Jasper Circle Jig Model 240

Jasper Audio Circle Jig precision router attachments convert your plunge router into a precision circle cutting device.

It makes round circles at any depth you choose, from countersunk to cut-through, and is perfect for tweeters, midranges, woofers, and even ports and input terminals.

The Jasper Model 240 cuts holes from 1" to 18-3/16" in diameter. This makes it the ideal tool for creating highly accurate cutouts in custom built speaker cabinet baffles.

Jasper Circle Jig Model 240 is rated 4.75 out of 5 by 12.
Rated 5 out of 5 by from Jasper Circle Jig system works Great!I have a Freud 2000E and it bolted right to the jig. I had to cut a 3-3/4" hole in plexiglass and was worried it might be too small for the jig to work well. It was nice to use such a well crafted tool. Thank you.

Rated 5 out of 5 by from Love this Jig!!I bought this jig for my router to cut speaker baffle circles and it works wonderfully. Circles come out perfect and at the exact measurement I wanted.

Rated 5 out of 5 by from Awesome productThis tool makes life so much easier. Set up is easy and works like a charm. Love that it goes all the way down to one inch. I am a 12 volt installer and build boxes and other custom pieces on a regular basis. I decided to purchase this piece after using a co-workers but the smallest size hole his would cut was 7in. I use every chance I get.

Rated 5 out of 5 by from Excellent productPurchased this after years of using home made jigs. This product is excellent and very precise hole to hole. Even though there are holes at 1/16" increments, there are some speakers that don't quite fit due to metric sizing.

Rated 5 out of 5 by from Great tool for speaker builders!Speaker cutouts up to 18" diameter. Internal bracing "ventilation" holes of any size. Nicely covers the same range of useful diameters as the #400 and #300 without the need to swap jigs. (Been there ...)

Rated 5 out of 5 by from Works as advertised!Bought this circle-cutting jig after recommendations from a wood-working friend. He has a similar jig from Jasper but his doesn't do smaller holes.The hardest part of using this thing was finding the holes that fit the plunge router we were using. After that, usage was very straightforward. Occasionally it's difficult to get the jig/router/pin assembly to line up correctly with the 1/8" hole for the pin, but once you do, you get perfect holes.One thing we noticed is the hole is slightly smaller in diameter, maybe 1/16", from what's described...Not a huge issue in most cases, but something to be aware of. Maybe our 1/4" router bit wasn't perfect.
