The Kreg Pocket-Hole Jig Expansion Pack is an add-on accessory for Kreg pocket-hole joinery systems, built for woodworkers who want more drilling capacity and more spacing flexibility from the same jig. This is a pocket-hole jig accessory designed for expanding hole-drilling and spacing options on Kreg Pocket-Hole Jig 310 and 320 systems. Model Number: KPHA110.

What matters here is simple: this pack lets you add another hardened-steel drill guide and a spacer to your existing setup. On the bench, that means you can drill additional pocket holes without resetting as often, and you can fine-tune hole spacing for different workpieces. If you're building face frames, boxes, cabinets, shop fixtures, or basic household projects, that extra flexibility saves time and helps joints land where you want them.

Kreg built this expansion pack around the same straightforward setup that makes the 310 and 320 jigs popular in the first place. The drill guide includes material-thickness stops for 1/2 in., 3/4 in., and 1-1/2 in. stock, which covers a lot of the common material used in DIY and light professional woodworking. Instead of working around a fixed layout, you can adapt the jig to the board in front of you and keep moving.

The construction is meant for repeated use, with a nylon body and hardened-steel drill guide where it counts. That combination matters because the body stays light and easy to handle, while the guide surface is built to hold up to repeated drilling. For an accessory like this, durability matters more than flash, and Kreg clearly designed it as a real shop add-on rather than a one-project extra.

Compatibility is the whole story with this product. The Kreg Pocket-Hole Jig Expansion Pack is made specifically for the Kreg Pocket-Hole Jig 310 and Kreg Pocket-Hole Jig 320. You can use it to add a second guide to a 310 or a third guide to a 320. The included spacer works with both jigs, giving you additional layout options without switching to a different system.

This is a smart buy for anyone who already owns a Kreg 310 or 320 and finds themselves wanting faster pocket-hole drilling or better spacing control. If you do occasional repairs, home projects, or regular woodworking, it is a practical upgrade. If you do not own a compatible Kreg jig yet, this is not the place to start, because it is an expansion pack, not a standalone jig system.
