Rockler Corner Key Doweling Jig

Beautify and strengthen mitered joints using hardwood dowels and other materials!

Item #
88% of 100

Our Corner Key Doweling Jig lets you join mitered corners by running dowels through the joint at 45°. The exposed oval dowel ends result in a unique decorative effect, and the dowels serve to strengthen the joint, much like splines. You can use solid wood dowels in a contrasting species, non-ferrous metal tubes, a combination of both, or even tie the joint together with leather laces. More advanced decorative effects can be achieved by double-drilling to create dowels with a multi-layered core. The jig makes the angled drilling accurate and easy. No other product on the market offers the same functionality, repeatability and convenience. Extended length bits are required.


  • Creates beautiful, decorative mitered joints, and also strengthen mitered corners on boxes, drawers and more
  • Once set, the jig can be easily moved and re-clamped to drill the next hole (clamps sold separately)
  • Precisely molded reference lines and clear alignment window for fast, accurate setups
  • Includes 1/8'', 1/4'' and 3/8'' drill guide assemblies.

Woodworking Experience:
Great jig!
This Jig works great. You can make great dowel corners for another Decorate joint. I love being able to use a light dowel with dark wood and dark dowels with light wood. The effect is very pleasing to the eyes. You do have to make sure where your placement is and tightly clamp the jig before you drill the dowel holes.

Easy setup with professional results.
I used this to insert 1/4" aluminum dowels into the corners of my Bluetooth speaker box. With a backer board, there was zero blow-out. Produced nice crisp joint accents.

Getting a correct piece of MDF is important. Symmetry is much more satisfying. The jig as designed is simple and dependable.

First project with the dowel jig
I purchased the corner dowel jig with an eye to reinforcing 45 deg. miter joints. The decision to purchase was more based on its practical uses rather than aesthetics. However, once I began my first test project, sofa armrest trays, I saw the dowels as a design element. The attached photos show how brass pins were used to not only strengthen the joints, but add a decorative element. The setup and use of the jig was quite straightforward and after a couple of test cuts, I felt quite confident in its use. I have since use it for several projects and am experimenting using mosaic pins. The only "trick" to using it is making sure the thickness setting is correct and the jig is firmly clamped to both sides of the work piece.
1/4 and 1/8 inch brass pins used for corners.  The trays are 12 in. wide and 11 inches long.
The tray is red oak with wenge and leopardwood inserts.  The spaceman in the lower corner approves.

Woodworking Experience:
Good product. May take some practice to operate.
The first box I made didn't work because I was unable to clamp things tight enough and the wood moved while drilling. Make sure you have good clamps and secure tightly. The jig itself is very well made and and easy to use. Will make great joints with tight clamping and attention to detail.

Does it also make straight dowel holes?
Ole N on Oct 24, 2018
BEST ANSWER: This jig is designed to help drill angular dowel holes in box corners.
Does the doweling jig kit comes with a case, I noticed the Doweling Jig w/out drill bits has a case?

Rockler Corner Key Doweling Jig
Rockler Corner Key Doweling Jig
Corner Key Doweling Jig with Set of 3 Drill Bits
Corner Key Doweling Jig with Set of 3 Drill Bits
BEST ANSWER: No case other than the original hard cardboard package. The cardboard is formed to fit the peices within the box, but it is not a plastic case.
Several people intended this for reinforcing picture frames. I'd like it for the same reason, but it looks to me like that would be tough to clamp and neatly accomplish the goal. Have any of you jig owners tried this and how did it go for reinforcing mitered picture frame corners?
SPENCE B on Jan 11, 2019
BEST ANSWER: As the images show it is possible to clamp both sides of the corner. For a picture frame this would work if the outside edges are flat and both sides clamped. Also make sure your backer being used in the jig is new and solid wood... ply tends to fray out with repeated use.
When you have more rockler corner key doweling jig the item# 59517 ?

