What is the difference between Kreg 320, 520, and 720PRO?

The 320 is a basic clamp-on jig. The 520 adds AutoMaxx clamping and improved ergonomics. The 720PRO adds a solid base, docking station compatibility, and the best overall workflow for frequent use. All produce identical pocket holes.

Are pocket hole joints strong enough for furniture?

Yes. When combined with wood glue, Kreg pocket hole joints are more than strong enough for everyday furniture. They handle chairs, tables, beds, and bookcases. For extreme loads, combine with glue and consider the Kreg HD system for larger screws.

What Kreg screws do I need?

Coarse-thread for softwood (pine, cedar, plywood), fine-thread for hardwood (oak, maple, walnut). Washer-head prevents pull-through. Match length to thickness: 1-inch for 1/2-inch stock, 1-1/4 for 3/4-inch, 2-1/2 for 1-1/2-inch.

Specialty Tools

$50-$70 for Kreg 320, $100-$130 for Kreg 520, $140-$170 for Kreg 720PRO, $350-$500 for Kreg Foreman, $40-$60 for Kreg Jig HD.

and screw/plug starter kit.

How to Use

1) Select the correct settings for your material thickness using the Kreg setup chart. 2) Set the drill guide and depth collar. 3) Clamp the workpiece with pocket holes facing the hidden side. 4) Drill pocket holes at high speed using the stepped Kreg bit. 5) Apply wood glue to the joint face. 6) Clamp the pieces together. 7) Drive Kreg pocket hole screws with a square-drive bit. 8) Fill pocket holes with Kreg plugs or caps if visible.

⚠️ Safety Tips

Wear safety glasses when drilling. Clamp workpieces securely. Use the correct screw length for your material thickness — too long will poke through the show face. Drive screws at moderate speed to avoid stripping. Support long workpieces to prevent tipping. Keep hands clear of the drill path.

Maintenance

Clean the drill guides regularly. Replace the stepped drill bit when holes become rough or ragged (every 500-1,000 holes typically). Check the depth collar set screw. Clean the clamp pads. Wax the jig body to prevent corrosion. Replace the driver bit when it wears. Store in the carrying case.

Price Range & Recommendations

Price Range: $50-$70 for Kreg 320, $100-$130 for Kreg 520, $140-$170 for Kreg 720PRO, $350-$500 for Kreg Foreman, $40-$60 for Kreg Jig HD.

Beginners should start with the Kreg 320 ($50) — it handles every pocket hole task and is simple to use. Upgrade to the 720PRO when you want faster workflow and benchtop convenience. The Kreg 520 sits in between with AutoMaxx auto-adjusting clamping. Production shops will benefit from the Kreg Foreman for automated, high-volume drilling.
