Rockler Circle Cutting Jig

Cut flawless circles from 10" to 52" in diameter without complicated math equations! The Rockler Circle Cutting Jig sets up in minutes and mounts quickly to many popular routers made by Porter Cable, Makita, Hitachi, DeWalt, and Bosch. Or, easily drill your own holes to custom fit any router. Includes two center pivot pins which are used as a pivot point to rout perfectly arced circles (one pin is used for soft woods, use the other if your design allows drilling a center hole). A recessed groove in the jig lets you slide the center pivot pin (your center point) up or down the length of the jig to find the correct, exact diameter of your circle. Use the 4-star knob to tighten the T-bolt with the center pivot pin installed and you're ready to go!


Fits the following Routers:

Porter Cable 100, 690, 890, 7529, 8529
Makita 1100 Series
Hitachi M12VC
Dewalt DW616, DW618, DW625
Bosch 1617 Series, 1618 Series, 1619 and 1619 EVS

  • This item is not predrilled for the Bosch Plunge Base.

Really easy to use
If you need to cut a nearly perfect circle into wood, buy this device (yes, you can make your own, but it's just not worth the aggravation). It connects to most 6" diameter routers. I used this on an old Sears Craftsman router and the holes did not line up. That required drilling 3 holes into the jig and counter-sinking them, a minor, one time inconvenience. But it will fit most Porter-Cable and Bosch router bases. It comes with 2 pivot pins, a sharp pointed pin for cutting the top surface and a rounded 1/8" diameter 3/8" long pin for cutting the underneath surface (you would need to drill a 1/8" hole for that). The threads are left-handed so that the pin will not unscrew as your router moves counter-clockwise. Make sure that you do not cut into your workbench! If you do not cut all the way through (most router bits are not long enough), you can finish the circle with a flush-trim bit with the bearing located on the router side of the bit. I used a 1/4" straight bit followed by a 1/2" flush-trim. Be aware that router bits don't like grain changes and as you go around, the bit can grab and chew up the wood on the perpendicular grain sections. One last suggestion: When mounting the router onto the jig, make sure that the power switch will be within easy reach and the discharge port is away from you.

Small adjustment for excellent results!
Had to drill new pilot holes for my festool router. But it was no big deal and worked like a dream after that small adjustment. Used to cut a 53" circle dinning table for client. Was extremely pleased with the results!

Circle Cutting Jig
I used this to square-up square-up the edge on a 34" coffee table top before applying new edge banding. It worked really well.

It comes with a pivot pin that would go into a drilled hole on the underside of the workpiece if you're preserving the show surface, or as an alternative, a pivot point if you need to work from on top. Since I'll be applying new laminate, I drilled a 1/8" hole for the pin in the top & filled it afterwards. I'm sure I'd have to practice a while before I felt comfortable using the pivot point

To use it, I loosened the center knob a little, then started the router & brought it in until it kissed the edge, then held it with one hand & tightens the knob with the other - easy peasy. It took 4 passes to clean it up entirely, but I had to stop after each pass to un-wrap my extension cord.

As advertised
Was between this jig and a bandsaw circle cutting jig. Bandsaw jig showed mixed reviews and was more expensive. My concern with this jig was how well the "anchor" portion of the jig work. I've used it half a dozen times and it has worked just as advertised, no issues.

Hi. I'm new to woodworking and I am wondering how do you secure the pivot point if you are cutting a circle out. I'm making cat cubes and the pivot will be on the piece I'm cutting out. I'm using cookies to raise the wood. Do I secure the pivot by using a board below the piece I'm cutting? Thanks!
A shopper on May 19, 2015
BEST ANSWER: I use a backer board under the piece I am cutting. That everything stays stable and you don't cut into your bench.
Will this fit a PC 7539 plunge router?

Rockler Circle Cutting Jig
Rockler Circle Cutting Jig
Rockler Trim Router Circle Jig
Rockler Trim Router Circle Jig

Which routers fit this jig best?
A shopper on Aug 17, 2015
BEST ANSWER: I would recommend Porter Cable 690, & 892.
DeWalt 616 & 618
Will my Black & Decker EVS plunge router fit the base of the circle cutter guide. My router base is 6 inches wide?
Patrick W on Sep 15, 2016
BEST ANSWER: I have a dewalt plunge router that I use, the pre-set mount holes didn't line up, so I drilled my own holes with out much difficulty, so you should be able to do the same with your black and decker plunge router.
Moved recently and lost the hardware kit with bushings, pins, and bolts. etc. Can I purchase this entire kit separately?
Kim P on Feb 6, 2017
BEST ANSWER: Not sure about the purchase from Rockler, but your local big box store should have the locking bolt and small washers. You can use a finish nail for the pivot pin. Get a small bolt and drill a hole into the threaded end, trim the finish nail to the right length, and glue the nail into the hole you drilled with GOOP or that 6000 glue.
my pin bent, can I just buy a replacement pin?
Bill P on Jul 30, 2016

