Choosing Your Drill Bit Extensions- Important Considerations
When choosing your drill bit extensions, there are several considerations you need to make, these are;
- The length of the operation or job needed,
- Shank size of the drill bit
- Directional tool
- Does it fit Hex bits or only Round shanks?
The length of the operation or job needed must be measured before you choose the extension appropriate for such. Failure to follow this rule may mean you wouldn’t achieve the right drill efficiency and you may end up performing shoddy jobs.
The shank size of the drill bit must be measured before choosing your drill bit. The shank size is the end that simply stuck to the drill. It must fit perfectly into the drill to allow you to tighten the set screws in order to secure the bit into the long extension.
Adding a directional tool to the drill bit extension can also help in a number of ways. A drill bit directional tool will provide more stability and control for the drill bit user, especially in situations where the drill bit can be unwieldy.
Some extensions are not designed for hexagonal or other shapes of bits; hence you need to check whether the one you choose is designed for only round bits or various shapes. The ideal extension drill must fit most standard shaft sizes and must be suitable for multi-floor drilling. Any extension that doesn’t fit into different floor drilling situation is not suitable. You should also consider extension drills that are flexible for different operations.
When Should A Long Extension Becomes Necessary For A Drill Bit?

If you want to place some roof tiles down and you don’t have enough space to swing the hammer, then the extension for the drill bit to simply bend the extension into the tight region to handle the work.
The extension for the drill bit is handy for any tight spot or work region where hidden holes and screws will require the application of extension for a drill bit to save you time and energy.
How To Change Drill Bits With Extension
There are few steps to take when changing drill bits with extensions, these are;
1. Loosen the chuck
The chuck is that piece located at the end of the drill that can loosen and tighten to hold the bits and extension. Simply grab the chuck with a hand, and hold the drill handle with the other hand, then twist the chuck in a counterclockwise motion to loosen it. When you loosen the chuck, it will open the jaws that clamp into the drill bit.
2. Remove the Drill Bit
Once the chuck has been loosening, you will have access to the drill bit that is currently in the chuck will start wobbling, and you can easily pull it away from the drill because the jaws that clamp it to the drill has loosened up.
3. Set the Drill Bit
Simply hold the bit in place with your thumb, alongside the index finger, in such a way that the shank faces the chuck jaws. Gently insert the bits into the chuck and almost immediately pull it back towards you about a centimeter distance. Make sure your fingers are kept on the bit alongside the chuck since the bit may fall out.
4. Squeeze in the Trigger
Once the bit has been inserted, your next move is to tighten the bit into its place by simply giving the trigger some extra short squeezes (the trigger is controlled by that yellow lever, which you can press to tighten or loosen the bit). While pressing the trigger, make sure your hand is still holding the bit loosely.
5. Make Use of the Ratcheting Mechanism if Needed
If the drill comes with a ratcheting mechanism that can help you apply extra pressure on the shank of the drill bit, then you need to click such a mechanism into place. In order to engage this mechanism, simply twist the ratcheting mechanism firmly, in a clockwise motion, next to the chuck.
6. Insert the Extension
You will need the chuck key in order to attach the extension for the drill bit. The chuck key is needed to loosen the chuck. Make sure you line up the teeth so that they match the teeth of the chuck and then insert the tip of the key to one of the holes located on the side of the chuck. You will likely see a key chuck on the power drill and not the cordless options.
7. Turn your Chuck Key Counter-clockwise
As you are turning the chuck key, the jaws on the chuck will simply begin to open. Make sure you continue turning the key until the chuck has opened enough in order for you to slide the drill bit out easily.
8. Remove the Bit
Simply pull the bit out of the chuck with the aid of your thumb as well as the index finger, once the chuck has been loosened. If the chuck has opened wide, and the drill is turned facedown, then the bit will simply fall off.
Make sure you inspect the bit once it has been removed to see if there are worn or damaged regions. You need to replace it if it is dull and before you attach the extension. If the bit also shows signs of cracking or bending, simply throw it away so that you don’t put it back accidentally.
