Rockler Trim Router Circle Jig

Item #
90% of 100
Our new Trim Router Circle Jig allows you to use the new crop of compact, plunge-style trim routers to cut circles from 6" to 36" in diameter! Compact and lightweight, it's the ideal jig to use in small shops or on the jobsite. It sets up in minutes, and is predrilled to mount to popular trim routers from Porter Cable, DeWalt, and Bosch. And since it's made of 1/4" phenolic, you can easily drill holes to fit any router. Includes two center pivot pins for routing perfect circles: one sharp one, which is used for soft woods, and one blunt one, which is used if your design allows for drilling a center hole. A routed channel in the jig lets you slide the center pivot pin up or down the length of the jig to match the 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 rout!

  • Helps you cut flawless circles
  • Fast, easy math-free setup
  • Fully adjustable, slide the center pivot pin up or down the length of the jig to rout circles from 6" to 36" in diameter
  • Features a tough, long-lasting 1/4" phenolic core
  • Includes two center pivot pins for different routing applications (one has a sharp point for holding steady in soft wood, use the other if you're willing to drill a center hole)
  • Includes a T-bolt with 4-star tightening knob to tighten the center pivot pin to the jig for worry-free, no-slip routing
  • Includes hardware to mount any one of a variety of routers to the jig

Predrilled for the following routers:

  • DeWalt DWP611PK
  • Porter-Cable 450PK
  • Bosch Colt PR20EVSPK

Router Jig
Love the router Jig. I got it for my crummy ryobi router which doesn't fit the pre drilled holes that come on this but it was easy enough to drill new holes through the material. It is sturdy and beat my old method of a scrap piece of wood I used.

Are these made out of metal or plastic?
Daniel L on May 3, 2016
BEST ANSWER: As it says in the specifications above "Features a tough, long-lasting 1/4" phenolic core." Phenolic is a hardened resin. Many circuit cards are made from this material.
How do you attach this to the DEWALT trim router? I have tried but can't figure it out. Any help is appreciated!
Nicholas S on Jun 28, 2016
BEST ANSWER: I don't have a Dewalt trim router. I have a Bousch Trim Router what you could do is what I did. Taking off the base plate and making one out of a piece of !/4" masonite to attach to the circle maker. granted I have only used it 3 times with the temporary base but it worked out well just need make sure the temporary base is secured to the router and then to the circle maker
Will it work on Craftsman 320.28212 Palm Router?
Frederick M B on May 5, 2016
BEST ANSWER: It depends on the hole pattern for your router base plate.
You can check this out on Rockler.com under item #48871.
Down the right hand side of that page there is a hole pattern PDF page under the Technical Download header.
what diameter is the center pin? Are the tread all the way which I prefer they are not going thru the material I'll be using!
Ron on Nov 1, 2015
BEST ANSWER: There are two pins one is about 3/16 with a rounded bottom that will go in the center to make your circle. This pin is use if you plan to make the whole larger like for a umbrella or lazy Susan. The other pin has a very sharp point and leaves a whole the size of a #17 brad. Both are threaded about a quarter inch above the point that goes into the locking screw. its a very good product

paul t on Aug 25, 2019
BEST ANSWER: Unsure. I have a DeWalt 611 and even though it is said to fit I had to become very inventive. In my case it fit so. A sideways position making it difficult to use.
Does it work with the Black and Decker RP250 model?
EdenI on May 29, 2018

i have circle jig which best router bit to cut birch wood ? thank
redbo on Aug 22, 2016
BEST ANSWER: 1/4 Up spiral bit if you want the front surface to have minimal tear out. Straight bits work fine as well.
Could I manage to cut a 5-5/8” circle if I use a 1/4” bit? Just wondering if 6” is the absolute minimum
Mike H on Aug 21, 2019
BEST ANSWER: I measured the minimum distance between the locating pin (center of your circle) and the center of the router to be 2 3/4 inches. So, it would appear that the minimum radius would be 2.75+ your bit diameter divided by two. At least, that's my understanding. Good luck.
MICHAEL B on Oct 14, 2016
BEST ANSWER: sorry never tried so don't know
Will this jig work with the Ridgid Trim Router? Model # R2401. Thanks!
