Let’s start by looking at the difference between the two jigs.

Key Difference Between Kreg K4 Vs K5 

Kreg k4 and k5 may look similar in certain aspects, but they have many features that make them perform different functions. To make an informed decision about which model will provide you with the versatility and functionality for your project, you need to understand these differences.

What is a Jig?

A jig can be defined as a device/tool accessory that holds a piece of material being worked on and guides the tool working on the material. Jigs have a plate or frame shape but have different features and designs, depending on their intended application. However, all of them have machined edges, pre-drilled holes, among other features.

All these features will help you make repeatable and consistent material fabrications. These devices come in different shapes and sizes. So you can get the exact fabrications without having to align or adjust any component manually.

Jigs ensure the material worked on is stable. They guide tools like drills and saws in the desired direction with ease. Jigs are mainly used by woodworkers and other fabrication specialists who want to make accurate and precise cuts.

Some jigs are specifically designed for DIY projects, while others are designed for heavy-duty works. So before you buy any jig, find out which one will satisfy your requirements better.

What Is Kreg? Who Are They? 

Kreg is a tool-maker with a rich history. They make jigs and accessories used by woodworkers and fabrications. This company has a remarkable track record for producing high-quality tools.

The company was founded by Craig Sommerfield in 1986, who by then was building his home. While building his home, he encountered several challenges that inspired him to start making tools. For example, he could not find a perfect device to connect a face frame to the cabinet carcass. This inspired him to create his first tool, which was named the “Craig’s Jig.”

The tool was a single hole pocket jig. He made it using steel and aluminum. This tool allowed him to work on his home building project with ease. After seeing his ingenuity, his friends and co-workers encouraged him to build more tools. He took up the challenge and produced many jigs. Craig showcased his tools at the many woodworking shows which took place in his locality.

He continued like this for many years until Kreg Tool Company was born. This company has spread its wings to many countries globally, including Australia, the United States, Canada, and the UK.

Ultimate in-depth Kreg k4 review

Dust collection 

As had been mentioned earlier, k4 doesn’t come with a dust collector. This is one of its greatest shortcomings. This means when using this tool, you have to find ways of dealing with the sawdust. And if any material falls to the ground, you must pick it up. If dust is much of an issue to you, wearing a mask would be an option. Otherwise, you can consider using a different tool.

Clamping features 

Thankfully, the k4 comes with a good clamping system that can help you secure the device and the material you are working on. The clamping feature here is well designed to ensure safety in the workshop. Once you secure the tool and the material, you can work without worrying about any slips.

The clamping feature makes it easy for you to secure the tool to the workbench for better machining and cutting. The only issue of concern here is that the K4’s clamping system is external. It is not like the case of k5, which has a built-in clamping system.


K4’s drilling angle is finely tuned to allow for efficient cutting through materials while ensuring that you don’t make any mistakes in the pocket hole size. The drilling angle will ensure the drilled hole is of the correct size. The k4 has a wood-chip relief feature for all its holes. This feature reduces the magnitude of drill holes the user experiences but increases the drill bits’ lifespan.

The device’s clamping mechanism is rear-mounted to help maintain a perfect cutting angle and position, no matter what’s clamped on the jig. The greatest advantage of this device is that it is adjustable to configure it the way you want.


K4 is more affordable than k5. You can spend $100 or less o buy this device, depending on the seller you are buying from. However, the cost should not be the only factor to consider when buying this tool. As stated earlier, you also have to consider the project you have to use it on.

Being that K4 is affordable, you no longer have to do shoddy machining or fabrication work at home.

Dust collection 

The k5 has a dust collector that can swivel on both sides. This dust collector is removable, making it easy to clean this device. After using the device, you can remove the dust collector, empty it, clean the device, and then fix it back in position.

This dust collection feature makes this device safer to use, even for allergic to dust. Most jigs have this feature, but they lack the swivel capability, making k5 be ahead of the pack. The dust collection feature is among the design elements that make k5 to be better than k4.

Clamping features

The greatest advantage of k5 is that it has a built-in clamping system. This makes it easy to get attached to the workbench. With the built-in clamping system, it means you won’t need to buy any extra clamping accessories. You’ll use the existing system to clamp it securely to the workbench. This is unlike the case with k4, which needs extra clamping accessories.


We like about k5 because it allows the user to adjust it to hold the material in a perfect position. It has a ratcheting mechanism that supports this capability. To adjust the device, lift its handle until the device clicks twice. This will show that it is in a stable and secure position. The mechanism also allows the material to slide easily into position.

K5 can handle big pieces of materials, making it the ideal jig for professional material fabrication and woodworking. It features big support wings, which add to its safety and convenience. The wings keep the material being worked on in position for accurate machining. K5 also comes with a storage space where you can keep your screws, drill bits, and other accessories.


The k5 is a little more expensive than the k4, but the difference isn’t that big. You’ll only need to add about $25 to the cost of the k4 to buy a k4. So, a retailer who sells a k4 at $100 should sell k5 at about $125. With that small additional amount, you get a more powerful tool packed with many important features.

The advantage of buying the k5 is that it will serve all your woodwork and fabrication needs. This device comes with a lifetime warranty, meaning once you buy it, you can be sure of having a functional tool for the rest of your life, provided you take good care of it.

Our Thoughts 

K4 and k5 have many advanced and useful features that make them indispensable for any material fabricator or a woodworker. When it comes to choosing between k4 and k4, consider all the factors discussed above.

It won’t help to say that one device is better than the other because each has unique features that make it suitable for a particular use. Both have distinct advantages to technicians who prefer certain methods or styles.

That said, it is important to emphasize that the k5 is a more capable and powerful jig option. However, some users may not need all that power and may find k4 to be more suitable for their job. Our advice is, if k4 can handle your project, there is no need to buy k5, which costs a little more. That would be a waste of money. You only need to buy k5 if k4 can not handle your project.

Professional material fabricators and woodworkers need more powerful devices that can efficiently handle large-scale projects. For this reason, they need k5. On the other hand, individuals who want to perform simple DIY home projects while still wanting to enjoy the functionality and reliability of professional-grade devices can buy the k4. It will suffice.
