1. A Drill Guide With 3 Holes

This drill guide helps you to drill perfect pocket holes on the materials. You can drill holes with an increment of 0.125” from the hole dimension 0.5” to 1.5”. This drill guide is made of plastic and the core in hardened steel. This steel core supports the work piece to make precise holes.

2. The Toggle Clamp

This toggle clamp is one of the most important features of this tool. It helps you to hold the workpiece firmly so the material doesn’t move while drilling hole in it. Adjusting the clamp with the workpiece thickness is super easy; you can adjust it by rotating the required settings and use the locknut to lock it.

3. Jig Clamping

You can clamp the jig on any workbench by using C-clamp or Kreg’s multipurpose clamp. This large clamping recess helps the jig to remain in place while drilling holes by using the drill guide.

4. Drilling Angle

The drill bit’s driving efficiency increases due to the optimized drilling angle. This drilling angle helps to drill quality pocket holes.

5. The Depth Stop

The drill bit comes with a depth stop or collar so you can set it up to drill the hole to a correct depth.

6. Wood Chip Relief

While drilling a wood piece it started creating wood chips. To remove the accumulation of the wood chip the tool comes with a wood chip relief. It helps you to drill a perfect pocket hole and also increases the lifespan of the drill bit.

1. Ratcheting Clamp

As compared to K4 it comes with an easy clamping system to clamp the workpiece. It has a ratcheting clamp which can be adjusted by sliding with respect to the material thickness. Once the ratcheting clamp sets against the workpiece then you need to lift the handle until two clicks.

2. Mount Handle

In K4 there is a back mount handle, which is okay to use. But the front mount handle in K5 makes the clamping easier and faster.

3. Support Wings

The K4 has a drawback of not supporting large workpieces. The K5 addressed this problem by attaching large support wings on both sides of the jig. There is a smart design involved with these large support wings that they have storage compartments for drill bits, screws and other accessories.

4. Dust Collector

The K4 has a rigid dust collector which can’t be swivel. This issue has fixed with K5, it has a swiveling port can be rotated to to adjust the position so you can easily attach the vacuum hose with it.

We have already discussed the K4 features and the enhanced features of K5. Which itself draws lines between these two tools but let me summarize the differences.

What are the differences between K4 & K5?

Kreg K4 vs K5


Both jigs have two clamps one to hold the workpiece and another to hold on the work surface. K5 comes with a built-in clamping system to attach on the work surface where with K4 you have to provide your own clamping system.

In terms of clamping the workpiece K5 comes with a ratcheting clamp which is easier and convenient to clamp the workpiece as compared to K4. K5 wins in the clamping race.

Support & Storage:

As discussed earlier the K5 has a smarter design over the K4. The K5 comes with two wings or storage boxes which support larger workpieces as well as helps to store other accessories of the jig.

Dust Collection:

Both K4 and K5 have dust collection ports but K5 has a swiveling port which you can rotate to adjust to connect with the vacuum hose, on the other hand K4 has a rigid port. This feature of K5 is appealing but there are few customers who have reported that due to the hose weight it decouples with the port and the dust falls on the work floor. But this minor issue could be fixed with a duct tape.


Both K4 & K5 have equal performance even though K5 has more features which makes the wood worker’s life easy. But when considering larger wood pieces K5 produces better pocket holes thanks to its larger supported wings. 


You guessed it right, the successor K5 is pricier than K4 due to the extra innovative features, which makes it one of the convenient tools to use for pocket holes drilling.
