What Makes Pocket Hole Joinery So Popular
Walk into any woodworking forum and ask about joinery for beginners. Within minutes, someone will mention the Kreg jig. Pocket hole joinery has become the default starting point for furniture builders because it solves a fundamental problem: how do you join two pieces of wood at a right angle without visible hardware, complex cuts, or years of practice?
The answer is a pocket hole — an angled hole drilled at 15 degrees into one workpiece, then joined to a second piece with a self-tapping screw. The result is a strong, invisible joint that takes about 30 seconds to make. No glue-up time. No clamping for an hour. No dovetail practice.
If you are building your first workbench, shelves, or face frames for cabinets, pocket holes will get you there faster than any other joinery method.
Kreg 720PRO: What You Get in the Box
Retail price: $119-139
The 720PRO is Kreg’s current mid-range jig, sitting between the entry-level Kreg 320 ($49) and the production-grade Foreman ($599). The kit includes:
- The jig body with AutoMaxx clamp (spring-loaded, auto-adjusting)
- Material thickness gauge with detents for 1/2” through 1-1/2” stock
- Drill/driver bit with depth collar and hex wrench
- Starter pack of 100 pocket screws (50 coarse, 50 fine)
- Dust collection port (fits a standard shop vac hose)
- Material support wings for longer boards
The 720PRO’s main upgrade over the 320 is the AutoMaxx clamp. Instead of manually tightening a screw clamp for every hole, you press the board against the jig and the clamp grabs it automatically. Over hundreds of holes, this saves a huge amount of time and wrist fatigue.
Who the 720PRO Is For
The 720PRO is aimed at regular furniture building. It sits between the occasional-use Kreg 320 and the production-grade Foreman. Kreg’s published kit is set up for right-angle joints such as face frames, table aprons, and shelves. This page compares manufacturer specs and owner reviews. We have not used the jig or run strength tests.
What Stands Out
Speed. A pocket hole joint takes 30-45 seconds from drill to screw. A comparable mortise-and-tenon takes 15-20 minutes even with a router jig. For furniture-scale projects where you are making dozens of joints, the time savings are massive.
The AutoMaxx clamp is the real upgrade. On the cheaper Kreg 320, you manually tighten a toggle clamp for every single hole. After 50 holes, your forearm is screaming. The 720PRO’s spring-loaded clamp engages with a press and releases with a lever. It adjusts to different board thicknesses automatically.
Repeatable drilling depth. The thickness gauge has detent positions, so switching between 3/4” plywood and 1-1/2” lumber is a quick adjustment, not a measurement exercise. Every hole comes out at the correct depth.
Dust collection works. The 720PRO has a port that accepts a standard 2-1/2” shop vac hose. Pocket hole drilling produces a lot of chips, and the port is there so a shop vac can collect them. This is not a feature you see on cheaper jigs.
What Could Be Better
Screws are not cheap. The starter pack runs out fast. Budget $30-50 for a box of 500 screws in the sizes you will use most (1-1/4” for 3/4” stock, 2-1/2” for 1-1/2” stock). This is an ongoing cost that Kreg does not emphasize in marketing.
Not invisible on all projects. Pocket holes are hidden on the inside of joints (under tables, inside cabinets). But if both sides of a joint are visible — like the apron of a coffee table — you will see the pocket hole plugs or caps. For those cases, traditional joinery or dowels are cleaner.
The jig only does one hole at a time. The Kreg Foreman ($599) and the 720PRO’s optional docking station allow assembly-line drilling. The base 720PRO requires repositioning for every hole. For a small project this is fine; for building 20 face frames, it slows you down.
Hardwood requires pilot holes in the receiving board. In pine and plywood, self-tapping screws bite perfectly. In hard maple and white oak, the screws sometimes split the receiving board if you skip the pilot hole. This is not a flaw in the jig — it is the nature of hardwood — but Kreg’s marketing suggests pocket holes work in everything without prep.
Kreg 720PRO vs 320 vs Foreman
| Feature | Kreg 320 | 720PRO | Foreman |
|---|---|---|---|
| Price | $49 | $119 | $599 |
| Clamp type | Manual toggle | AutoMaxx (auto) | Pneumatic auto |
| Holes per setup | 1 | 1 | 2 |
| Dust collection | No | Yes | Yes |
| Thickness gauge | Manual | Detent positions | Detent positions |
| Best for | Occasional use | Regular furniture building | Production/cabinet shops |
The 320 is fine if you build one or two projects a year. The 720PRO is the right choice for anyone who builds furniture regularly — the AutoMaxx clamp alone is worth the price difference. The Foreman only makes sense for professional cabinet makers.
Tips for Stronger Pocket Hole Joints
-
Always add wood glue. Apply glue to the mating surfaces, clamp, then drive the screw.
-
Use the right screw thread. Coarse-thread screws for softwood (pine, cedar, plywood). Fine-thread screws for hardwood (oak, maple, walnut). Using fine-thread in softwood strips the hole.
-
Clamp before screwing. A Kreg face clamp or a standard bar clamp holding the joint aligned while you drive the screw prevents the pieces from shifting. This is the difference between tight joints and gaps.
-
Drill pilot holes in hardwood. A quick pilot hole in the receiving board prevents splitting and makes driving easier. Skip this in pine and plywood.
-
For outdoor projects, use stainless steel or exterior screws. Standard zinc pocket screws rust. Kreg sells Blue-Kote and stainless steel screws specifically for outdoor use.
Projects Perfect for Pocket Hole Joinery
- Face frames for kitchen cabinets
- Table aprons attached to legs
- Bookshelves and storage units
- Bed frames and headboards
- Drawer boxes (combined with glue)
- Floating shelves with hidden supports
- Picture frames (with a dedicated angle)
Pocket holes are not ideal for: fine furniture where every surface is visible, joints under extreme lateral stress (like chair legs), or projects where you want zero metal fasteners.
Frequently Asked Questions
Are pocket hole joints strong enough for a dining table?
Yes, for a typical apron-to-leg joint, as long as you use wood glue along with the screws and match the screw length to the stock thickness. We have not measured joint strength, so this page does not quote a load number.
Can I use pocket holes in plywood?
Absolutely. Pocket holes and plywood are a natural combination. Use coarse-thread screws and set the jig to 3/4” thickness for standard plywood. This is how most cabinet carcasses are built in modern woodworking.
Is the Kreg 720PRO worth it over the 320?
If you plan to build more than two or three projects, yes. The AutoMaxx clamp saves time and wrist fatigue on every single hole. Over a 200-hole project, the difference is dramatic. If you only need a jig for one small project, the 320 does the job.
Do pocket holes weaken the wood?
The pocket hole removes a small amount of material. The jig drills the screw at 15 degrees. We have not run strength tests, so this page does not claim the joint is stronger than the surrounding wood.
What size screws do I need?
For 3/4” stock (standard plywood and 1-by lumber): 1-1/4” screws. For 1-1/2” stock (2-by lumber): 2-1/2” screws. For 1/2” stock: 1” screws. Kreg sells variety packs that cover all three sizes.
