Key Features
Overview
The Kreg Easy-Set Stop Collar & Material Thickness Gauge/Hex Wrench Kit, model KPHA330, is a pocket-hole jig accessory kit built for setting drill-bit depth and checking stock thickness when using Kreg joinery systems. This is a pocket-hole jig accessory kit designed for quick pocket-hole drilling setup. If you already use a Kreg pocket-hole jig and need to replace worn setup parts or keep an extra set at the bench, this kit solves a small but important problem: getting repeatable pocket holes without wasting time on setup.
The main value here is speed and consistency. The Easy-Set stop collar uses a viewing window that aligns with the etched markings on the Kreg Easy-Set pocket-hole drill bit. In practical terms, that means you can set bit depth for common material sizes without second-guessing where the collar needs to land. On a job where you’re moving between 1/2 inch face frames, 3/4 inch cabinet parts, and 1-1/2 inch stock, that faster setup helps keep your joinery accurate and your workflow moving.
The included material thickness gauge does more than just measure. It is marked for 1/2 inch, 3/4 inch, and 1-1/2 inch material, and it has a built-in hex wrench for tightening the stop collar. That combination matters because it keeps two setup steps in one compact tool. Instead of digging around for a separate wrench or trying to eyeball material thickness, you can check the stock and lock in the collar with the same piece.
Kreg built this kit as the same style of setup hardware included with its 300-Series pocket-hole jigs, so it makes sense as a direct replacement if the original parts wandered off or got beat up in the shop. The stop collar also fits other standard 3/8 inch diameter Kreg pocket-hole drill bits, which gives it broader usefulness beyond one specific jig. For users with multiple Kreg setups, that kind of carryover is what makes an accessory actually worth keeping around.
Material construction is listed as steel and polypropylene. That is a practical mix for a kit like this. The collar needs the durability and clamping strength of steel, while the gauge/wrench is made to be handled often, tossed in a case, and used for quick setup without adding unnecessary bulk. This is not a flashy accessory, but it is the kind of shop part that makes the whole pocket-hole drilling process less annoying.
Compatibility is another strong point. The Kreg Easy-Set Stop Collar & Material Thickness Gauge/Hex Wrench Kit is made for Kreg Pocket-Hole Jigs, including direct replacement use with the Pocket-Hole Jig 320 and 310. It also works with the K5, K4, K3, R3, Mini, and Foreman DB210, excluding Micro and XL systems. That makes it a smart fit for woodworkers, cabinet installers, trim carpenters, and DIY users who already own standard Kreg pocket-hole equipment and want one reliable setup kit that covers the common material range from 1/2 inch to 1-1/2 inch.
Dial In Pocket-Hole Depth Faster
This kit is all about removing guesswork from pocket-hole joinery setup. When your stop collar and bit depth are set correctly, you spend less time testing on scrap and more time drilling usable holes.
- Stop collar window aligns with etched drill-bit markings for easier depth adjustment
- Designed around the common stock sizes of 1/2 inch, 3/4 inch, and 1-1/2 inch
One Small Tool That Handles Setup
The thickness gauge pulls double duty by measuring material and tightening the collar. That means fewer loose setup pieces to keep track of and a simpler routine when you are switching material sizes.
- Built-in hex wrench tightens the stop collar without needing a separate tool
- Works with standard 3/8 inch diameter Kreg pocket-hole drill bits

Pro Tip
If you bounce between 3/4 inch cabinet parts and 1-1/2 inch stock, keep this kit with your pocket-hole drill bit instead of storing it in a separate drawer. That way your gauge, wrench, and collar stay together, and setup stays consistent from one project to the next.
