Kreg K4 Project Kit with 20V Drill: What You Actually Get

A practical look at the Kreg K4 Project Kit with the 20V Ionic Drive drill: what's in the box, who it suits, and when a bare K4 or 720PRO makes more sense.
Quick answer
The Kreg K4 Project Kit bundles a K4 pocket-hole jig with a 20V Ionic Drive compact drill, so you get the jig and the driving tool in one purchase. Buy it if you are starting from zero and want one box that covers drilling and driving. If you already own a capable drill, the bare K4 or the 720PRO is the better value.
What the K4 Project Kit actually contains
The kit pairs the Kreg Pocket-Hole Jig K4 with a 20V Ionic Drive 1/2-inch compact drill. The K4 side gives you a customizable setup for materials from 1/2 inch to 1 1/2 inches thick, an industrial-grade toggle clamp, a built-in guide for quick pocket-hole drill bit setup, and onboard storage that keeps drill and driver bits close at hand. The drill side is a brushless compact model, which matters for runtime and control when you are driving pocket screws.
The practical result is a single purchase that covers the two jobs every pocket-hole project needs: boring the angled hole and driving the screw. You are not hunting for a separate drill or hoping your existing one has the right chuck and power.
How the K4 jig handles real projects
The K4 is the time-tested design: you set the drill bit and stop collar using the built-in guide, clamp the workpiece with the toggle clamp, and drill. Wood-chip relief holes keep the drill bit clear of excess debris, which reduces the need to stop and clear shavings mid-hole. The impact-resistant polymer body and lifetime drill guide warranty mean the jig is built to survive a garage or shop environment.
The tradeoff versus the 720PRO is setup speed. The K4 requires you to set thickness and bit depth yourself; the 720PRO's Automaxx dual-action clamping automatically clamps and adjusts to the proper material thickness. If you switch between 3/4-inch plywood and 1 1/2-inch stock often, that automation saves real time. If you mostly build with one or two thicknesses, the K4's manual setup is not a burden.
Where the 20V drill fits in
A pocket-hole project needs a drill that can spin a pocket-hole bit cleanly and then drive screws without stripping. The included 20V Ionic Drive compact drill is brushless, which generally means more efficient power delivery and longer runtime per charge than a brushed motor of similar size. Its 1/2-inch chuck accepts standard pocket-hole bits and driver bits.
If you already own a brushless drill with a 1/2-inch chuck, the drill in this kit is redundant. That is the single biggest reason to skip the bundle and buy the jig alone.
The beginner path: pair the kit with a project
If you are buying this kit as your first pocket-hole setup, the fastest way to confirm it was the right call is to build something with precut parts. The Kreg Woodworking Kit for Cornhole Boards includes precut 3/4-inch plywood pieces for two boards and detailed assembly instructions, and it is designed for beginners building woodworking skills. You use your pocket-hole jig to create the joints, then drill and drive. Because the parts are already cut, you spend your first session learning the jig and drill rather than measuring and ripping stock.
That combination — this kit plus a precut project — is the lowest-friction way to find out whether pocket-hole joinery fits how you like to work.
Decision rules: which version to buy
- Buy the K4 Project Kit if you own no drill: You get the K4 jig plus a brushless 20V compact drill in one order, so there is no gap between buying the jig and being able to use it. Best first purchase for a true beginner.
- Buy the bare K4 if you already own a 1/2-inch drill: The jig does the pocket-hole work; a second drill adds cost without adding capability you do not already have. Skip the bundle and put the savings toward screws or a project kit.
- Step up to the 720PRO if you change material thickness often: Automaxx clamping adjusts to material thickness automatically, which removes the manual setup step that the K4 requires each time thickness changes. Choose the 720PRO when speed of repeat setup matters more than entry price.
- Add a precut project if this is your first jig: A kit with precut parts and assembly instructions lets you practice the drill-drive sequence on real joints before you cut your own stock. Pair the kit with the cornhole board woodworking kit to learn on a finished project.
Key product facts
- Kreg® Pocket-Hole Jig K4 + 20V Ionic Drive™ 1/2" Compact Drill Project Kit: Bundles the Kreg Pocket-Hole Jig K4 with a 20V Ionic Drive 1/2-inch compact drill featuring a brushless motor. One purchase covers both boring pocket holes and driving screws, so a true beginner does not need a separate drill.
- Pocket-Hole Jig K4: Customizable setup for materials from 13 mm to 38 mm thick in 3 mm increments, with an industrial-grade toggle clamp and built-in drill bit setup guide. You can dial the jig to common sheet goods and solid stock without guessing, and the clamp holds the workpiece while you drill.
- Pocket-Hole Jig 720PRO: Automaxx dual-action clamping automatically clamps and adjusts to the proper material thickness, with a GripMaxx anti-slip clamping surface. If you frequently change material thickness, the 720PRO removes the manual setup step the K4 requires.
Who this kit fits
Best for
- Beginners who do not yet own a drill and want one purchase that covers the whole pocket-hole process
- DIYers building cabinets, shelving, or shop projects in 1/2-inch to 1 1/2-inch material
- Anyone who wants a proven jig design with a lifetime drill guide warranty and onboard bit storage
Not for
- Woodworkers who already own a brushless 1/2-inch drill and would be paying twice for the same capability
- High-volume builders who switch material thickness constantly and would benefit from the 720PRO's automatic clamping
- Anyone who needs a jig for material thicker than 1 1/2 inches, which this jig is not set up for
