Kreg Tool 3/8-in. High Speed Steel Custom Plug Cutting Bit for Pocket-Hole Joinery (KPC1020)

The Kreg Tool Custom Plug Cutting Bit KPC1020 is a specialty drill bit built for making custom wood plugs that fit standard-size Kreg Jig pocket holes. This is a plug cutting bit designed for pocket-hole joinery and finish-ready plug making. Model Number: KPC1020. If you want pocket-hole plugs that match the wood species and grain in your project, this bit is the part that makes that happen.

Instead of relying on pre-made plugs that may not match the stock you are working with, this bit lets you cut your own. That matters when you are building furniture, cabinets, trim work, or visible pocket-hole projects where the repair needs to blend in. The bit works with the Custom Plug Cutter Drill Guide Kit and produces the correct diameter for standard Kreg Jig pocket holes.

Kreg built this plug cutter bit with a positive stop collar to control drilling depth. In real use, that helps you make more accurate plugs without constantly checking depth by hand. The open design and enlarged inside diameter also give the plug more clearance as it forms, which makes drilling easier and helps reduce binding during the cut.

The cutting geometry is what separates this from a basic accessory. Special fluting helps reduce heat and friction, which can improve cut quality and extend bit life, especially if you are making multiple plugs in one session. The multi-tooth cutting tip is designed to shear cleanly, so the plugs come out smoother and more consistent, which means less cleanup before glue-up.

On the setup side, the Kreg Tool Custom Plug Cutting Bit chucks into any drill, so you are not tied to a dedicated machine. That makes it easy to integrate into an existing woodworking setup. At the same time, it is not a general-purpose drill bit. It is a purpose-built pocket-hole accessory intended to work with the hardened-steel drill guide in the matching plug cutter system.

This bit is a strong fit for woodworkers, cabinet installers, trim carpenters, and serious DIY users who want cleaner-looking pocket-hole joinery. If your projects leave fasteners exposed in visible areas and you care about the finished look, cutting your own matching plugs is the better move. If you just need raw speed and do not care about appearance, pre-made plugs may be enough. But if you want the repair to disappear into the project, this is the right accessory to keep on hand.