# 50741 pointed point - $2.99
#59802 round point - $2.99
These can be order through our customer care team at 800-376-7856.
After determining the diameter of the hole to be cut do you drill a hole at some point for the router bit to start in?
al b on Feb 8, 2017
BEST ANSWER: I probably wouldn't drill a hole since I use a plunge base on my router. Unless you are cutting a thin piece of material you will generally make several passes with the router each pass being a bit deeper than the previous. Don't try to cut 3/4" material in a single pass. If you are not using a plunge router then I would probably just lift/bend the router jig a slight bit and then lower the jig and router into the material.
I don't have a compact router and looking for a circle jig for it?
Beau S on Jul 31, 2017
BEST ANSWER: This circle cutting jig requires a standard router. I believe Rockler has a jig made for a compact router.
Does this kit come with mounting hardware for the router, like the trim router circle jig?
TrippG on Feb 19, 2016
BEST ANSWER: I have both the 36" and 52" jigs and both allow the removal of the router base and bolt patterns in the jics to bolt the jig directly to the router in place of the router base.
Are the pivot pins included with the jig?
HD S on Aug 13, 2015
BEST ANSWER: Yes, both a sharp point and blunt version for pre drilled pivot.
For cutting circles out of 3/4 inch plywood, what bit do you recommend? (I am fairly inexperienced at routing.)
Matt G on Nov 23, 2016
BEST ANSWER: Any simple straight bit will do fine. Smaller bits are easier to control so I typically use 1/4 inch. I recommend doing the cut in 3 passes. Start with a shallow 1/4 inch depth cut, vacuum out the cut, then set the depth 1/2 inch, cut and clean again, then make your final cut at full depth.
Hi what's the thickness of the jig? thanks
Gavin S on Jan 28, 2017
BEST ANSWER: I'm about 600 miles away from the jig but I'd guess 1/4".
Can I cut a 7" circle with the 40982 jig ?
Roy M on Sep 19, 2016
BEST ANSWER: I measured the jig and 10 inches in diameter looks to be the smallest you could make.
What is the smallest diameter I can cut?
Brenda D on May 1, 2016
BEST ANSWER: Minimum adjustable distance for the trim router circle jig is 4 ¾ inches to the center of the router bit.
will it fit a Porter Cable model 6931?
Bill P on Mar 7, 2016
BEST ANSWER: Sorry but i don't know. I have a Bosch router and I had to drill my own holes to mount it. Not a big obstacle but who knows why they didn't try to make the mounting holes more universal. I knew this going in and still bought the jig as it was still the best option I could find for cuttin a big circle (51") for a table top. Worked like a charm.
What is the best router bit to use on the circle jig when cutting into 3/4" hardwoods?
Donald on May 16, 2015
BEST ANSWER: You need to use a straight cutting bit. 1/4" or 3/8" is fine but the key is to make a few shallow cuts rather than trying to cut all the way through in one pass. Depending on the hardwood, I'd only go about 1/8" at a time so you don't burn out the bit. Hope that helps, Dave
Will my Ridgid model R2401 work with this circle cutting jig?
Bob D on Nov 14, 2018
BEST ANSWER: Not completely sure. But it has multiple mounting arrangements to fit a large variety of routers
Can you extend the diameter of the jig to allow for a larger diameter than the jig claims to cut?
Kari B on Jul 4, 2018
BEST ANSWER: You need a jig stretcher to do this, I think they are only available to Canadians.
Has anyone had issues with getting center pins to thread in to t bolt?
Thomas P on Mar 25, 2018
BEST ANSWER: I had trouble with mine falling out.
Is this Jig fits to my makita 1-1/4 Hp 6.5 Amp Compact VS Router / RT0701C router?
chris on Dec 22, 2016
BEST ANSWER: Really do not know, but when I bought this jig it did not fit my router so I drilled the plate to fit it. It took very little time and works great now!
Are the screws right hand thread or left hand thread?
kb2hpr on Apr 24, 2016
BEST ANSWER: The screws needed are your screws that hold the router's base plate. The circle cutter temporarily replaces the base plate using your screws.
Is the Rockler circle cutter jig pre drilled for a Festool OF1400 router?
Dave R on Jan 9, 2016
BEST ANSWER: No, it is not, but it is easy to drill holes to fit the OF 1400. I was very pleased with the results and used it to cut a 38" circle for the top of a coffee table.
Is the t-bolt with threaded hole (for the center pin) available separately? I can only find t-bolts without the hole in the shaft

Greg S on Oct 10, 2017
BEST ANSWER: No, routers are sold seperately
What's the diameter of the hole where the router bit goes through? I'd prefer to use a guide bushing to save time on setup.
BallerDude3 on Dec 11, 2016
BEST ANSWER: The diameter of the hole where the router bit goes through, at least on my version of this circle cutting jig (purchased in late 2016), is 1-1/2" (+/- 1/64").
