Kreg Jig and How to Use a Kreg Jig? 

A Kreg Jig helps to join two wooden pieces together. It is used to drill pocket holes so that the screws can go inside at a predetermined angle. In other woodworking processes, the screw runs through the wood. But unlike other crafts, here the screws enter along with the grain of the wood using the Kreg Jig. It makes the joint much stronger and secure. 

If you are a first-timer, you may feel that it is very complicated to use Kreg Jig. In reality, it is quite the opposite. It may look difficult to learn, but it is surprisingly easy. All you need to do is to measure the piece of wood, set the Kreg Jig to the corresponding width, mark the wood, and drill the perfect pocket holes. 

Kreg Jig R3 VS K4

Kreg manufactures each level of pocket hole jigs. Initially, the first Kreg Jig had only one hole for the drilling. Now the topmost Kreg Jig model has become motorized and so, more convenient. Today, you can get cheaper or the most expensive jigs produced by Kreg. R3 and K4 are precisely in the middle of the game in terms of their features, specifications, and prices. If you are confused between these two models and can’t decide which one is the most suitable for you, let me help you to determine.

R3 – Positives

It has a small size and is versatile. And most importantly, it is very convenient to finish any minor repair jobs such as corner bookshelf or countertops. You don’t need to rush and take your entire wood piece to the shop if you have the handy R3.

K4 – Positives

It can help you to drill through the piles of wood quickly, without compromising its accuracy. Either you are a hobbyist or a professional, this jig is a perfect match for you.

Difference Between Kreg Jig R3 and K4


When it comes to size, it’s a tie between R3 and K4. Both are proving ‘bigger is not always better’ very well. Both are small and portable in size, which makes them super convenient to use. R3 is so tiny that it will fit even in your palm. It looks like a toy and not a tool. So, it is crucial to keep it away from the reach of small children. K4 is a bit larger than the Kreg Jig R3. For the sake of drilling pocket holes only, these machines are perfect. Choose beauty over the beast.


In the category of clamping, K4 wins the race. R3 doesn’t need a work surface. You just have to use a clamp to secure the Kreg Jig directly to the piece you are drilling. While working with the K4, you can clamp it to the surface you want to drill and also use the onboard clamp to secure the workpiece. It gives double protection and perfect accuracy to your project before drilling the holes. Thus, K4 is a more reliable attachment.

Number of Holes

Kreg Jig R3 has two drilling holes, while K4 has three drilling holes. That means you don’t have to move the clamp each time you want to drill the wood. R3 can run up to 1.8 to 2 inches wide, and K4 works best up to 4 inches.

Both of these products are limited to materials having a thickness between 0.5 and 1.5 inches.


R3 and K4 both are made of glass-filled nylon. The hole cores are made of fine, hardened steel. Kreg offers a lifetime warranty on the cores of all the products manufactured by the company.

Wood Chip

Both jigs are equipped with a wood chip relief hole. Such holes help in keeping the drill holes clear at the time of drilling procedures. This way, it also extends the life of your drill bit and makes it durable.


R3 is the older version, and K4 is the latest model produced by Kreg. So, R3 is cheaper than the K4. Kreg Jig K4 has more than double the price than the Kreg Jig R3 pocket hole system.


These are the points that make both the products different than each other. If you ask any experts’ opinions, they would suggest you to start with the Kreg R3 and eventually shift to the Kreg K4. Making pocket holes with a Kreg jig is very easy and safe. Even if you are a beginner, you can learn it within minutes. I personally love to work with K4 because of my rich woodworking experience. So, decide your level of art, learn, and slowly but steadily go further. I hope this article has helped you with all your queries and confusions. Welcome to the joys of wood art.