9. Insert the new Bit and Extension
While the jaws of the chuck are still opened widely, simply insert the extension and the bit. Simply hold the bit with the thumb finger, alongside the index finger in such a way that the smooth part of the shank is facing the chuck jaws, and then insert the bit with the extension. Make sure your fingers are kept on the bit because it is not secured yet and may fall out.
10. Tighten the Chuck
Once the extension and new bit have been installed, you must tighten the chuck. While you are still holding the bit in place with a hand, then turn the chuck key in a clockwise motion in order to tighten the jaws of the chuck with the other hand. Make sure it is tightened firmly in order to secure the bit. Once the extension and bit have been secured, you can remove the chuck key. Remove your hand from the bit and extension once they are secured and test before using it.

What To Look Out For When Buying Extensions For Drill Bits
There are a number of factors you should consider when buying extensions for drill bits and these considerations can help you make the ideal choice. The main factors you should consider are;
- Length of extension.
- The material of extension.
- Types of Loading System.
- Magnetic or non-magnetic.
- Flexible or non-flexible.
It is easy to settle for any type of extension length when buying the accessory but in essence, the longer the extension the better. Don’t go for a 12” extension when you will need something longer for many jobs you will be handling during home renovation or construction work. Shorter extensions may include the 2”, 4”, and 6” which are very convenient for short-distance jobs.
The material used making the extension matters because it may add to its longevity. You may be fine with steel extension with no extra plating but improper storage and handling can cause corrosion of the extension especially when it comes with lower-grade steel materials.
Extensions made with chrome-plated sleeve and carbon steel body extensions last longer, and they look more premium but will likely cost more than the steel-plated extension. If you are conscious of budget, perhaps you should opt for the stainless steel extensions with no extra plating but make sure the steel grade is of top quality.
The type of loading system an extension is also a key feature you should consider when buying an extension. The lock and load system has been found to be more convenient and more effective in the sense that it releases itself quickly for quick changing of drill bits. The lock and load system is, therefore, more economical especially when you have to perform so many jobs quickly, and it saves time and energy.
Though, the choice of going for magnetic or non-magnetic extensions for drill bit should only be a personal thing. Magnetic extensions may be more efficient because they offer more superior access to hard-to-reach places when handling a job. The magnetic effect means the extension will get stuck to the bits even more efficiently thus leaving no room for misalignment.
The compatibility of an extension also matters. The more compatible an extension is, the more effective and more economical it is. Go for an extension with a patented jaw design that is compatible with all the ¼” hex shank accessories.
When it comes to choosing between flexible or non-flexible extension, perhaps you need to consider your personal needs. Though the flexible extension can bend easily, hence it can reach even more difficult areas, you may not actually need such if you can use a shorter extension to reach such places.
When it comes to the issue of the price of extensions, many things will determine the costs of the product you choose. For instance, longer extensions are more expensive than shorter ones. You should also expect a carbon-plated or chrome-plated extension to be more expensive than an ordinary steel extension. If you are buying a pack of several extensions, the cost will be higher than buying a single extension, which means the inclusion of other accessories can equally make the product cost more.
As mentioned before, the most expensive extension is not always the best drill bits extension out there; you need to be aware of the specifications that will suit your personal needs before making your final choice. If you can’t be certain about your personal specifications, perhaps you should consider purchasing a shorter and longer extension to complement each other at various times.
Fortunately, there are some possible ways to use more than one extension at the same time to handle tougher or deeper drilling jobs. You may also want to consider magnetic extension options that provide even better stability and reduce cases or chances of shifting of drill bits inside.
This review has given you an insight into how you can choose the right types of extensions for your needs. Pay attention to the recommended products and compare them in terms of length, compatibility, and strengths when making your final choices. Perhaps you may want to seek some expert advice from tool shops and individual drill bit extension owners to be certain that you are making the right choices.
You need to be careful when purchasing fairly used or refurbished extensions for drill bits, such products may not be in their best conditions and may create problems within a short period of time, thus making you lose money in the long run. Refurbished and fairly used extensions are known to bend or break after a few days or weeks of usage, unless you are sure of the source you are buying from, you should avoid payments for such used items.
