Projects That You Can Use Kreg K4 or Kreg K5 For

Pergola Rafter

Kreg K4 VS Kreg K5:

Pergolas are a wonderful addition to the backyard. Maybe you’ll want to save the cost of hiring someone to build it, so you decide to do it yourself. It’s clear that you don’t want to use brackets so you can use either a Kreg K4 or K5 to drill two holes at the end of the end of the board. You’ll want to use one hand to hold the jig down firmly or have someone help you as the jig will likely kick out. You’ll do 1” inch on each side of the board, then you’ll use the clamp to hold the board in place. You’ll then put in your screws and repeat on the other side of the board, with the clamp on the other side as well. After that, you’re done using the jig for the rafter.

Wooden Toy Box

Kreg K4 VS Kreg K5:

For this project, you’ll likely use the Kreg K4 as you’ll be dealing with smaller pieces of wood. You’ll want to set the measurement on the jig, so that it can make the hole precisely. You’ll then want to drill ¾” holes four times (two per side). You will then measure again and mark at least five pocket holes. You’ll want to do this again for another piece of wood for the toybox. You will then use the jigsaw to cut the straight lines and continue until you’re done.

Gobble Gobble Wood Sign

Kreg K4 VS Kreg K5:

You will likely want to use the Kreg K5 for this project. You’ll want to mark the areas where you will be making holes on the rectangular board and drill 3-4 pocket holes near the longer edge. You can do the same for the other boards, where you’ll use it for connecting at a later time in the project.

Industrial Rolling Cart

Kreg K4 VS Kreg K5:

For this project, you’ll want to use the smaller Kreg K4. You start by paring up six ⅛ wood pieces into three pairings of the two board shelves. Then you’ll use the jig to start making pocket holes, 4 of them, on the long side of the board, per pair. You’ll repeat the same for the rest of the pairs.

Storage Bench

Kreg K4 VS Kreg K5:

For this project, you can use either Kreg K4 or Kreg K5. You’ll want to make sure that it’s spaced apart on 4 feet boards, like 6-8 inches. Then you can make your pocket holes and repeat per pair until it’s done.


Both Kreg K4 and Kreg K5 are good jigs that are worthy of being in a wood workshop. Both have features that are beneficial to each user. Whether you need something small or something larger, you’ll need to decide which one is best for making pocket holes. Obviously, the Kreg K5 comes with more features and an onboard storage/dust collector.

If we had to pick between the two, we love the Kreg K5 Jig. It has more features, a built-in clamping system, storage and a dust collector. It can help get precise pocket holes, which is what we like, and it lets you adjust the thickness.
