    What Are the Differences Between Them?

    Performance

    Edge: Kreg K4

    If you’re looking for the overall, better option, the Kreg K4 is the one you should get. It is larger, so it can be used in more applications. It comes with many different accessories and has 3 drilling holes. It clamps quite easily as well, which just makes it more straightforward to use.

    The Kreg R3 isn’t a bad option. It just doesn’t have as many features and isn’t nearly as professional as the Kreg K4. For this reason, we had to give the K4 the win in this category.

    Cost

    Edge: Kreg R3

    This is where the Kreg R3 really shines. It is very inexpensive. You get a lot of bang for your buck when you purchase this model. If you’re on a budget, you aren’t going to find anything better than this.

    Of course, these tools really aren’t that expensive to begin with. You aren’t going to be taking out a loan to purchase one. Still, if you really need to stick to a budget, then the Kreg R3 is your best bet.

    Size

    Edge: Kreg R3

    The Kreg R3 fits in the palm of your hand. There is a reason it is labeled as a “pocket” jig. It is just so much smaller than other options on the market. If you’re looking for portability, it doesn’t get much better than the Kreg R3. It is so much smaller than most options on the market. We really consider it the best option for those who need a tool that can travel.

    At the same time, the K4 is larger for a reason. Much of the size comes from the on-board clamp, which is a must-have feature in some situations. Bigger isn’t automatically worse, but it is something to consider if you need a portable tool.
