Rockler Circle Cutting Jig

Easily cut 10" to 52" perfect circles with your router.

Rating:
90% of 100

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

Rockler Circle Cutting Jig
Awesome product. Very easy to use. Minimal setup and the alignment with the routers in dead on. I had a homemade jig I was using for years, but it just became to sloppy & worn out. Served its purpose though. Exceptional radius capability.

Just buy it.
I’m sure everybody is going to say “I can make that for a dollar” but if you need to get the job done and it fits the router you have just buy it.

Works great, just didn't fit my 2 routers!
This was easy to set up, and cuts a perfect circle with no movement. I used this to cut a 36" drop-leaf table top out of birch, worked perfectly just adjusting depth as I went round. The only complaint is that it didn't fit my Freud or Craftsman routers) - this is not Rockler's fault as they advertised correctly. Luckily my neighbor had a Milwaukee router, which worked perfectly.

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.
What type of bit works best for cutting the initial circle?
Karen A on Dec 22, 2019

Rockler Circle Cutting Jig
Rockler Circle Cutting Jig
Rockler Trim Router Circle Jig
Rockler Trim Router Circle Jig
BEST ANSWER: Item #48871 will not work as it is for a trim or compact router. Item 40982 will if the 7539 router has the black base held on by three screws that are 4" center to center making an equilateral triangle.
Which routers fit this jig best?
A shopper on Aug 17, 2015
BEST ANSWER: I would recommend Porter Cable 690, & 892.
DeWalt 616 & 618
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.
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.
my pin bent, can I just buy a replacement pin?
Bill P on Jul 30, 2016
BEST ANSWER: We have the following parts for this:
# 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?
albe52 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.
Can you cut circles smaller than 10"?
Herman C on Sep 11, 2019
BEST ANSWER: That's a good question, I didn't actually cut the circle, I did it with a band saw and then rounded over the edge with a router bit. I believe you could cut a 10 inch circle depending on the thickness of the piece (mine was very thick piece of mahogany) and some good dexterity. Try it on a piece of scrap.
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
what is it made out of? MDF? Al? Plastic?
Woody on Apr 28, 2020
BEST ANSWER: I am not sure exactly, but it it sturdy and strong. Appears to me to be either solid laminate or covered in laminate material. If it is plastic, it is a rigid, hard plastic.
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

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.
Does this circle cutter fit the Triton TRA001 plunge router?
