Clearing Inside

Before you insert the lead inside, take a closer look at the inside of the chamber. There are possibilities of having broken leads stored inside it.

When you try to refill the pencil with a new one, you might face difficulty doing so. Not only that, your lead might get broken due to extensive pressure and congestion.

It will be your prime duty to clear the pencil inside. Just give a multiple shaking of the pencil, keeping it upside down. The lead would’ve fallen by that. If needed, you can use a cotton bud or a stick to clean the inside part.

Step-5: Refill the Leads

Accessing the chamber correctly, now it’s time to insert the lead accordingly. As the lead is not that solid or durable, you have to be gentle while dealing with it. Any kind of extreme pressure on it will surely break it into pieces.

You have to work gently on it then. Determine the chamber of the pencil and open the lid of it (if you have any). Take the lead gently and insert it inside the chamber.

Make sure the lead is of perfect size. Length and girth should be appropriately determined. After you are done refilling the lead inside, close the chamber or release the gripper button.

Step-6: Reassemble Everything

After you are done with the refilling, but the accessories are to the position accordingly. Put up the eraser in its usual place and make it ready for your desired operations.

One of the most amazing things about the pencil that keeps it long-lasting is its refill ability. You get to change and replace the lead again and again without any hassle.

But you need to make sure the mechanism and spring inside the pencil remain active and exemplary. Otherwise, you won’t be able to click and use the pencil as usual.
