The Bottom Line
The Kreg Jig K3 Master System combines benchtop and portable base jigs in one affordable kit, one which we highly recommend.
- Very detailed documentation - Describes numerous uses for pocket joinery
- Once the jig is configured, repeatable pocket joints are easy
- Includes both benchtop and portable bases
- For proper use, proprietary Kreg self-tapping wood screws are necessary
- The nylon screw in the material support stop seems flimsy and could be improved
- The benchtop base and portable base both use the same K3 drill guide block in the kit.
- The K3 Master System includes a dust collection shroud to help keep the guide block clean while drilling.
- The documentation is very comprehensive, but the terminology can be a bit confusing. Take your time when learning the jig.
- Be sure to always set the depth collar on the bit to the appropriate depth to ensure strong pocket joints.
Guide Review - Kreg Jig K3 Pocket Hole System Review
Once you've determined how many holes you'll need to drill, simply clamp the jig to the board in the proper position for the first hole (the instructions for doing so are dependent on whichever base you choose). Set the depth collar on the special 3/8" step drill bit to the appropriate depth and drill the pocket hole. Repeat the steps with the other holes in the head board and remove the jig.
Align the tail board with the head board in the proper position and clamp the two boards together using the included premium face clamp. (This will help ensure that one of the boards doesn't become displaced when inserting the screws.) Then insert the appropriate size of screw through each of the pocket holes and into the tail board.
While glue isn't necessary to hold the joint after the screws join the head board and tail board, glue is recommended to help strengthen the pocket joint long-term.
