Very nice, definitely recomended.
Excellent tool, very tight tolerances make centering a non-issue. Unfortunately tried a cheap knock-off of this jig first and found out what doesn't work. This one does, well worth it.

Building a desk for my Daughter and will need to use a bunch of wooden dowel pins. I needed a way to drill the holes precisely and this seemed to be the best way to go about that. Will update when the desk is done.

looking for a better dowel jig
William C on Oct 11, 2016
SAME AS ABOVE
John F on Aug 28, 2016
Accuracy with Dowels is a must. I am expanding my Workbench and needed to make Dowel holes. I bought a 4' piece of Oak Dowel from HD for $4.00, although my friend did the same thing with his, he used 1/2" metal dowel. (cut each dowel with an Angle Grinder) Extremely strong YES, but will not be able to use any clamps that are affixed to the work area, wood dowels are better.
ROBERT H on Aug 26, 2016

I'm making some cabinets and needed to make the face frames and doors square. The 3/16" drill slot that is included on this jig is perfect for my project. And the other drill slots will work for future projects.
Danny H on Jun 28, 2016
Need to install a couple of old style door knobs that recess 3-4 inches into the door and are 1/2 wide and 4 inches long. Need to drill multiple 1/2 holes centered on the door edge and perpendicular to the door. This jig will work perfectly for that task.

how do you make the jig holes centered?
A shopper on Jul 8, 2015
BEST ANSWER: After tightening the vise, the holes will already be centered along the thickness of the board. If you want to center it along another dimension as well, then you will have to measure and mark the center yourself on the side of the board and then use the markings on the side of the jig to line up the hole you want with your marker.
Can you make it so it doesn't self-center so you can offset the holes a fixed amount? I often put dowels not in the center but in a specific offset from an edge.
Scott R on Apr 15, 2015
BEST ANSWER: Yes, you easily could. Just put - like a 1/4" piece of wood on one side of the piece you're putting the dowel in. That would offset the dowel hole position. You could adjust the amount of offset by the thickness of the "shim" you added into the fixture. I just started using this doweling jig and love it, very well made and accurate. Hope this helps. Roger L.
is there marking pins with it. the metal point things you put in hole you drilled to mark the other part?
george a on Jan 2, 2017
BEST ANSWER: No, there are no marking pins with the jig: it's just the jig itself. Hope this answers your question.

what is included with item # 49221?
Big Fish on Feb 6, 2016
BEST ANSWER: Just the jig, no dowl pins
Did the dowel pins and glue come with the doweling jig?
Steve on Feb 17, 2016
BEST ANSWER: No dowel pins or glue, just the jig and an accurate tool it is.
How do you line up the jig so that holes on both pieces perfectly match? Drill a hole on each piece and use a pin to line up?
Alvin P S on May 7, 2017
BEST ANSWER: I drilled the wholes in my table base. Placed dowel centering pins that Rockler sells. They are pointy. Place table top on base. Lined up my measurements. Tap the top with mallet marking wood. Placed the jig on the the surface to help keep my drill straight. Worked really well. Perfect alignment every time
What is the minimum wood thickness this jig can do? I have a project that is 7/16" stock.
Steve L on Feb 20, 2016
BEST ANSWER: It closes down to just a little under 3/8" so 7/16 should hold tight enough but you can always sandwich the material between two pieces of equal thickness lumber. It just makes marking the alignment a little clumsy but it's certainly do-able. I've used one of these clamps professionally for over twenty years and have done that a few times.
I bought one of these dowel jigs and although I have used it for okay results I have one complaint. The aluminum clamp edge does not line up with the tool steel drill guide. I think these components should line up flush on the edge. It makes it tricky to get repeatable results. Drilling on the edge of a board you can square up the edge with a piece of square material no problem, but when you go to drill the end of a board the tool steel ( black inner part ) is your reference edge but it is a good 16th of an inch difference from the aluminum clamp edge ! making your dowel holes off slightly and one does have to kind of 'eye ball' it to get good results. How do I line up the pieces properly with 2 different edges on the dowel jig? Can you give any instructions ?
Jaysee on Jun 15, 2018
BEST ANSWER: I have bought a couple of these jigs and I am not sure if this is answering your question correctly as I might not understand what you are saying but I did get one that had the guide off center as the holes were not dead center on the jig. I mentioned it to Rockler and they sent me a new one with the Holes lined up correctly. If this doesn't answer it correctly as to your issue, there are thin guidelines on the side of the jig that I use to line up the holes to be drilled and I make a perpendicular line from the hole area I want drilled and line it up with the guides line. Other way to line up, is to site down the hole with a small flash light to see if you are dead nuts on where you are expected to be drilling. Hope this helps!
Is there a metric version of this item?
Kevin W on Jan 28, 2018
BEST ANSWER: IT IS METRIC OR SAE ALL AT THE SAME TIME. ONE SIZE FITS ALL.
What keeps the centre block with the holes in the centre of the stock ?.I bought another brand and I have to place shims on either side of the centre block.
Joseph H on Dec 4, 2017
BEST ANSWER: the block is self centering. It's well made... As you close the tool each side moves to the wood evenly.
How deep on the stock does the jig reach?
JonCatskill on Sep 10, 2017
BEST ANSWER: The depth will be determined by length of your drill bit.The width is 2 1/4”.
need to drill a 4mm hole in posts for wire .do you have small metric drill sizes ?
jonno on Jul 10, 2017
BEST ANSWER: We don't carry a metric dowel jig, sorry
Can miter dowelling be performed with this jig as for picture frame or trim work?
Frank H on Apr 28, 2017
BEST ANSWER: Yes, all that matters is that you line it up accurately and that the stock has parallel sides. There are probably better tools (or jigs) than this for that operation though. I've had mine for 3 years and never used it.
does anyone know where i can get a 3d solidworks model of this component?
Christopher F on Mar 27, 2017