Do you need to use 6” drill bits or can you use regular bits?
Janis M on Feb 17, 2019
BEST ANSWER: Look at Figure 9 of the instructions that come with this item. It gives a good idea of the length you will be drilling. I would estimate a drill bit at least 5” long for 3/4” thick pieces is required. If the pieces are very thin, like 1/4” or 3/8” you could use a shorter bit - such as 4 1/2”.
I just bought this. But how does one find or make precisely sized dowels? I have plenty of exotic woods and would like to use them for making dowels for this jig. I have the Lee Valley Dowel Master. Expensive and difficult to make smooth precise dowels. Any help will be greatly appreciated.
Fred H on May 27, 2020
BEST ANSWER: There are only two other ways I know to make dowels. One is to use a lathe if you have one. The second is to use dowel dies and example of which is the Woodpecker Dowel Press (expensive) or the Lie-Nielsen Dowel Plate (much more affordable). The dies will leave a smooth and very precise dowel.
Why is the use of brad-point drills not recommended?
Brian S on Feb 18, 2020
BEST ANSWER: I assume it is because the steel bushing guides the drill bit, so a brad point isn't needed. I used a regular drill bit when I corner keyed an Oak rolling base I built. The base was 3" square Oak, so I needed a long drill bit to get all the way through the corner. Doweling across the corner made it very strong.
Could you do a box that is 15 inches deep?
Cliff S on Jun 14, 2019
BEST ANSWER: It makes no difference how deep or how large the box is however it can make a difference in the thickness of the walls of the box as that would determine the length of drill and dowels you would need. The deeper the box the more dowels you may want to use.
I am an artist and make my own frames from 1x2. Would this work instead of using nails and the air compressor? I usually use 18 gauge brads and nail two on one side and one on the other side of the mitered corner. Thanks.
martha s on Feb 18, 2020
BEST ANSWER: Martha, Yes this will work great on you 1x2 wood, i use it on 3/4" teak that i use in my tackel boxes, follow the direction when setting it up for you wood and you will be super happy, Mike
Three questions actually; 1.) What is the RED clip's function? 2.) Does this jig require the use of backer boards, (the vertical board in the pictures.) If so, why? Shortcomings of the initial design? 3.) Would using either a brad point drill or a Kreg drill help with the tear-out on the hole? Thank you in advance for your time.
Dorald on Feb 9, 2020
BEST ANSWER: 1. The red clip is the locking key to hold the bushing in place.
2. Yes you need a backing board. You need it for the spacing and to prevent tear out. Since the bit is coming through at an angle, it tears out even with brad point bits if you don't have a backer.
I make gift boxes. Seldom are the sides greater than 3/8” thick. Usually a bit less. Will it work?
Lynn D on Feb 6, 2019
BEST ANSWER: Yes, you would use the 1/8" drill (get a longer one than normal) and 1/8" dowels. I have used it with 1/4" mitered sides.
Can the jig handle corners that are not 90 degrees? Like a 45 degree angle on a flag case?
Ken K on Jan 11, 2019
BEST ANSWER: No. It is designed to accomodate only 90 degree corners. You wd have to make another drill bit guide then the metal one included. That is what I received in the box.
Are all 4 corners glued up and allowed to dry and then drilled for the dowels or are they drilled for the dowels and then glued up?
Rich on Jan 8, 2019
BEST ANSWER: All 4 corners are allowed to dry first. Then drill for the dowels. Please let me know how it works for you. Definitely try on scrap wood first. I had trouble getting it to drill straight.

Dirk H on Feb 18, 2020
BEST ANSWER: No, 1/8 1/4 and 3/8. Wish they made 3/16 and 1/2".
Can you use it to strengthen plywood cabinets?
Cory H on Apr 20, 2019
BEST ANSWER: I might help but very little. It’s really for decoration on boxes etc. I had a hard time drilling straight thru corners.i sent it back but maybe it was me and not the jig.
Will the corner jig als work on butt joints?
Jack H on Dec 26, 2018
BEST ANSWER: You can use it on butt joints but symmetry will not be achieved. It may be you’ll end up drilling from both sides.
What wood thickness can it be used on? 1/2”, 5/8”, 3/4”, 1” or greater?
John L on Dec 9, 2018
BEST ANSWER: All of the above. But I ha$ trouble centering the jig. Bsometimes it would not drill where I wanted to go. Sometimes it works ok. Just practice on scrap first
Can you use this on 4x4 lumber?
Cynthia H on Jun 17, 2020
BEST ANSWER: The scale is only graduated up to 0.75". You could use it on a 4x4 but dowel would be close to the edge of the lumber.
Can the jig be configured to do inside corners? I have a manufactured drawer for a dresser that is badly made with dove tails.. they don't match up and little or no room to fix but this might be the answer.
Dave on Dec 4, 2019
BEST ANSWER: No it can only be used on the outside corners.
how far can you drill the hole from the edge of the workpiece?
Michael T on Sep 18, 2019
Rockler Corner Key Doweling Jig
Rockler Corner Key Doweling Jig
Corner Key Doweling Jig with Set of 3 Drill Bits
Corner Key Doweling Jig with Set of 3 Drill Bits
BEST ANSWER: The farthest that you can set it for is with the 3/4 inch setting. The drill the centers about 3/4 inch from the tip of the miter and goes through at a 45 degree angle.
